Have you ever wondered how the future of crypto land will be once all Bitcoin are mined by 2140? By that time, Bitcoin miners will be living off fees. It's expected that Bitcoin's price would be high enough to help sustain miner's operations. Bitcoin could be well worth over $1m by 2140, if all goes well. There will be a lot of demand for altcoins as digital cash, while Bitcoin will be the world's store-of-value asset. Scalability and privacy may no longer be an issue within the Bitcoin blockchain, as developers would've found a way to make the pioneer cryptocurrency useful for the world.

While we still have a very long way to go for this to happen, it's great to imagine how the future of Bitcoin and crypto will be after a century since their inception. I'm curious to know what do you think Bitcoin's future will be after 2140? Your input will be greatly appreciated. :)

Since we are talking about 2140 where i will be long gone from the face of the earth and if my presence in this site and BTCitcoin can be seen as my foot print of existence it will be my ghost  :D, i can dream about sending BTCitcoin for a few pennies by that time and the miners will be living off the fees and without incentives they will not be sticking around for a long period of time and for that to happen i am expecting a revolutionary scaling solution by that time without expecting the price to reach a million dollars.

With all these expectation and the financial freedom we have, i hope people will have the same kind of freedom we have right now, considering how every movement is captured by the authorities and with the corona crisis each and every footprint of every individual is monitored and i hope they will stop doing that after this pandemic is over.

as @eaLity said, I am also gone by that time.

That's over a hundred years from now, it's really hard to imagine what might be the value of bitcoin by that time but for sure, its value will be something different from now. Bitcoin will surely be adopted from different countries and legally used to do in different transactions.

I have read a ppst by Satoshi which was something like "In future, BTC will either be huge expensive that people can never imagine, or it will just die." I also think that way. If BTC will not become so expensive in future, miners will not just maintain the network as charity. However, we are talking about more than 100 years and I doubt BTC would exist such long times.

From the previous year the market price of the bitcoin is just ignored by the people because it looks like a less than dollars but today the price of the coin ate rapidly increasing and giving a good market value of the coins and now we are seeing the volatile of the market and in just a single month we saw the market price of the coin falls down but because of the volatile it grows up immediately and recovering back to it's highest market earning which is a good thing and gives a huge market income

I think the market price of the coin in the year of 2140 is already exceeded on its market price today because the halving is already reached the block required before on that year IMO I think it has come over 20 dollars but still this is a dream for us.

Perhaps Bitcoin is dead or there is still a way to survive. But I like your logical way of thinking. I also think there will be new technologies that will replace Bitcoin when it is fully exploited.

Bitcoin mining will become unprofitable probably a 100 years before that, so what you say will probably be experienced in our lifetime. This does not mean higher demand in altcoins, Bitcoins are scarce and thus more valuable. Just because you don't make money mining bitcoin does not mean it loses value, most of bitcoin's value is unrelated to mining (contrary to some beliefs). See after each halving bitcoin mining profit gets cut, as it was designed to, and the same happens to miners, because it is a transition to the stage where most bitcoins that there ever will be already exist and no more are coming (or take so long to come that its pointless to wait for them).

As i keep telling people, bitcoin price isn't rising to compensate miners. It does go up, but at a lesser rate than mining. Mining was, since the beginning, a temporary thing. Those that made models thinking mining will remain forever, where wrong since the beginning. You can't possibly expect endless mining with a coin with finite supply, this is how flawed that thinking is. But unlike an abrupt ending, the halvings make for a a smoother transition. Miners have the chance to plan their exit, as many have done.

Sooner than later, the only mining will come from hobbyists and those with "free" energy. By then the hashrate and difficulty would have gone down, but since its unprofitable anyway most won't bother. Bitcoin will go on just fine, of course.

My view about altcoins are contrary to yours. There are simply too many, most are destined to die. And people are not going to bother carrying 100 different types of coins. The only thing that matters in the end is: Can it be exchanged for bitcoin? And that is that. If a second or third altcoin manages to survive and get used, it would be a miracle.

I have warned miners before that the time to diversify or even venture into other business with the money they got from mining is now, and every day that passes, if they don't shrink and switch they will end in the red and lose all.

2140 is a long time in future. None of us would be alive at that moment. And it would be quite absurd to think about economics at that time.
If I were to imagine, economy would be a whole different from what we have today. The society and the systems would too be different.
Imagine 1900s and where we are now. Similar would be the difference now and in 2140. And I don't think bitcoin would be perceived and trades as it is at that date. We may be keeping the coins with us as an antique but I don't think we would be trading them with value.

