Bitcoin Forum

I've been thinking about it since last night and I couldn't find an answer to myself.
I know that there's a 21 million block cap and we wouldn't actually be here to see that time it comes to that point.
But assuming that we have reached reward era 34, what happens then? Miners wouldn't have any rewards from mining then.

Anyone care to help explain a few things for me?

I am not sure if it is designed to last forever but the real question is if it is also going to last forever because I am sure that if most people quit that it would not last forever.
It is all going to depend in what the users are going to do and how they react to Bitcoin.

Bitcoin is such an oldtimer. I don't think it will last forever (even the planet isn't).  :D

The blocktimes are too long, the client is too old. I don't see much development. People use it because it's well known.

You are forgetting that Bitcoin has transaction fees. The total sum of transaction fees paid for transactions in a certain block goes to the miners solving that block (in addition to the block reward). While total transaction fees today are typically significantly less than 1 BTC per block, this total sum is already significantly higher than a few years ago.

In future, transaction fees will progressively increase in relevance compared to block rewards and ultimately entirely replace them as an incentive to solve more blocks.

You also have to consider that with decreasing block rewards, Bitcoin's valuation will very likely increase significantly. So mining might still be profitable, even if the amount of Bitcoin obtained in the process is only a fraction of what it is today.

ya.ya.yo!

me too i am not sure if bitcoin will last forever but i think it would go longer than we expected . lmao if bitcoin would never go last i am sure that there is some new coin that will be alternate of bitcoin . if we imagine bitcoin is still famous until now so maybe this will last forever .

Another thing, I heard the mining power consumption of Bitcoin will be the same as the country Denmark in a few years. That is not sustainable. People don't want that. In other crypto's you can secure the network with staking. Easy as that.

No in my opinion. There are simply too much issues with it at the moment.

For instance, block times are way too long for instant transactions. The blockchain is getting too bloated. It's using up energy inefficiently.
One day, bitcoin will fall.

i think yes you can say. the reason is that it has so any plus point which make it possible that bitcoin will stay forever. for example the interest of the people. the stability of the rate specially in present time. the steps taken by by the government of China and Japan.

I just hope that day will not come any time soon.
I mean, it's probably okay if there's something that can be a replacement for bitcoin but while there isn't, I really do hope it doesn't happen yet.

Eventually after all coins have been mined there will be no block reward for the miners. Fees may be higher then though so there will always be an incentive I guess.

I don't think anybody truly knows what lies in the future though.

why should anything last forever? if old stuffs refuse to leave, how new (and greater) stuffs come? for the sake of development, don't expect anything last forever.

Maybe it's ment to last forever but can it really last that long..Since is lmited in amount maybe that couldn't be possible. But who knows what future brings.

Block times issues - Being addressed by SegWit / Lighning network / side chains / Off-chain solutions ....etc.

Energy inefficiency - It is not using any more energy than banks and other financial institutions use on a daily basis.. they too have computers / servers / aircon / lights / CCTV etc...

Bitcoin being bloated - The scaling of hard drive technology, will in future make this a non-issue and you could always run a thinner client/node.

Want to take another crack at it?

If mining reward is zero when all 21 million bitcoin will be in circulation than miners will get total transaction fee as mining reward. And i am sure at that time different miners will set different transaction fee per KB of transaction considering their cost and bitcoin price at that time. If price go higher fee will be lower in terms of bitcoin and vice versa. I think bitcoin can survive even without any block reward for miners.

i think it is meant to last for the whole time of people because this is the best currency we have ever had and i think it will remain like that

yes, they will have transaction fees.
and if think that's not enough, just remember about supply x demand. with less/zero bitcoins been generated every day just a few satoshis will worth much.

1. Double spending.
2. Speculation. There's no guarantee that technological advances will outpace blockchain bloat growth.

i remember there was a thread like this before. if all coins were mined like 21M of them in the far future which i think we'd all be dead.
Miners will still receive transaction fees and so theres no stopping unless people stop using bitcoin.

I hope that bitcoin can have longer life than $ and if bitcoin gone other crytocurrency will change him like example bitcoin gone now and litecoin prize per coin go to 500$ minimum per peace so all situations are good because there are hunderts cryptocurrencies.

i think yes the interest of the people and the price increase shows that bitcoin is design to last for ever. i think if w compare bitcion to other crypto currencies we can understand that bitcoin is developing and maturing with a high speed.

i do not think that bitcoin was designed to last forever. it is just an invention which will disappear once something more developed is invented. nothing in this planet can last forever AFAIK

well it is impossible to avoid any better technologies in my opinion because there will always be new inventions that will be better than the previous ones so bitcoin wasnt created to last forever

Bitcoin has really been convinient for me ever since i discovered it, so i use it while it's still around. It's not as old as people are saying it is but one day indeed the mining cap would be reached and the remaining bitcoins would be circulated around; where would it end up? When someone converts their Bitcoins to Fiat, its not like they transformed them; its actually a trade of buying and selling so therefore it would keep being circulated around for generations until slowly and gradually people stop using it.

I assume, during the reward era 34, the block reward would be around ~500 bitcoins. Yes, newly generated ~1 satoshi + 500 BTC from transactions fees.
As of now miners are gaining ~0.7 to 0.8 BTC tx fees with each block rewards. 2 years back it was around 0.15 BTC. Miners will have a definite reward for their efforts always, bitcoin price is the another factor will ensure that always.

No bitcoin cannot last forever. In fact nothing can last forever but it doesn't matter to me because until i am alive bitcoin will be alive and will grow year by year so i don't think we need to care about that

Off Course Bitcoin is designed to last forever.


Here are few reasons :

Bitcoin is nothing without blockchain. Blockchain actually powered it and enhanced it become a digital currency.

Bitcoin is peer to peer network.

As already people from allover world have accepted it trusted it and implemented it. And till last man on land bitcoin will be at that point.
If we consider no mans land then nothing will be here.

Bitcoin is a real invention as like a dream comes true.

I think that it is not a good way to think,because in my opinion nothing is designed to last forever,at least it is not ready or possible.
Especially will bitcoin,it is of course the first real cryptocurrency,and the most popular one,but if we will see the same growth
of cryptocurrencies and growth of their popularity,we may see another crypto (or maybe some altcoin) getting bigger and bigger,even
to the bigger size of these days bitcoin.
Many things may happen,but i hope that bitcoin will last forever,and rise

I don't see bitcoin survive 50 years of innovation and technology. Innovation is just growing to rapidly which makes it hard to compete for bitcoin.
In short, we can enjoy bitcoin for some decades, before something new will take over

I agree. Because some of have already predicted that there will be any other currency in future having more value than bitcoin.

Bitcoin is nothing but just an altcoin as many are there.
But Bitcoin is special bcz of its value. Bitcoin is only altcoin have highest market exchange value. No other cryptocoin have reached to near yet.

But in future there may be possibilities of any new altcoin having value more than current bitcoin price in market.

of course bitcoin is not designed to last forever, in my opinion bitcoin will go on for about 500 years until it will be replaced by some kind of a better currency, thats my guess for it

The OP is talking about our lifetime and what happens when the block reward becomes low.
Of course, nobody knows what will happen in 500 years time.

Bitcoin doesn't have enough coins to supply everyone around the world and its also unpredictable when your payment finally reaches its destination. There are a lot of altcoins out there trying to dethrone BTC and one day something will or is in the process of doing so.

Long before this reward era 34 even start, fees beome much more important than base block rewards. Now the situation is quite different, base block 12.5 Bitcoin reward is much more important than any fees you can reasonably collect (up to 1 BTC?).

At the moment the core isnt giving too many importance about how will be the future about bitcoin, but we believe on that moment the fees that we nowadays support the network would be the fee that will keep the miners active. But sure that would be insane till some moment as the coins will be less and less all years,soo this system still with some problems.

I think all bitcoin users wishing that it will be last forever because bitcoin is great other source of income it can also help us to increase our monthly revenue. That's is why the miner should have a bonus always to motivate them to expand their farm and to have more supply of bitcoin even the new users has a huge demand of bitcoin they can support how many bitcoin they want.

There are 64 more halvings left to bitcoins. If we compute 64 x 4 years equals 256 + 4 = 260 years. So bitcoin is not designed to last forever there will be a time when bitcoin will stop. But it is a long way to go we are all dead before that will happen. But if the quantum computers invented by NSA will have a negative effect on bitcoin then bitcoins will no longer reach 50 years.

Nothing is for sure but there is a chance that sooner or later another cryptocurrency will make its appearance and it will be an improvement version of bitcoin which means anonymous,safe to use and much faster.These features will make it ideal for instant payments and it will become the most used digital currency.Of course bitcoin is not going to lose its value but it will be only used as an asset,the same has happened with gold and dollar for example.

I dont think it was designed to last forever, there is a time limit but if bitcoin keep being develop and use, some of the researcher will find way to make it last longer,  if there are no researchers able to do it then we will have to find new coin

Nothing lasts forever. There will come a time that a whole new technology replaces what we have right now and everything will follow from there. Change is inevitable and bitcoin is a part of it all. Bitcoin might get to survive a long time, and I hope it lasts longer and more stable than I do, so I could make the most out of the benefits it has to offer.

I concur, nothing lasts forever.