I expect trilions of market cap at those times

I think he (BTC) will not die. Just look at blokchain being a solution in various kinds. Blokchain cryptographic systems evolve with growing needs and times. I am very sure of that. But maybe I didn't arrive in 2140, maybe my grandchildren.

it is hard to predict bitcoin after so many years. but if we put basis on its price chart we can really see or notice that the bitcoin is always rising, it will rise and sometimes fall but it does not return on its starting price from year 2009 so I believe that after so many years bitcoin will become more amazing.

To move on in 2140, it seems that we will never know, maybe our children and grandchildren will find out about Bitcoin in 2140. Now all we can do is predict Bitcoin in that year.

Maybe Bitcoin will be the most valuable asset in the world as the best digital asset, because the development of technology is now increasingly advanced with an increasingly widespread internet media.

The developers will continue to develop Bitcoin, Blockchain and cryptocurrency technologies to be better and more flexible to enter the world economic system.

Everyone who is in the cryptocurrency world wishes the best for the future.

It's impossible to make any kind of good prediction for such a long term. People can't even predict Bitcoin's price, adoption level, protocol development for a few years ahead, and you're asking about 120 years. There's a solid chance that Bitcoin will no longer exist by that time. Maybe it will fail to get adopted and everyone will lose interest, maybe there will be an entirely new technology for decentralized payments, or maybe we'll have a nuclear war that will destroy the internet. Or maybe Bitcoin as we know it will evolve into something much bigger, just like computers evolved from huge boxes into pocket-sized gadgets. There's way too many possibilities, especially considering that Bitcoin doesn't exist in a vacuum, it relies on other technologies like the Internet, computers, operating systems, data storage. They will change a lot in 120 years.

I can not imagine that how bitcoin miners will be able to survive based on transaction fees. I believe bitcoin will increase in price, and maybe it will reach a very high one in 2140 but as a very normal growth, bitcoin transaction fee should be cheap and as cheapest as possible to increase its adoption.

The only one thing I can imagine of is a very good adoption of bitcoin in 2140, and miners can make many transactions and earn fees from them. Maybe it will be supported by some future protocol changes.

If someone does not find a way to allow us to use Bitcoin in the afterlife then what will happen in 100+ years falls into the realm of science fiction.

Joking aside, it is impossible to predict the future of anything in the next 100 years, because people show almost no signs of common sense (with rare exceptions) when it comes to the survival of mankind on planet Earth. The fact that we are relentlessly wasting resources to the point that they cannot be renewed does not guarantee us a very promising future. Earth Overshoot Day (https://en.wikipedia.org/wiki/Earth_Overshoot_Day) is getting earlier every year, which only speaks in favor of the fact that people are not quite as intelligent as they seem.

No one knows what will happen tomorrow about bitcoin, I don't know if Bitcoin will ever live for that year as well. If ever Bitcoin survived until that very year, I am sure it takes many leaps we could ever think of - maybe a single satoshi is worth as a fee for a transaction and many more.

I am thinking dollar and other fiat currencies have been discarded and people are using crypto as its sole money paying for services, goods, etc.

Well, I agree in the part of bitcoin's price change by the year 2140 but to be honest I'm getting a little bit skeptical with regards the adoption. I say so because even in whatever timeline we are, government has a consistency. I mean, it was handled by different people over time but the way how it goes is the same. What I'm tryimg to say is that if your country hates the concept of cryptocurrency today then most probably it remains the same in the year 2140. Nonetheless, I am hoping all the best for bitcoin. I hope it will not take that far either for us to ach3 our dream of crypto revolution :).

I believe whoever active on forum currently will never live till 2140 (not sure, perhaps any lucky man would live), so it's quite complicated to imagine as well. Simply when bitcoin has created then no one had expected that bitcoin could reach $20K on 2017. Same like we don't know exactly what will happen, perhaps bitcoin would replaced with some new technology and it will not exist. But to be honest if bitcoin exist upto 2140 then I am not worried about miner fees. There is huge potential that price would increse out of our imagination. Then transaction fees would be enough to genarate revenue for miners since bitcoin  adoption continues.

With bitcoin's uncertainty during these times, it is harder to predict for its future and talking about more than a century we are all dead by that time. We can unsafely predict what bitcoin could become after 2 to 5 years of its existence, we even have several governments opposing the bitcoin. But I'm wondering for that long time, if we are not dead yet, are we going to discover better currency than bitcoin I mean we are testing many lines right now so maybe we are just too focused on bitcoin coz it is a thing now.  We can't really tell no?

^ Bitcoin in 2140 may or may no longer exist by then but one thing for sure all of us here are no longer alive on that year since that is too far from now. We cannot predict what will be the outcome of bitcoin or cryptocurrency in the future but nevertheless if bitcoins still exist during that time the price of bitcoin may really reach a more than what we expected. But if any cryptocurrency will be adopted I am positive that either the government or any financial institution will take place and would tend to manage the exchanges for bitcoins and other cryptocurrencies which probably control the rise and fall on its value. I have read an article that JP Morgan is now accepting some altcoins for savings and that made me think if cryptocurrency will be adopted today. Nevertheless, after the pandemic or any time in the future surely it will still be in control of someone who will govern the value and usage of cryptocurrency.

I even don't know what's to to be happen in the nexr hour. To 2140 is like 120 years to go. I guess I won't be alive until this time.
That's why I think we must live in the moment. bitcoin is giving us nice profits over our investments and we know until the next year the price should take another pump. So, better to use the bitcoin until we can. Nothing lasts forever, not me, not you and not bitcoin. like all other currencies. bitcoin will end one day. but until that day I know I won't be alive.

We will never know what will happen to bitcoin in 2140. There is a possibility that bitcoin will be replaced by a technology
more sophisticated, but if bitcoin turns out to still exist I agree the price will be very expensive. Besides, it's possible in 2140
I have died, so I can no longer see bitcoin in 2140. So I prefer to predict bitcoin for 5-10 years from now.

There are bunch of factors that have different weighted effects on bitcoin in the future:

• How many percent of bitcoins unmoved over consecutive years (like 10 years, 20 years)? They are mostly lost.
• The level of bitcoin adoption that discloses via its median of total transaction counts per block and median of weekly empty blocks
• The transaction fees (how high/low & stable will be?)
• The general growth of crypto industry
• etc.

[1] This figure is very important because it helps us knowing how many bitcoin potentially lost forever. It plays as an unofficial deflation for bitcoin's touchable total supply.
[2] See: BTC empty blocks (2009 - 5 May 2020): miners, size, daily, monthly,yearly stats (https://bitcointalk.org/index.php?topic=5245684.msg54380101#msg54380101). For the first part of point [2], you can get it on glassnode.com (https://studio.glassnode.com/metrics?a=BTC&m=transactions.Rate) (click on the link to see the chart)
[3] For transaction fees, there are 2 main factors: cheap/ expensive; and stability. If in the future, there will be improvements on the Bitcoin protocol to make its transaction fees cheap (most of time, it is cheap) and more stably cheap, we will see more massive adoption and real usages of bitcoin in daily life.
[4] I do believe that we will be early witnesses for one of the greatest revolution in human history and human civilization.

Bitcoin will have a really good future, if only the government is not going to do anything very stupid. If the government is not going to start looking for ways to take it down then it's going to be really good. I have been seeing a lot of people talking about Central Bank Digital Currencies (CBDC) and I'm not really in support of these, because I don't want the government to create something that will give them a reason to fight against decentralized cryptocurrencies. They might want people to only make use of centralized exchanges and not the ones that are decentralized.

OP is talking about $1M for one bitcoin in 2140 whereas McAffe kind of people are speculating the same level of value for bitcoin within this year or at lest within this decade. So much of differences. When people are having confident about reaching $1M then it will be reached quicker than expected so, $1m may possible at any time soon.

The generation has to born yet which will be witness of our expectations about Bitcoin anyways I believe Bitcoin will be still on top at that time, not sure about how much market capitalization will be but it may be beyond from our expectations the adoption and popularity of Bitcoin indicates that its future is going to be far long.

Are we really waiting for Bitcoin in 2140 at a price of $ 1 million, it did not occur to me and never dreamed that it would reach that year.

If it is currently lacking in 2020-2140, then the age we must have in 2140 is 120 years from now.
OP, how can you think about it? You can have the opportunity to mine in Bitcoin that year.
Even if you have the chance to live in 2140, I guarantee you will not be able to get to know Crypto any more, and also you will no longer be able to operate your laptop again, you are very senile.
At that time you will no longer know the name of the internet and related to the world, vanished.

Great topic OP.

I think in the year 2140 the bitcoin will be managed with satoshis, let me explain it. Miners fees with being really small, something like (0.0000001)...it will be a small amount in bitcoin, but a nice amount in dollars. And this will be because with all the lost coins the total of circulating bitcoins will be low.