As long as bitcoin has it demand and price then it will last forever :)
Bitcoin is a digital currency, unlike real money that can be destroyed and that mean no lasting forever :P

Unless, there's a bigger bitcoin competitor in the future I am positive that bitcoin will last for a long time :)

What do you mean by time limit ?
Bitcoin has limited supply, not a limited time ;)
If people keep using bitcoin then it will has it demand too :)

i have heard from my friends that bitcoin will have more demand in the future. because people are investing in bitcoin. but on other side as miming remain no profitable any more therefore most of the miners will stop mining which will increase the demand of bitcoin. so we can say that the demand increasing mean the increase in value. therefore i think that bitcoin is design for ever.

Nobody knows what is on the future and we cant say if bitcoin will going to last forever, but i think as long as many are still using and supporting bitcoin then it wont be gone. unless new cryptocurrency appears and dominate bitcoin.

For my lifetime? Yes!
But really forever? The day money becomes unnecessary, bitcoin will too.

Yeah they say that it is designed to last forever but is it really going to last forever because it also can go the other way where it can disappear.
The only thing that we can do is wait and see if really will last forever.

In my opinion I think it depends on various factors such as ‘how bitcoin is going to adopt market conditions and vice versa’, how we are going to deal with it and how the future users will deal with it. Honestly speaking bitcoin won’t last forever but it will last for a long time (which might be anything in between 100 years to 1000+ years).

In my opinion i don't think it will not last forever, bitcoin is good for now and the value of it is high, but no one knows what will happen in the future we all know that there is no forever in real life. Do not expect too much or you would get hurt.

I think BTC depends a lot on those who use it. If BTC overcomes all the halvings and people still use it, then it continues to live. If mining isn't  profitable at all and people  stop using btc much, it dies

I think if the block halving continues the way it is, eventually after so many years the value of a block would be quite insignificant that most of the mining sector would quit and go back to earning the regular money. Bitcoin would still be distributed throughout its users though, and i think that if the demand should continue as it is, the it would never die.

Here we can understand that bitcoin is beginning to develop. I think the interests of the people and the rise in price of bitcoin
shows that bitcoin is designed to thrive and survive.

I hope that bitcoin remain among us till the end as it is more beneficial currency for jobless people they are now earning a better profit from that currency and now they do not need to beg for job to the officers, but they are their own boss.

Well, BTC will be with us at least for 5 years.I assume there will be a form change by 2020.

Bitcoin is designed well, however at some point in time I think it will need to be rebooted or something, for wouldn't it get harder and harder to get confirmations and such.  I understand that fees will be applied to all transactions once the block have all been found, but I would think that as long as users use it all th tie, it will be there to be used.

Our bitcoin machines, so called miners, will not be miners in a near future but approval machines like notaries.What changes?A lot....A hint, scale economics.

I dont think it was designed to last forever, that is why we need to support bitcoin to keep being developed, so it can last longer,maybe with the update and development bitcoin can become last forever

If there will be a fork who is going to decide the timing?

BTCX new BTC with 1.000.000 coins.All premined :)

Agree as long as there are lot of users! And we could conclude now that the demand of it is getting higher and higher every year so meaning there are lot of peoples using it because of its popularity in the world :D And lets hope that it will not really die :D and we can say that there is a Forever! :D

that's right, in my mind bitcoin is more flexible, but their just mingle into the digital environment for naturally. and basically bitcoin is made for easily be mingle with our digital community.

One day all bitcoins will be mined.
That means no transactions will be confirmed anymore.
I think that coins can still be sent, but without the confirmation, I don't think that people will still use it.
So no, I don't think bitcoin will last forever.
Besides, I think that the confirmation times will become so slow that long before the last coin will be mined nobody will use bitcoin anymore.

I dont think bitcoin is really desinged to last forever because i know for sure that allot of people are making money with it but not for the rest of their lifes you know allot of peopel are doing well with bitcoins but will that stay?

I dont think allot of people will stay for the rest of their lifes into the bitcoin because one day he will drop down that much and rebuild all of it again so that makes very many people sad.

the possibility there are because not all bitcoin successfully mined and adventure is still far just enjoy what we could get from  bitcoin.

I dont think bitcoin is desinged to last forever because i know what the price of the bitcoin will be in the future and if we are all holding like most of the people are doing right now it wont last long.

Do you really think that the bitcoin is not designed to last forever i think that the bitcoin will stay always the same maybe a higher price but there are only more and more people using it.

Up to date bitcoin network is still safe for be used and there are not found weakness of it, but if we talking about bitcoin is desained to last forever, i think there are not people who know it, because the technology always growing up.

I think so. Bitcoin has no weak spot that people are capable of abusing. People can only misuse Bitcoin but people can't spam Bitcoin to the point that it will go down. Bitcoin is a currency but it exists on the internet. Ask yourself, do you think fiat money would last forever? If your answer is yes, then Bitcoin will last forever, as well. If your answer is no, then maybe it's because you have doubts on Bitcoin.

No one really knows  when bitcoin would  last since anything in this world doesnt last forever but  i could somehow assured that bitcoin would last a little  longer since its already been used  by people  and the adoption of bitcoin is  growing day  by day which causes for  the price to rise up, as long their are people  who use bitcoin it wouldnt  easily die.

bitcoin will be designed to last until internet gone and being replaced by another far superior technologies that maybe will be happen in the next age

there is so much nonsense in this thread... it's actually very simple, as long as there are a few miners and people hosting nodes, then it will continue to exist.

That is way too far but if ever it is all mined you are right. It will just be rotating and be used for big koney transaction. If you try to calculate it even just for the price now a million bitcoin is 600m+ dollars. That is way too huge.

yes i am hopeful that bitcoin will stay for ever because it is now becoming the world number one crypto currency and all the people of the world will be using bitcoin in all over the world.

Bitcoin is already known as world number one crypto currency and in the way to become the mostly used digital payment processor. Bitcoin will survive till there will be internet as well as few peoples hosting nodes and few miners keep mining, and as of now bitcoin community is huge so i don't think there will be a situation where there will be no one supporting bitcoin in future.

No one can really design something to last forever because nothing in the human world is ever perfect. That said, Bitcoin doesn't need to be perfect. Nobody knows for sure how the network will hold up after mining ends but that's okay because the code can simply be modified/enhanced/updated along the way. So in that sense, it certainly could go on forever. The Bitcoin of the future is likely going to be very different from the one we know today, the same way descendants are different from their ancestors.

I guess its a yes because bitcoin is like a gold. Bitcoin is all over from the cyberworld so it cannot disappear no matter what. Just like gold it is all over from the land just mine it or search it then you will the gold or the bitcoin. Another similaralities is the value of the is continuing to up.

May not last because it will last as long as human beings want to trade and use bitcoin and as long as bitcoin network last. There is still no hope that bitcoin will last forever because there will be only 21 million bitcoin and if all people start using bitcoin then there will be shortage of bitcoin and price will be sky rocketing and with such high rate people will refuse to use bitcoin rather they would choose other coins.

It sounds pretty poetic but "nothing last forever" so Bitcoin won't last. There's a paper where it's said how much coins and how much time it will take to mine the laaaast coin. This thing will erupt a situation that I really don't f****** know because it will happen in a very distant future --more distant than the paper said of course, because it's not a end prediction. When this day come we will be using hover cars like dr. Brown. It will be great.

Yup it is better than gold according to me. I believe Bitcoin has the potential to buy anything in the world and price will best part of the Bitcoin because as I know this is the only stock in the world which is costlier than anything.

Yes nothing lasts for ever but bitcoin will stay as long as human will stay in this world or at least till internet survives in this world. There is no meaning of expecting bitcoin system to survive even after human race fails to do so. So, I just want to argue that bitcoin will stay with us as long as we need it.

There is no point of expecting bitcoin and the internet to survive for ever in this earth whereas there is no guarantee that human will survive for ever in this earth.

The bitcoin price is volatile. But as long as it is under good development, the price will rise in the long term.

I didn't design it so I don't know whether the original designer(s) wanted it to last forever or not, but I don't think that bitcoin will last forever. It will last much longer because it's been with us for the longest, but by time other crypto currency will grow up next to up in technology and slowly take the place.

Bitcoin is going to facilitate us all for decades from now on wards. It is very difficult to say anything whether it will last forever or there will be some other thing more advanced and usable than blockchain in far future. We can not even imagine how the world will look like after 100 years as science and technology is at full speed even now.

Not sure if Bitcoin will last forever, in fact we can't make sure about anything to last forever in this world. But i believe Bitcoin is designed already to last for very long time .

yeah, the price is really volatile, but it is the main reason what makes bitcoin so interesting for me

Nothing last forever and bitcoin will also die after few years and something better will replace it

Bitcoin is definitely designed to last, and the best part is that there doesn't have to be a massive infrastructure to maintain it. There can just be a few people who show up and get the data and nodes up and running, and boom, you have a running blockchain that can be used by anyone able to connect to it.

Nothing to be too special, but extremely effective.

I don't think that bitcoin will last forever but im pretty sure that it will last longer .no things last forever all that are mined ,bought etc .time will come it will disappear even our earth don't last forever so no thing on this earth will last forever .bitcoin technology is good now it has a good future in terms of it use .its only the start for the popularity of bitcoin so it will take more years and better to take advantage that we already known bitcoins first.

thats true, the price is really volatile right now but it is because of the fact that it is controlled only by people so it can last for a really long time

The main thing here is that bitcoin wont die if there still someone who uses it and someone  who buys it and for sure it wont easily die on the long run, Bitcoin could die if the adoption would  lessen and theres  no activity on the bitcoins ecosystem and  user would dump all of their coins then it would surely die.

so long as bitcoin is being used, sent and people make transactions bitcoin will last forever and so are the rest of the coins. so long as there are miners and people using the coins they are all designed to work and last forever. most importantly, as long as the value stays good it will work.