Is just my theory for that year.

2140? Oh noh! ::)It's more than 100 years or 120 years to be exact from now and i think there is no people from this year are still alive on the year. But maybe Bitcoin is very valuable at that time. Miners already mined all bitcoin and only small supply of bitcoin will circulate in crypto space. Anyway,It's really difficult to imagine what will be the bitcoin after 100 years.

By the year 2140,all currencies(both fiat and crypto) will become obsolete and people will have robot slaves,that do everything for them and produce all the things people need.Markets and the economic theories of supply and demand will be forgotten.People will colonize other planets(or maybe Mars only).
Quantum computers will be a thing(there might be computers that are even more powerful than quantum computers),so Bitcoin won't exist.There's no point of fantasizing about what happens to Bitcoin in 2140.

I would imagine that by that time, we wouldn't be saying that Bitcoin is worth x Dollars, instead we'd be saying that a Dollar is worth x% of a Bitcoin. There is no way, surely, that over a hundred years from now we'll still be using fiat as the primary measurement of value. Fiat looks hopelessly antiquated now, in 2020. We are moving into an interconnected digitised world at breakneck speed. In 2140, fiat will be irrelevant, if even still exists.

If we talk about the future there will be many possibilities. Bitcoin become scarce and it will make its price increase, I can't predict how its price later but if we see the increase price per halving event the price should increase for more than 1 million per 1 BTC. But if we talk the other possibilities like the demand for bitcoin is less and the miners will leaving it because its cost that expansive I guess bitcoin will just a history. The people will sell all their bitcoin until its price goes to zero. As for the miners side, I'll answer it will be depend on bitcoin's price itself, the miner will still mining bitcoin if they feel they still make a profit of it and otherwise.

I don't think too much about what will happen with bitcoin after the year 2140 because I don't know what will happen with bitcoin. We will have so many predictions about what will happen in that year, but we still don't know for sure because all of us will not live until that year. Maybe we can give a message to our children, grandchildren to watch what will happen with bitcoin, so they can prepare before that time comes. But I could only predict that bitcoin at that time will be too expensive than today, and people will want to hold bitcoin because bitcoin is worth for them. But who knows the truth?

I think you should be able to see from the basis of bitcoin and the purpose of bitcoin from what I know is that bitcoin is created to create an exchange value that cannot be controlled by anyone and has a very limited supply limit and is widely used for various platforms to make transactions digital, while life in the digital world will always evolve so in my opinion the year you mentioned that the price of bitcoin will be very expensive because it is very difficult to get bitcoin and more and more are using bitcoin.

That's a wish that is too far away, I don't think is very important because before that "possibility" is reached in 100 years, I think we will disappear first from the earth. We know that it is very rare now for humans to be more than 100 years old. So it's best, we try our best to benefit from the offers available on bitcoin at this time, don't daydream too far. By studying as well as possible to get a profit that is enough for me to be able to enjoy this progress. I think, in the next few decades the adoption of BTC will increase, of course, it will increase its value.

To be honest, even I'm not sure I will live in that year so I would never be able to imagine the growth of bitcoin in 2140, even though bitcoin is able to continue to grow and become something that is very useful and sought for many transactions in real life I'm still not sure bitcoin will persisted in 2140 because every technology will continue to evolve every time which led to a major transition that may occur to an era that is more intense than the digital era as it is today.

It looks certain that Bitcoin will be more expensive in the future, because of its deflationary model. For instance, fees per transaction have been on the rise after the third halving. This way, miners are able to "compensate" their losses with a reduced block reward. While it's good for them, it certainly isn't good for everyday users like you and me. If this keeps up, I believe that Bitcoin will be more used as a store of value than just a digital currency for daily payments. Of course, there's the Lightning Network but adoption is very low these days. Even with the benefits of the LN, Bitcoin would need to increase its block size capacity to be able to process more TPS. The LN is limited to Bitcoin's block size too, as opens or closes channels on-chain.

Still though, a lot of things could happen by 2140. You and I won't be able to live up to that point, but future generations will. If development is on-going, I'd bet that Bitcoin would've been scalable and stronger by then. I don't think it'll die easily as it has become too popular in the mainstream world. The pioneer cryptocurrency could simply become Gold's successor, as people use it as a safe-haven asset in times of turmoil. As long as decentralization is put first above all else, Bitcoin will be able to last far beyond 2140. Just my thoughts ;D

Year 2140 - I don't know if any of us here will still be alive at that time. But I am thinking that maybe, another powerful cryptocurrency will be born and bitcoin will be obsolete at that time. We know that bitcoin has a lot of shortcomings when it comes to speed and transaction fees, so something will be born that people can't resist. Although there are so many alts that were created to replace bitcoin but up until now, no one can beat the popularity of bitcoin. So after 2140, there will be so much things  that will happen and technology will be advanced that cryptocurrencies might not be in at that time.