In my opinions, bitcoin is should designed by the logarithm and i don't think will be designed for last forever maybe will there a some development of the logarithm of bitcoin are used in this time and it's not designed for last forever.

I hope that bitcoin will last forever,but unfortunately nothing lasts forever.

I don`t care about the mining block cap.Bitcoin can survive without mining.

Bitcoin will last forever only if there are people who support it and use it everyday.

What is the designing in logarithm, really I could not understand how logarithm implemented in bitcoin development also I just checked in Google is their any other meaning for logarithm other than mathematical usage.

I have read many times that the growth of bitcoin might follow exponential as it will grow rapidly in future than past always. Other than this, I could not understand any relationship with logarithm with bitcoin ecosystem and more particularly for the core concepts designing for long lasting.

Whatever was the intention of Satoshi, Bitcoin is going to last forever. The reason for this is the fact that people would always want something in return when they're going to give another person a material thing. In an instance, would you just give you cellphone into another person? No, unless you're going to trade it for another phone or sell it for money.

Money would always be involved in this world because of the very nature of humans.

it is just spam, don't think too much about it. he may have had something like algorithm in his mind but wrote logarithm!!! and in reality he meant to say by design :D

anyways, bitcoin was meant to be used as a peer to peer money and way to transfer money this way without a need of a third party like banks so it can last as long as at least 2 peers are transferring bitcoin and there is someone who is mining the blocks.

This made me smile.  I will give my phone for free if I will give it to my family or love ones.  But of course would sell it to someone for possible upgrade of my current cellphone.  Anyways, yes, bitcoin I think is designed to last forever.  And the fact that many people right now uses bitcoin and already invest some of good amount of money, then there is no way that bitcoin will be stopped.   

I've read through all the comments and I think this is the best explanation. It is simple yet very informative.

To sum up all the comments which make sense to me: Yes, Bitcoin is designed to last forever.

There is no project that created by man that last forever even if it is well established as of now. At some point, Time will come that bitcoin will be abolished because of new coins that is more advanced to it and have better feature, mark my word.

The amount of Bitcoins is limited, that is the fact that we l know. Whether it could last forever, it's hard to say. This is completely new concept of virtual digital currencies with no prior experience so any prediction is possible. It's possible that some new and more advanced technology (currency) in the futrure replaces Bitcoin.

of course it is volatile because it depends only on people and nothing else and i think it is a really good thing

I don't think that Bitcoin designed to last forever. There are several scenarios in the future, which can spell doom to Bitcoin. For example, if a supercomputer which can crack Bitcoin private keys are invented, then it will become impossible to safely store Bitcoin. Another scenario is the 51% attack. What will happen if someone invents a mining rig, which is 1 million times more efficient than the others?

Bitcoin is getting developed more and more , It takes time but we are getting there so I personally wouldn't be worried about transaction speed etc... we will get to Lightning network , eventually.
the only issue I can think of is the ability to crack the private keys easily If computers keep getting more powerful with time but If the algorithms could be changed , I don't think It's going be a big issue.
I personally like to think that It could survive forever If the development stays active, because with more  altcoins with new features keep popping up , Bitcoin has no chance unless they continue to develop it.

Its volatile because there are lots of  people who uses it thats why  its  keeps moving its price and thats a normal thing for bitcoin. In fact bitcoin was created  for many reasons it may not last forever but we could somehow assure that it would last for a long time as long there are people who still uses and  buy it.

I don't think this is accurate when you consider the halving time, it would happen eventually but it would take a very very long time with the halving occurring gradually, also BTC is not set in stone, at that time I am sure there would be a solution.

A new technology will change the old one, thats a common thing in this world. Well I think we dont need to worry for now since there is still no other cryptocurrency who really can beat bitcoin.

What is designed to last forever?
Technology we have around us now, our buildings and houses, countries, banks, our current money or even this planet earth?
Nothing will last forever.
Realistically, in 100 000 or 1 000 000 years we can't be sure that even Internet will exist.
So, enjoy current ride with Bitcoin and don't think so much about the future.
We can't even predict what will happen tomorrow, in one month or year.
I will be personally very happy if value of Bitcoin increase 10-20 times in  next 5-10 years.
It will be enough for me to get rid of my current job and start enjoying life.
For rest I don't care really (since I can't influence it).

Bitcoin will be around for years but it wont last forever as there is no permanent in this world. the important thing is now, many are using it and what matters is the present.

any kind of technology will die some day in the future but that future is not near at all. and also you should know that technologies like bitcoin are always evolving and matching the new world as we move forward so this future is pushed a bit more forward again.

Maybe but bitcoin is an open source and it can/will be improved in time greatly. But you can never know, bitcoin will probably (surely) outlive you, so for you it will last for ever but I see the bitcoin as a side option in the future, probably will never get into the mainstream or will take pretty long time.

The halving speed is estimated to be 3 years now, maybe more in the moment when I'm writing this post. You don't need 100 years to see the whole computing technology at an unimagineably different level. But bitcoin is a virtual technology that USES computing technology and as a virtual technology, it can adapt to the development of the computing. However, as hard it's to predict the future of computing, it's hard to predict the future of bitcoin, but I think it'll change and - I hope - survive in the end.

I guess its designed to stay alive forever because the miner fee is adjustable and that will jsut take over when the block reward becomes too low for the miners. Atleast i hope it stays alive forever.

in my opinion it actually is designed to last forever and it will because bitcoin is a perfect currency

Bitcoin was designed to last forever, however it is far from being a perfect currency. While there are a ton of great things about the Bitcoin protocol that can be applied to other currencies (or just overall for that matter), the confirmation times take too long and there is always the risk of someone controlling the blockchain.

Solve the confirmation length, get faster wallet syncing and get rid of the potential for someone to control the network with 50%+1 of the network, and you will have basically the perfect currency.

I guess so too, because as long as there are users all over the world it is going to remain alive. And the designed of having 21,000,000 in the circulation once was this already reached. For sure the cycle is just going to keep on working and moving because that is going to make the price of bitcoin unstable and fluctuating.

I want to clear some misconception here - please don't use term 'forever' most people by forever means a lifetime of a man - which is totally inappropriate use for this word.

And now stop and ponder for moment about human inventions and development of our tech. Have you seen atomic shelters from cold war era? With big computers with processing power lesser that current watches?

Do you see how Moore's law is affecting our progress? And now apply all this to bitcoin - it might last for 10, 20, 100 years - who knows. But I am sure that in the future something else will take its place.

It might be over a hundred years from now, but I assume it will die and something else will take its place. I don't think Satoshi anticipated Alt coins when he created Bitcoin, or even volatility. He was probably thinking of an alternative currency that everyone can use and be happy with, and when the time came people would just continue mining because it's a good currency.

Even if something replaced bitcoin in the future, bitcoin's advantage would be that you could easily exchange it to that new currency. Bitcoin was and is a milestone. The new milestone should keep the advantages of bitcoin so exchanging from bitcoin to the new milestone should be easy, quick and cheap like exchanging between cryptocurrencies.

The fee is ment to be the reward by then.  think about it if it lasts that long and everyone is usuing it the fees will be massive.

The creator of Bitcoin has to be very smart. He had to calculate everything with care, predicting the hash speed and the user number and all the others.. It's been 7 years since Bitcoin has been published and we've still got a lot of Bitcoin left to be mined. But the big question is.. When will the mining reach its end and what will happen? What happens when we will reach 21 million Bitcoin mined, will the price go up to millions or even billions?! In four years, the halving will take place again. That means 6.25BTC per block, and by 2024 we will have 2.1275BTC per block. The price HAS to go very fast up until then, because people will have to continue to invest in mining rigs to make profit. And to make profit, you need to earn more than you paid for your mining hardware. It's a very interesting question. It's not going to really last forever, but it will last long for sure.

yeah bitcoin is one of the most volatile cryptocurrencies but it isnt a bad thing because it can make us money

it's designed to last forever for the current system, just hundreds of years or so with the halving taking place every while then it's eventually going to be few satoshi's per block and these satoshi's would have a significant total all value at that time.

The block reward will be 0 in a hundred years. Then the transaction fees will support the network in the future.

It should last for long time, beyond my life time but not for ever. My challenge is if the world power wont go against it later. Like every other currency if it get enough power as a currency and any power covet its ability to work without them, they might come after it. And if the power is from well to do one, I cant say what can happen then.

Definitely bitcoin will survive centuries because it is not dependent on single central authority who might close and go away from the business. Bitcoin depends on people and run by people. So, there are no possibility for bitcoin to get shut down.

Reading through all those posts made by the users here many peoples are saying that bitcoin is not going to last forever due to different issues. :(Actually i dont have much technical knowledge about bitcoin but i love using and earning bitcoins and i hope and wish that it last until i am alive.

I think bitcoin is here to stay, as long there are people using it, it will lasts. Maybe in the futre, we will see a better cryptocurrency with better features of course there are innovations on going and whoever or what coins the people will support, it will lasts.

Actually I don't know if bitcoin designed to last forever. Just all I know everything has an end., therefore I think bitcoin will not last forever because if the users gone, so how will it last forever it will disappear.

Yeah I have the same question too, although I do know that it's gonna take almost forever until it reach its point, there must be a time when miners don't have anything to mine then what would happen ? will the answer be forever or will it come to an end someday ?

Yeah you have your point, many things could happen like bitcoin coming to its last destination, people giving up on it, etc. but one thing for sure, if these scenarios are ever gonna happen, it will be long after we'll have been out of this world.

Same here  :) i dont think if bitcoin designed would last forever. Nothing would last forever! But one thing im sure, it would a long term survivor. But  if users always used bitcoin then theres a possibility that it will long last until the end  :)

It aint. But it is designed to last longer than our lifespan now so it could be passed to another generarion which will be the one who really make use of it a little better. Remember geniuses are born and someone with the right method could make it more usable.

You have a point in this matter, we shouldn't expect too much in it. For me there no is last forever, Besides bitcoin is not designed to last forever but design to give  hope to the people who are financial broke, to the people who are totally hopeless in life and for the jobless. That's just in my opinion and thought.

yes, bitcoin is designed to last forever if bitcoin can be accepted legally by government at around the world.
if that's not happened, bitcoin only can be long last but too fast to say that bitcoin can be last forever.

Bitcoin won't last forever because everything in this world must come to an end. It's like us, even we take care of ourselves everyday, eating healthy foods, going to the gym, living in a healthy lifestyle, still in the end we are gonna die. We just don't know when will it come and it goes the same to bitcoin. Many people are using bitcoins and doing bitcoin to earn bitcoins but who knows that one day when you woke up, bitcoin is gone, you don't know how, why, what, when and so many questions you wanna ask but no one can answer you because they don't even know too. Let's just enjoy using bitcoin right now because we all know that someday it will come to it's end.

I don`t think that amount of bitcoins have some connection with bitcoins life. Simply cause many times explained question is what will happen when all coins are distributed. Bitcoin have many decimals, with limited amount of coins and rising demand price can just go up, that`s why there is a chance 1 satoshi to worth a lot more then now.
All that are speculations, if people continue to use bitcoin, and in case that bitcoin become mainstream one day, I think bitcoin can last forever. Bitcoin is still rising, and I think we need to see bitcoin much stronger every next year if we wish to last forever.

In my opinion it was designed to be used in the virtual world and can be also used in the real world if we are going to convert it in cash but it was never designed to last forever, because forever is just a word. Everything in this world will vanish in time. We don't know when is that time but for sure it will come. Only God knows about it. He said that it will come like a robber that we won't notice. This world is so cruel that's why God's already put an end to it including bitcoin will fade away.

For me, it depends if bitcoin is going to keep on rising then I guess many people are going to get interested with it and they are the ones that are going to say that bitcoin is going to be used until fiat money is going to gone because of it. As long as we are here, the users of bitcoins then it is going to keep on alive.

well maybe not forever but for a really long time bitcoins are going to be impossible to actually hack

Well, to be fair, if you had a quantum computer that actually worked then you'd be able to "hack" the network, however that so far isn't a possibility and there is no reason to worry about it. The first trials with quantum computing haven't been particularly effective so far, so I have no idea what to assume is going to happen in the future.

Quantum computer is likely to break the ECDSA that is used in Bitcoin addresses. Private keys can potentially be derived from a public key and that means the earlier address with only 50BTC block reward in it can be compromised since they used P2PK instead of P2PKH. Newer addresses can be hacked if the private key is revealed after a transaction. I don't see it as a threat since we can easily change the protocol, making it resistant to ECDSA cracking.

That being said, Quantum computing is quite expensive to use and Bitcoin would not be the first target of them.

If there is a possibility of quantum computing attack, can we change the protocols early to avoid the attack?

I don't have a clue if it is forever or not, nothing lasts forever. Lol. On a serious note, I hope that it will stay long because it can be very useful in the next generations.

bitcoin network will last as long as user use it and till the day of finding its security loop hole. once hacker find its weakness then they will destroy it. but if this doesn't happen then buy-in will lay as long as we want even there is 21 million limit but that would be enough because 1 Satoshi rate would be around $10  to $1000 at a time

Yes bitcoin would last as long as we want and it's secure from hacker. Once hacker find its vulnerability then they would destroy it. Also 21 million limit would have no effect because by timed we will start using bitcoin Satoshi unit and at that time 1Satoshi would worth $100 at a time

bitcoin currently has limited production system. mining system that can be discharged at a certain rate.
I think bitcoin will continue to survive and someday bitcoin will continue to increase prices were high.

When 21 Million bitcoins are mined we will not be here probably but the profit of miners will be also from another source.

Since the block reward will be decreased through the time the transaction fees will be increased(if the value of bitcoin will not change).

Nothings lasts forever but the core dev will continue to support the bitcoin and make it better and better.

You know what dude, I don't think there is last forever in bitcoin. Though I'm a bitcoin enthusiast, Only I know in bitcoin it will become a big help to anyone if they adopt the system of bitcoin. and lastly, miners always be in the stage of risk every time they invest in mining then in the last they wouldn't have any rewards from the mining sites they invested.

I do believe that is going to happen because the supply of bitcoin is limited and that is really destined for bitcoin to last forever because of its limited supply.

As long as there are transactions, trades and people who buys and sells bitcoin then it is going to keep on remaining and being used.

That's why I believe that it is going to remain forever.

yeah I have the same thought, nothing will last forever even this planet has a time when it comes to an end so I can't assure that bitcoin is designed to last forever. But one thing I can say that it will last a long time before it reaches it destiny.

The bitcoin will not stand still. It is in active development phase since the inception. I think its momentum will be maintained.

Actually i think bitcoin is secure from hackers and bitcoin have successfully came over several hack attempts on its network in past. By now network is strong enough to remain functioning in any types of known attack methods and bitcoin codebase is tested over several years and also being tested right now to make it secure and to withstand old/new types of attacks.

I do think that Bitcoin is designed to last for ever that is why they made use of the fact that it is a online currency and in the future most things will become digital and online.
It is not sure if it is going to last forever but I am sure that that is there plan.

Bitcoin is being  created  with purpose thats why its developer and the founder itself have  launch this  project and  we already  exprience and  witness the  uses and  opportunities on using it. It may not last forever  but  i could somehow  assume that it would  last long even more.

Technology will increase on both sides, it's like a chess game, one play after the other but I think bitcoin don't will be the primary crypto currency in the future, there's a lot of things to happen...

It might have been, but we will never know if it will really last forever or not. Anything can happen sooner or later which could bring it down to 0, so we have to be wise.

At first the bitcoin is an algorithm and I think the characteristic are the open source and is not the last forever because a various developer is can for developing the bitcoin into a new technology and I think bitcoin are not last forever basically the algorithm are open source.

We don't know yet.
I am not really sure if it is designed to last forever.
It is all depends in the users performances and how they will react in Bitcoin and how long they will support it.

as we cannot think about the world without fiat currency, so a time will come when we will totally depend on crypto currency and hope that bitcoin will on top and ever one will be using bitcoin as their first priority.

Hopefully there might come a time like that, however I personally think that's a long time away and I would personally prefer to always have some cash available instead of completely relying on a digital system that could have things go wrong with it. How that would work, I have no idea.

Yes, fiat currencies will find survival ways to compete with bitcoin always. But, bitcoin has all the possibilities to dominate in worldwide financial systems. In future everyone will be needing of an electronic format of currency, cryptocurrencies would be the appropriate solution for them at the time.

Yes, bitcoin would be the first priority for future generations to use instead of fiats, surely bitcoin will last for ever as long as there would be some demand.

for me bitcoin is something that has a great future. I imagine someday will last until bitcoin bitcoin recognized internationally.

1 satoshi = $100 is really unbelievable and  every bitcoin holder would want that to happen. And anything is possible, one day if it happens, it could be the best thing that can happen in a bitcoin enthusiast's life!
Bitcoin is a big successful experiment and as long has it is maintained and updated, it should run well without any problems. The Devs should keep the code updated, the bugs fixed and be on high alert as bitcoin could be under heavy attack at any moment from anyone...

No, in my opinion it is designed to last until no one use it anymore. Because that is the only reason why do bitcoin exist, because many people are using it and getting benefited with it by earning bitcoin in an easy way. Do you think that a car will last forever if no one use it, just left there in the garage and got stocked for a long time ago? It's machine will not work anymore because it didn't have any maintenance because it is abandoned by someone. It goes the same on bitcoin it will get disappear in time when no one use it anymore and it will not last forever.

You can't compare bitcoin to a car, it;s not the same. Bitcoin is designed to last and has open source code to be improved day by day.

The survival of bitcoin can never be predicted though it is created with certain limitations of coin generation. When popularity and acceptance gets increased gradually the long lasting of bitcoin as well other digital currencies will increase as our technology is completely open, which can be programmed accordingly. If it doesn't happen the same technology emerge with some other name and reach the people.

How dumb  to compare a car and a digital currency? lol . Bitcoin may not  design to last forever  but as  long  people  would  really use it and adopt it  it would  sure  exist  for  longer years for sure. About cars they are somehow  persistent  because   its  a common need  for us  in means of transportation.

Bitcoin, as we’ve all seen, is a mixed portrait; it goes up,
it goes down, it goes up, it goes down.  It’s hard to predict
where it will go. But I think bitcoin will last forever, or it has
a future since many users are in demands for bitcoin.

Yeah that two are are very far and different from each other but i will agree to some point on that cause even they are not related to each other the availability and sequence maybe connected in the means of existence and uses .its better to relate the situation than to compare on other things .

If you deal with the bitcoin as he needs to deal with he will last for ever off course but there are to many people who are still holding and dont deal with the bitcoin how suposed
so i dontt think he will last for ever.

I do think that Bitcoin wants to last for ever and because they have made use of the internet it can last forever but not sure if it will.
We will see how it is going to go with the Bitcoin in the future.

I dont think that the bitcoin will die sometimes but there will come a time for the bitcoin when the price drops that low that peopel dont believe into it
anymore and that is the time to drop the coins.

I dont think that the bitcoin is going to last for ever because lots of peopel dont think that is going ot happen because there will come some times
that the bitcoin is going to drop his value.

Bitcoin could last forever, as it designed so. Bitcoin demand so highly in the last year even there was hacked incident in this year, bitcoin could rise again. It has good foundation and advantages compare with any coins.

Yes, it could last forever provided the Altcoins market is sustainable and the Dark markets is still Dark. The BTC value comes from the demand for it from the dark market and also the Altcoin market has further strengthen the lead role of BTC in cryptocurency market

Miners will work for massive fees in the future which makes up for the lack of block reward.  loads of good videos on youtube about this.  and also nothing is designed to last forever.... :o

To last forever as a successful currency, bitcoin always needs some demand from citizens of this world.
Based on speculating the future electronic commerce, we are able to predict the future of bitcoin and its survival. 90% of future transactions will be done through internet, the fast growing of mobile transaction is a very good example for this. I too believe there will not be any problem for bitcoin to last forever.

I think that it is designed for forever but that it also needs more users and than it can really last forever, lets hope on that.
I think that the bitcoin has a great future and that it can accomplish this.

there is no expiring date on bitcoin, but this is the same with most other currencies. at some point the needs/userbase changes. countries rise and fall etc. most currencies do not last for more then 100 years. bitcoin however is not based on a nation or something similar, so it should have a longer life expectancy, however the things what money needs to be might change and this could put a quick end to bitcoin.

i think yes there is no doubt about this that bitocin is design to last for ever. and hope that it will really last for ever.

Nothing lasts forever, but if the internet stays the same and we will have some liberty in the future, then bitcoin should last at least our lifetime and possibly our childrens lifetime.

But eventually it will be replaced by a coin better designed, although I dont expect this in my lifetime, so i will remain with bitcoin.

Yah, it will definitely be a long run for btc but no one can promise that btc will still be around after 100 or even thousand years later. Maybe there will be more technology advancement and a better digital coin can be implemented with more efficiency.

Well maybe the name will stay around but it will definitely not be the bitcoin of today. I am not even sure if there will be humans by 1000 years, we will eithe have nuclear apocalypse or become cyborgs lol.

I think there are many factors to bitcoin could last forever, the first internal factors and external factors
Internal factors are users continue to use bitcoin and external factors is the internet continues to exist all the time

Nothing lasts forever, just understand that,

But that doesnt mean that bitcoin wont have a long future, it is just now beginning, and people already speculate about it's end.

So lets stop that, and we should enjoy bitcoin right now.

good point. is there a specific man made object that is in existence for a long time without change?
people will always speculate about the end of something, it is in their nature. everyday someone somewhere tell somebody that bitcoin will die and one day someone will be right. hopefully thousands will be wrong before that.

I dont think that the bitcoin is designed to last for ever because the bitcoin hass nothing to say for that you know there are so many users they will cause the bitcoin
his dead for sure!

I do think that the Bitcoin is designed to be forever because they made sure that the main thing was the use of the internet and that is never going away.
I do thin that there intention was to last forever in this world.

But, I don't think there will be any chances for internet to go down so that bitcoin may get affected. Bitcoin will last forever in this world as long as technologies and human are surviving. It means any abnormal events may cause problems to human race and bitcoins. Technically bitcoin will last for ever by solving its requirements and challenges.

Though we don't want it to get replaced or maybe it wont be replaced but it is also said that there is always chance of betterment in something, so maybe as you said some other coin or a currency will be generated in coming time with more better and unique features which might let bitcoin fall down and takes its place, because anything is possible.

one thing to have in mind is that forever does not mean a long time because it can be around for a very long time but not forever.

anything has some kind of expiration date and that thing is either going to change and adapt the new world in the future or it will die off soon.

this "thing" can be bitcoin or it can be any technology in the world as we can simply see by looking at the history and how many things have dissipated.

Bitcoin is just a data and you can't kill a data or physically destroy a data. Everything that has been posted on the Internet will be here forever unless permanently deleted of course. Bitcoin is just a data that is saved on the Internet. As long as there's Internet, Bitcoin will always be here and I don't think Internet will ever shut down because it's necessary in our daily lives.

Yes, digitalization and need of electronic payment system are emerging everywhere, so the demand for bitcoin system is keep on raising.

When there will be need of electronic payments for our daily life and usage, we never need to worry about the existence of bitcoin system as it will be surviving with its applications. Bitcoin has many advantages to suit almost every people of this world, so bitcoin will be used always by us for our daily life.

i think yes as you can see that people are entering in the world of bitcoin with their investment, and making bitcoin more and more stronger that is way we can expect that bitcoin will remain for ever.

I do think that bitcoin is mend to stay forever that is why making use of the inter was there because that is going to be around forever.
I do think that bitcoin is the potential to be around forever but if it will happen is something else.

when we will reach to the limit then no more bitcoin will genrate and then the increase in the rate of bitcoin will start and it will going on increasing because the number of newcomer in the bitcoin will came and due to this the no. of bitcoin per bitcoiner will became less this will results in the rise price of bitcoin .

No. But it can become the world's history. If something good will happen that every people will know about it and somehow use it then it can create a worldwide mark. But we dont know if that can happen.

Yes, nothing would last forever. Bitcoin was designed and expected to last more for another 160 years from this date. But if there are other factors that would hinder the development or replace bitcoin such as the potential threat of the quantum computers, bitcoin may possibly disappear earlier than expected. But let us not fear and continue to do bitcoin since if we stop now we will lose the potential  income that bitcoin offers.

yeah i think nothing is eternal in this world, including the bitcoin, I do not know what that reason could make bitcoin become lost or replaced. it's all still a mystery, but it is certain that nothing can be immortal

Only God is eternal. Everything doesnt exist forever. Though I think it will take longer before bitcoin runs out in mining it.  There will be halvig over and over again until the last drop of this coin. Years will be counted for it and that doesnt end with that. It will circulate like money that are printed out.

Yes, there is every possibility of getting another coin just like we have ethereum now but it will be very difficult to get another coin that will completely replace bitcoin in the next century. Take it that bitcoin is designed to last forever because until the end of your lifetime bitcoin will still be existing.

Andreas made a video a few days ago about what happens when block reward goes to zero.

As Bitcoin increases in value denominations multiply so that's one way it can last longer.

Overall it's typical that future actions by researchers / analysts would boost the performance + longevity altogether.

In all honesty it was built with the foundations which will exceed time itself so there will always be a way for BTC to last long enough, if not forever.

I am sure it is designed to last forever. but we don't know can it last forever yet.
It is all depends in the users performances and how they will react in Bitcoin and how long they will support it.

Yes bitcoin will last as long as we want it and hackers keep the system safe. Otherwise bitcoin will last as long as human being exists. Because there is no deadline set by Satoshi. As long as bitcoin network exists we we'll have bitcoin but if  all miners stop their system and if it happen then we should give bye bye to bitcoin. Well we have 740+ could so we could afopt those other coins

Yes bitcoin will last as long as we want it and hackers keep the system safe. Otherwise bitcoin will last as long as human being exists. Because there is no deadline set by Satoshi. As long as bitcoin network exists we we'll have bitcoin but if  all miners stop their system and if it happen then we should give bye bye to bitcoin. Well we have 740+ could so we could afopt those other coins

I wonder ho can a hacker keep the system safe?  Anyway  I think bitcoin is designed to last forever.  It is a digital stuff that can be redesigned, upgraded or developed according to the needs of the current situation.  In short as long as people are supporting its economy and development bitcoin will never die.

if anyhow we can solve the total coin limit problem then this will be our second problem and i think bitcoin has every needed quality and features anyone needed to run a servic or a buisness bitcoin is just like the handy money just it is not physical its vertual but a lot more effective than faint money

I agree, there are some practical problem with electronic format currencies compared to faits. Fiats are always ready to use whereas electronic currencies are basically requires internet connectivity.

But, I strongly believe there would be many enhancement projects that will ease the complications of using electronic currencies. One of the solution right now we are having is bitcoin debit cards to use wherever we want at an instant.

Bitcoin to last forever, there are many possibilities and lot of supporting things are keeping on happening.

I assume the thinking is that it could last for ever or at least for a very long time. The problem I see (other than running out of coins to mine) is that there are coins that have been lost and can't be recovered. And there will contiunue to be more coins lost. At some point, there will be more lost addresses than in usable addresses.

Yes, i think that bitcoin is designed for forever. Now in this time, i feel no time to end for bitcoin, because in everyday bitcoin is going up and also we like it because bitcoin is good for all of us, and when bitcoin born and now in this time bitcoin never let us down, So all is well about bitcoin that's why i wish the day will never come when bitcoin die.

i think no if bitcoin keep stable, but if bitcoin can follow current development may be can forever..

When the system is keep on being used, we can assume it will last forever. Only not being used systems may go absolute. Bitcoin is gaining more popularity daily with its fluctuating prices and as convenient payment option. Bitcoin will definitely last for ever.

Yes it will last as long as we human want to use it. I is not installed and managed from one computer but juts distributed over all the computer that are connected to the bitcoin network so if one system fails then other will take the task to next level and if all the system fails or shut down simultaneously then only bitcoin will die.

There's no right answer of that question because bitcoin will only depends its user or to those people who use bitcoin. If people continue using it then developerswill continue developing it and to make it much better and to improve it.  But if people stop using it then bitcoin will be vanished.

Yeah! you are right! If no one is using it! then it will be gone! The thing is all the stuff in the world if no one using it then it will be gone or it will be useless and no one will use it but if the demand of it is still high then lot of people effort to make it nice and more effective and effort not to kill it.

The planning for bitcoin was a great one the inventor decided to introduce another currency which will be used for internet transactions and now we are looking that the use of bitcoin is even in some offline uses and people are shifting their businesses to digital world for starting this coin so from it we can see that it is more stronger.

yes it can last for ever, but i i think it also depend on the people interest, if the people interest in bitcoin is increasing then they will give preference to it and will use it and the second is that it also depend on the interested of the government, if government allow it as a currency to be use in their state then people will get confidence and will practice it and bitcoin will survive.

yeah I agree with you that might someday bitcoin will die and may be replaced by a currency or other crypto but maybe cryptocurrency may also be dead, no one will know the reason, but I'm sure bitcoin will not last forever dude. everything has its time, and if those days are finished of course, it will die

I think bitcoin was designed to be used in a long term, but not for last forever because nothing is immortal in this world anyway.

well I don't even know what satoshi thought when he created this thing, but there are many possibilities we don't know to happen in the next few years.

I am not agree with you, just think by your logic, People interested with altcoin becouse they was know about bitcoin first. also they still thrust to altcoin becouse they know that there is the first of crypto currency is still life and usefull. just think if bitcoin is die, people who know this news will begin to not thrust with any cryptocurrency. Don't you Understant that bitcoin is like father of all of altcoin. I realy Sure that bitcoin is not just being a history but it will uses forever. becouse we are always keep moving forward and bitcoin is the future.

I strongly agree with  you  nothing  in this   world  designed  to  last  forever  but  for   bitcoin i could say that  it was created  to  last  long for  more  years  because  people do  tend to  use and adopt  it  and we could really say that  it  would  stay   on longer  years. As  you mentioned we  really dont  know  on  what  is  on the mind  of its  creator Satoshi and  its  devs  but  one things  for sure, bitcoin is  very  valuable for us not  only  on  earning  opportunities but also to the  benefits that  it gives.

Yeah, bitcoin is like foundation of cryptocurrencies world which has good development since it has been made by Mr. Satoshi.
We don't really know about it's future for sure, but I think it could last fo a long time and compete with anothers altcoin.

just because bitcoin is a stunning new technology and some say even a miracle it does not mean it is indestructible. remember the titanic? i bet people where also talking about "is titanic designed to last forever?". we live in a world where a currency seldom lasted for more then 100 years. and technology nowadays is changing fast. it would be a folly to think bitcoin will be here forever.   

Yeah I supposed bitcoin was designed for a long term usage but not design for forever, as we can see Satoshi is only limited the bitcoin 21 millions bitcoin, so if all of the people in the world used bitcoin then the amount of the bitcoin won't be enough, so while you still have the chance, you need to make good used of bitcoin

That is certainly true. But if you look at the number of bitcoin that much less of the population of this world then I think that's something inappropriate things to think about. Because if everyone is already using bitcoin, then automatically price bitcoin will be higher because the overall number of bitcoin is much lower (Economic Law), so this would be a great advantage and not a problem

I think as long as internet still alive i believes that bitcoin will continue to survive because its the only one who can make bitcoin die and stop operate is the loss of internet connection, so as long as the internet is still alive then bitcoin will continue to live :D
I do not think there is another reason that could make bitcoin die

Bitcoin being a code that is open for improvement and upgrade simply means bitcoin is designed to last forever.  with the updates and development, bitcoin will have its usage and importance retains thru out the course of human history.  Unless the developers give up and no one to pick up the development then that will be the time bitcoin will become idle.

I think it will be all about after everything is mined. But I dont think we are still alive to see that. There is a lot to be mined and halving's will come creating less mined coins. So if the support will not end until that time and new generations will be enthusiastic just like people in this community then it wont be a problem to last for a long time.

for me bitcoin is seen to be a financial media that can be used in a very long time. could be in the future bitcoin will have a unit price satoshi. along with the rise in the price of bitcoin on the market.

Bitcoin already did proved that it last longer than other crypto currency. Yes it is still profitable for its miners because it is getting some fees to sustain its miners but in the question that  bitcoin was designed to last forever i think that it is not it simply wanted to have some medium of payment online and this is still experimental

Some day all bitcoins will be mined. That would mean no transactions will be confirmed anymore. I think that coins can still be sent, but without the confirmation, I don't think that people will still use it. So no, I don't think bitcoin will last forever. Besides, I think that the confirmation times will become so slow that long before the last coin will be mined nobody will use bitcoin anymore.

Yes.
Bitcoin is deisnged to work for ever as long as the community keeps in supporting it.

But in 50-60 years,when we would not have any block reward,and the miners will earn their salary from fees only,we will need a large amount of transactions.

The only thing that keeps bitcoin back is the block limit,which we will need to solve anytime soon.

Yes I believe, to last for ever, all possibilities currently bitcoin having, will be more than enough.  Also there are also many enhancement and developments are happening around bitcoin system, that will certainly help this system to go stronger will find its way of existing with us for ever.

Bitcoin was designed to last for a really long time, transaction fees will probably keep miners well fed as i presume bitcoin will be widely used by then.

I actually think that it will take many years to reach that cap, in fact i don't think that we both will be alive then ( unless something changes ) but it won't last for ever, just for long time

Nothing lasts forever as new technology grows and other events happen but if all goes as is going now I think Bitcoin can last a very long time and may eventually EVOLVE into something else, but it has started a new digital revolution for this generation that's for sure.

Bitcoin as a form of currency and as an advancement in technology is developed with certain time limits as most users quoted. But things gets changed when people start accepting it. On account of this technology might be developed to last long than the previous limitations or the same gets into existence in some other form.

I agree with you , nothing  really last  forever and  shall passed away  its  either  been broken or  just  normally passed away  but   in the field  of  technology  , i could  say that  bitcoin is not designed  to last forever   but  im somehow assured  that  it would   took  up for  many years  before it would  gone because as  we all  witness now  that  bitcoin  is   already being  adopted  by people   and  increasing  as the days  goes  by and this  indicates  it would  last  up, bitcoin would end if  no people would  tend to use it anymore.

Time will tell and its the users will make it possible with so many adoption and so much earnings coming from this investment many interest has been gathered so we really cant say if btc can survive forever but hoping that it continue to works the way its working right now.

this question make me scary now ???
but i think we still can use bitcoin for this decade

This is philosophical question, probably every creator or designer have a wish on beginning to his work live as longer as possible. But can something last forever? Nature around us says that everything has an end, bitcoin as technology will have and can have much longer life then things from nature.
As a man who have faith in bitcoin, I think bitcoin will last very long time. For now bitcoin have 7 years behind, and when we look period of 100 years bitcoin is still very young currency. We will see how old bitcoin can be, and will something younger and better will replace it one day.

Interesting question!
I think that the duration of btc depends mostly on how people will react to it over the next few years.
If the majority of people will continue to feel skeptical about it, btc use won't spread.

I wonder if something better than bitcoin would be made in near future, maybe someone will do it later on but still i feel bitcoin would be used as an alternative if its price still stays high.
And as you said, everyone after making something wishes that his thing should be too successful and to be used forever, but that may don't happen or it may, because technology is something that can stay forever until the world exists and bitcoins is a technology.

Time would   really  can tell because we wouldnt  know  on  what would be the future  of bitcoin on  upcoming years  to come, it might  been  adopted even  more  or  it would fade  away easily but  as we can see  on  bitcoin its  already  building  its  reputation  and we could somehow  say  that  it would  last for more years  to come.

ofcourse , it is made for forever because we see that there is no limit of creating account of wallet and no limit of create new btc adress .
so these qualities indicating that it is made for forever without limit .

I don't thinks it's a philosophical question, is more like a technic question... And yes, bitcoin is designed to live "forever", the mining system if "perfect", it will rest 100 years and after that miners can profit with fees that will be bigger. The major problem with bitcoin is their users, a lot of scammers trying to take some advantage.

The only thing that could prevent it from happening is a big fall in price for bitcoins which  make a large amount of miners to leave and may cause transactions not to get confirmed which will make the price even lower and may cause the community to lose trust in bitcoin which can lead it to a big fail.

Well No one knows if it's designed forever, Only Satoshi himself. But I think that even if the 21million btc's has been mined as long as there are many people who uses it, then it will not be gone.

No such thing that will last forever but I am sure bitcoin is designed to last forever and we will be the one to make that happen.
We have to trust bitcoin all the time so we can continue to make this a success and hopefully will last forever.

nothing will last forever, and anything that has been created so far and will be created in the future will have an expiration date. this can be 1 year or 10000 years from now.

for bitcoin there is still a very long time to go, most possibly more than our lifetimes.

Like other currency which doesn't have any deadline bitcoin also have no deadline. It would exist on this planet as long as human being want to keep the network alive. Bitcoin is fully depended on its network and if something happens to the bitcoin network then we might loss all our bitcoin forever

Thanks OP for asking this question.  People are finally starting to ask it and to think about it.  This will be an issue long before the last coinbase satoshi is handed out in 2140 because bitcoin's distribtution curve is a rapidly converging geometric series.  Already more than 3/4 done.  

As you know if you have looked at woodcoin, there are ways to do coinbase distribution without rapid convergence, and without infinite inflation.  

But lets look instead at the possiblities for what happens to the original bitcoin around 2030 or so when the coinbase reward drops below fees:


1)  Mining Centralization.  This is the NXT model.  Fees stay low but miners keep mining at high security because they hold a lot of BTC and want to see BTC still work so that their coin will hold its value.  I find this hard to believe but it's a possibility.    

2)  Large Fees.  This is how Satoshi said (briefly in passing) that it would work.  Security against double spends will be paid for by large fees on transactions.  As long as not too many people flee to other coins and they stick with btc (at this point solely because the market values it highly) this could work.  The network becomes a high-value-tx network only, as transactions on the scale of a case of beer simply won't be able to afford to get into the blockchain.  This is what most people envision; there is some stability question from a game theory perspective though, as users wishing to use coin for small tx will flee to other coins.  

3)  Coinbase Adjustment.  This hardfork is sacrilege to suggest at this point and I see 0 chance of it happening.  However to make the list theoretically complete it should be here.

4)  Pro-bono mining.   This also seems quite farfetched, but you never know.  People might just mine the thing because they love the community or some such.  

5)  Flight to other coins.  There could be a more stable and robust diverse public coin ecosystem at that time and markets will evaluate coins accordingly.  My suspicion is that it will be more complex than I can predict at present.  

      

Seems like number 1 is contradicting number 2 about the low fees then large fees? Or is it just on a different timeline? Are those different fees you are talking about? Just asking.

Yes, those scenarios are contradictory.  I'm just trying to list ALL the different things that could happen.  

i think yes. bitcoi will be live till we trade it. demand and suppy will decide the validity of bitcoin and i donot see any stoppi or brake in the path ever even banks can not stop this nor governments

Yeah, bitcoin currency has no deadline, So it has clear mean that bitcoin never going to be end, it will be live long till the end whenever we are using it and investment with it and earn from it. Now we can say that bitcoin has a bright future, but may be in future, suddenly something will be wrong with it, and bitcoin give us big circumstances, or may be bitcoin would be converted with another crypto currency. But that's all are thinking, not in reality, now bitcoin still going up and better and useful for us, so 100% chances bitcoin live long life.   

Possible or prediction that we do indeed something reasonable thing and it will give you a pretty good effect if we could deepen the prediction is done or heard or read. I was also so, that I am sure that bitcoin will become the largest physical currency and will be most widely used by everyone because of the nature of the benefits and not owned by any existing currency. So this will be a very great thing

Bitcoin will survive alive as long as possible
Bitcoin users itself the only thing that can make bitcoin last forever or dead very soon
But i believe satoshi itself not sure about what will happened to bitcoin in the future
So there's no something called 'bitcoin designed to last forever

I am pretty sure bitcoin wont last forever. Everything we see is temporary but as long as bitcoin is still in operation let's make the most out of it.

No nothing in this world can last forever include bitcoin, but the good things about bitcoin is decentralized, so if there is still transaction and pump and dump, bitcoin will stay alive, but when people dont't used it anymore then bitcoin is dead

Yeah you're right, nothing lasts forever even this planet won't escape from extinction so just enjoy it while you can. But I think when this all ends, it'll be long long after our grandchildren's death so it's not necessary to worry about this problem now.

Its true that nothing lasts forever nor bitcoin will, but as you said until it is there we should not waste our time thinking about these things, but we should enjoy the freedom it provides and we should make the most out of it until it is alive and running and i feel the period of bitcoin being alive would be really long by looking its potential growth.

I so agree with your statement about not wasting our thinking about these things and enjoy bitcoin. My opinion too is we should all be well aware of when it's going to end but let's enjoy it for now.

how by fiat? where if the government in power they will certainly maintain it until whenever. I'm sure fiat will continue to be used until Judgement. I might say that bitcoin will continue to survive if all users continue to use whatever happens and continues to believe, then as time went on and the growth of the bitcoin users in turn will continue to persist for the entire user trust in bitcoin

Is Bitcoin designed to last forever?

No it is designed to last until you run out of Fiat.
Electricity drain will make it unsustainable & unaffordable in a few years.

Bitcoin was started as a project which turned out to be a revolutionary concept in crypto currency technology. No one can tell how long bitcoin will last but in future I am sure the payments will have great impact of crypto currencies and any other alt coin can replace bitcoin. Probably in next 5 or 10 or 50 years, no one can predict accurate future but right now we should concentrate on bitcoin because down the road it will guide the next coins.

after 4 5 halving there is significantly very less number of miners. now itself bitcoin mining is Less profitable and after 4 5 halving obviously there well be negligible profit. and many miner will quit mining bitcoin and will probably switch to other altcoins. So i think mining of 21 million bitcoin will continue as long as our planet exists. hypothet in my view.ical situation

Forever is a long time and I don't think when people design something they expect it to last forever. Eventually something new will take it's place.
I guess a newer version of bitcoin could eventually replace the current one.

It will be replaced by a newer version but we don't know if there would still be a better payment method or currency than bitcoin. Among all the other crypto-currencies, bitcoin stands out. I am not sure, though. Because back then, when we're still at the barter system, we didn't even know that fiat would be the primary way of paying somebody. Years ago, we didn't know that there would be something better than the fiat -- it's the cryptocurrency.

Bitcoin possible to last forever because as of now its demand is high.
And many users are currently in touch with bitcoin because this gives
an extra income. Before we dont know that fiat could exchange to other
currency, but since bitcoin was become popular this could be possible
to last forever.

we will never know about the future, because the future is another mystery. if the entire bitcoin in this world only reached 21 million spread. it's good to be grateful for the existence of the current bitcoin. if keberadaa bitcoin has run out someday, it might take very much time to spend the entire amount of existing bitcoin. so this time we should be grateful because we can still get bitcoin. ;)

Bitcoin can stay forever but it is going have some serious forks to it. The energy drain is considered as a serious problem and I feel fork will be made in future to the code or make it , what can I say, more energy efficient ...We can expect shifting it to POS. In future, we can definitely expect new changes and innovation being made. This will have an impact on bitcoin and bitcoin mining.

That is the weaknes of bitcoin. Anyway, By this technology we can send money to anywhere that have electricity and internet connection. And I think probably we do not spend too much electricity for bitcoin. Satoshi nakamoto is one of genious people that make a change of the world. although bitcoin did not have intrinsic value but fiat is just paper, both are the same but bitcoin is have so many advantage, like fast transaction.

yeah I agree with you that all things will not last forever, including bitcoin. I think bitcoin has a lifespan and could possibly die
but as long as users continue to use It so bitcoin will continue to live

Bitcoin cannot last forever, because of the 10 minute block time, it means all nodes have to be within 10 light minutes.  Mars is outside of that range (it varies between 4 and 24 minutes).  You cannot have bitcoin miners on Mars and on earth, because a block mined on Mars could not reach miners on earth before they mined the next one, and vice versa.

As the earth will be swallowed by the Sun turning into a red giant in about 1 billion of years, that would be the end of bitcoin too.

Hence, bitcoin cannot go interplanetary and certainly not interstellar and hence is doomed to die with the earth, even if our species or whatever is living on earth can leave, it cannot take bitcoin with it.
 

Nothing is permanent, even something as popular as BTC. Also, the amount of maximum BTC that can exist at any given time is set at 21 million, so if it reaches 21 million, BTC will lose/gain some of its value, but it will soon go out of circulation as the production will be stopped. Also, it can be banned by a country and it could lose its popularity and die. But, yes, it is unlikely that BTC will ever lose its popularity.

I very much agree with you. But everything you say or think is not always true, for a future we cannot guess easily. Because all the things that are in the future is the will of God, so that we can only see and enjoy it. BTC is not something that can be missing from circulation if in the future growth of the bitcoin's getting good or stable while all total BTC completed in mine.

No one will last forever in this world but, if in my own opinion with bitcoin i must say it will last longer but not forever. As long as many people believe and will use bitcoin this cryto currency will have long life i could not say specific life span but it will live longer in the circulation of the internet world. Go bitcoin and soar high around the world as our hope this will last longer for so many years.

No one  could really  predict  the  lifespan  of  bitcoin since no one  could able to  predict the future. I agree with you it may not designed to last  forever  but  it would surely last  for  longer  years as long there are people who  would still use  it  and  as  we all know bitcoins  adoption  cant  be stopped and with this   it would  make  bitcoin more  stronger than before and  would established.

It could happen .because most media payments are not designed to last forever. because there will always be updating technology. there will be a replacement for bitcoin, but for now bitcoin is a revolutionary thing.

That is right. We cant stay of what we are now bevause we are getting populated. We need a faster transaction that can deal with a bloated problem when it comes to money. Sending money, online transactions, paying bills and a lot more. We want convenience and bitcoin is offering that.

Well I think that bitcoin is designed to last forever because of the updates embeded on it to be more accessible for future updates.  They maybe some new technology ahead but I think bitcoin will evolve as technology get updated.  There is also these people who are dedicated in Making bitcoin up-to-date and can give the demands of its users.

Bitcoin may be forward compatible, but its longevity is decided by the users and demand.
No matter what the technology is, if people are not convinced, then it is useless.

I do not think bitcoin was designed to last forever. It is just impossible, nothing last forever. In our time technologies change one another very fast and this process are getting faster and faster year by year. So I think bitcoin will go in past one day as well and that may happen not in a far future. Now bitcoin is kinda on the top of it's development, but after getting the top always are following the fall. So it's just a question of the time.

Bitcoin mining system were made to last several years, and now there is a timeline around 2100 where all bitcoins should be mined, after that the current system should move into fees to pay for the hash from the miners, or something strong. Some countries has banned bitcoin but hasnt affect at all the popularity, in fact those action has made bitcoin more popular.

It's designed to last forever or by the time we could have internet in the world...

Without internet and informatic, BTCs don't have reasons to exist, as it's a digital currency and only exists on the virtual world. If nothing goes very wrong with the world and the humanity, the Bitcoin can last forever for sure or at least its essence (the technology). At determinated point, this currency can be exchanged into another and don't exist anymore.

probably not it seems like the more andmore people joining the network and in future it will exceed the limit i do not expect to see what will happen then. there are only 21million btc in the network and they are not fully mined till now.

I'm here waiting for someone make an song like: "Bitcoins are forever"  :D :D Hope it can make the price goes up.


What's the problem with 21 million? we have 8 digits after

agree future will always be a mystery, and there will be no one who knows the future of bitcoin will happen. very probably bitcoin could speak more in the future and it is possible that bitcoin die "if all users leave bitcoin" therefore bitcoin is not made for last forever dude. #imo

For bitcoin to last more than another couple years, transaction times need to be greatly improved.
This is the biggest drawback currently, in my opinion.

If we can get fast transaction times Bitcoin will be around a long time.
If another cryptocurrency can come to market with similar features and provide near instant transaction times without relying on a third-party application, it would definitely have the potential to replace BTC as the top coin.

Nah, it was to last a few years for a quick cash grab and that's it, of course when bitcoin was launched it was to be the idea of crypto currency and being open source then generations came after by copying the code or and learning from it.

Bitcoin is more of an innovative idea by the people and for the people.

can you see at your statement that it's indicated how precious bitcoin will be ?
a limited supply of bitcoin will make bitcoin itself rare
and when there is a lot of demands the price will be up as hell
regarding the invention of bitcoin noone will know about it , only time can answer it for you.

While having more coins in the system devaluates the other coins the truth is that the rate at which the coins are mined is slowing down and the price does not seem to be affected bi it so I will not worry at all to have the 21 million coins in circulation.

there is no one who knows what is the future of bitcoin we only need is to believed that bitcoin will last forever and it will gives us more money in the future, that is why we need to help to promote bitcoin to other people to make the life of bitcoin stronger.

I am not thinking the original design will last forever, however I do think that the upgrades they will make to it as it moves forward will assist in it lasting for some time to come.  The way it sits now, I do not see it ending in my life time.

yes i think bitcoin need for us to introduce to the public, its purpose so that bitcoin become a major commodity in the life of society, so the more powerful in existence. and when the bitcoin has reached retirement due to stock 21 million bitcoin has run out in the future. possibility could be updated to become more and more. :D

Will bitcoin be around forever? Assuming 3 people in the world are running a node, yes. Is it always going to be worth something or as much as it is now if not more? Who knows. It's the first cryptocurrency so I'd have to assume something better would come out in the next hundred years (give or take;)) making bitcoins obsolete. Or it coin will just continuously evolve.

We don't know but we can know if it is going to be on a long road map. And that is going to be determined by us if it is still on its way for the future.

But if we will base on what is happening with bitcoin today, I can say that its designed to be used everyday and depending on the governments adoption.

And basing on the bitcoins price increase, we can tell that it can be on the market in the long run.

As we repeat, as long as there is community or a group of people supporting and trusting it, bitcoin will never be gone. Its existence is depending on us who are using it everyday. If we find it not useful anymore, I think it will ceased to exists.

Exactly, we the supporters who are giving life with bitcoin and as we see the price of bitcoin is growing it also reflects to its users. There is no doubt that the users of bitcoin are also increasing because the price is not a manipulation as we have witness now.

I also think that bitcoin is not designed to live forever, bitcoin risk to die when the price becomes zero, so it can be proved that bitcoin is not designed to last forever

It may not be designed to live forever but if we keep on using it then it can live for a longer days. A chance of making it to last forever is really high because we are in modern world and we are using modern technology. Transactions will be online and digital and bitcoin will be the medium of it, only if the world government will recognize its goodness.

Bitcoin will last for years, because it solves problems that other forms of payment have.I don’t think that bitcoin will disappear.
As long as there is still internet there will still be bitcoin.

If the support stays, I'd say Yes.

You think bitcoin can continue to grow and change according to the times? if it can be done. then bitcoin will continue to be updated and there will be no other altcoin. which could replace bitcoin, and bitcoin will continue to survive

definitely right,if bitcoin could just evolving by the time and always growing to be better coin it will for sure last for next hundreds year but a new developed technology always coming out and threatening bitcoin's place as the main cryptocurrency right now and if one coin just gaining the trust from bitcoin users and could even make bitcoin users moving out from where they stay,bitcoin will potentially lost its daily traded volume

Good point. Nothing last forever except Change. So, when they change or upgrade Bitcoin, maybe it can last for a long time. Although time will come and halving and halving occur and the miners will get smaller rewards in every block. Which will cause them to leave mining and Bitcoin will be dead gradually. But, the developers can create another version of Bitcoin which can save the death of it. Just like ETH. What do you think ??

That is not true,we  do not need a change in order to make bitcoin last forever.
The current network system works good,the only problem is the block limit,which pretty much hurts the community and the miners,but the whole system is being trusted by a lot of people so at the moment we do not need any change to make it better expect of the block limit.

I do believe the bitcoin can last forever if the community will keep growing to increase the bitcoin price and to make it worthable for miners to keep mining bitcoin.

Bitcoin is a result of technological innovation. While the payments industry will also change rapidly with technological innovations which provide benefits in the medium of exchange that is better than the cryptocurrency. This innovation will could have come from the government or from the private sector. On the other hand there are other factors that also affect the monetary standard Bitcoin. Namely the pressure to return to the currency Fiat. So that monetary policy will be more active and can catch up.

Yes, it can survive for a long time. As long as many people still supporting bitcoin, it can last forever for sure. But i think many changes will happen every years passing by. Because in the future, technology will be more progressive. Bitcoin needed to adopt in the innovation in able to survive.

I also think that it can survive for a long time but I also think its hard to say if it will due to the fact the bitcoin is unpredictable so no one knows.

as long as we use networks and computers there is no reason why we could not use it for a long time. i would guess that the computers will get obsolete before we stop using bitcoin, so we will have to adapt it.

If you can convince the miners of the few that hold the blockchain nodes in 20 years if it gets too big to move to clean chain this can easily be done in a exchange 1 btc for 1 new btc.  Then after 2 year period all btc on the old chain will be invalid and the chain is shutdown.  Thus you have a new clean chain.

You could also tell everyone to spend their coins in 1 year.   Then the entire chain older than 1 year could be truncated (there would have to be some software work).  Thus, you would not only have a young chain you would know exactly how many coins are left in circulation.  I would say 1 million are already lost.

As for all the new and alt coins, they generally all suck.  There is only one alt-coin that might be better than bitcoin and that is say you buy into the coin and generate $1 billion cash. If that cash could be used for investments and the profits used to delete coin, then you have a coin with a decreasing money supply.  A decreasing money supply will make users richer and increase adoption.

Thus if the money supply drops from 21 million, 5% a year you have 2 million or so after 50 years, thus your money is worth 10x and that is with no new users.  With new users that might be 100x or 500x.  That is adjusted for inflation so you invest $5000 when you are 20, you would have $2,500,000 when you 70.

a technology like computer will not get obsolete in the future
it will keep developing transform to something great more than just a computer and an internet
bitcoin come to make everything perfect , and i don't think bitcoin will not fit to the future
and of course i believe bitcoin designed last forever , hard to make it dissapear.

I do believe bitcoin has found its place, and its king of crypto currencie, i dont see bitcoin allowing any other altcoin to replace it, how long bitcoin will last is easy, as long the community keeps interested into it and use it, otherwise bitcoin can fail badly.

Yeah, its exactly like that. Bitcoin by design is not beign safe/ could last forever or nothing like that.
People make it so. As long people will use Bitcoin, people will develop it more, secure it more, make it faster, better etc.

But that applies to any other currency, when a currency has a value of zero that currency is useless, but I really think that since bitcoin performs a function that no traditional currency has bitcoin has the possibility to outlive them even if eventually a new coin appears.