It's always interesting to talk about the future of bitcoin, because many people believe that in the future bitcoin can become a global currency.
In my opinion bitcoin in 2140 which is all bitcoin are mined, which definitely makes the price of bitcoin more expensive and also the price
more stable. And what is interesting is that all major merchants will accept payments with bitcoin. If that is indeed the case, I can't wait for it.

Just like Bitcoin was launched by satoshi in 2008-09 as new financial system, somebody in future may come up with another idea and we all start following that and abandon bitcoin along with other crypto. That's just one possibility for 2140, we all wont be here 2140 but lets post with hope that this forum will be there in 2140.

Sorry but i don't think Bitcoin and cryptocurrencies will just gone like that and people will abandoned because new one comes out?there
 might be another one but nothing can make difference from Bitcoin as this is a currency back by technology
and not just some amount to be spent.

just like banks,why they are staying even there are so many online sort of transactions?there  are paypal,paymaya,Bitcoin and other
 form for payment yet Banks still lives and making money from the users.

if i am to support your position?maybe not to abandoned Bitcoin though i
 doubt that i am still alive and active that year.

that was 120 years from now so if you will still be alive by that time you cant still use your gadgets and prolly be lying on the bed only due to weakness caused by aging or some health issues but lets not talk about the future shall we . what more important is today   . btc , crypto and blockchain are lively  and will be more lively in the next few weeks and months . after the creation of btc , few years later many simillar inventions showed up but look at btc now . still the one that is in favored the most

If Bitcoin solves the issues with scalability, and miners can indeed live off transaction fees, I don't see why there would be strong demand for altcoins. They are slowly dying already, and maybe some will survive, but I don't think a big number of altcoins will be in use. By 2140 a lot of stuff can happen. Humanity might finally kill itself and the survivors won't have time to deal with cryptos; quantum computing might see a breakthrough with Bitcoin and most cryptos rapidly failing (but new quantum-resistant ones probably taking their place). I think the fact that all BTC has been mined will be the least of concerns in any case because even if everything remains more or less fine with the world, prior to 2140 there'll be a long period of time with very small amounts of BTC mined and most miners probably already living off the transaction fees. So the way I imagine it, it won't be a rapid change.

We didn't know how long it last but it's good to see if this one rolling since provably we can see more of it when bitcoin still adopted on year 2140, The one I see for that year is a good adoption with government ruling about the blockchain system. There are so many speculation regarding on this matter but I will not drop my speculation since this is just pure fantasy maybe lets wait for years pass on what will happen by that time since if Bitcoin will live strong we might gonna see a good adoption in the future.

After 2140? Not much different as 2100 or 2080 or 2050

Most interesting rather 2024 (after next halvening) / 2028

?

Bitcoin economics and global compliance will decide that

We cannot even predict what bitcoin is going to do tomorrow so it is difficult to imagine that we will be able to predict what it is going to do or happen in more than 100 years in the future, however I think it is fair to think that miners will have to depend on the fees they get for their services and not from the block reward way sooner than that, is difficult to know when that will take place but I suppose that process will have to begin to take form during the next decade as the halving keeps reducing the reward for each block.

The future of bitcoin cant be predicted by anyone and what we can say is some speculation about it. The level of difficulty faced by miners who will continue to grow every bitcoin reaches 210,000 blocks is a sure thing. However, miners will still exist even if they have to depend on costs.
I imagine bitcoin will continue to get good adoption from various countries and many countries will adopt it as a payment system as mentioned in the bitcoin innovation.

As an asset that has a function as a currency, bitcoin can be superior to fiat in terms of transactions and simplicity. The community will continue to make it a multi-use currency that can be transacted for various purposes, especially we already have a flash network.

Maybe we'll end up with a very small number of altcoins (mostly Ethereum, Litecoin, and other coins in the top 5 ranks in market cap) on the market by 2140. Bitcoin will still be relevant as a digital store of value anyone can use in times of need. My guess is that Bitcoin will be scalable enough for the whole mainstream world to use. Miners can still live off transaction fees, even when all coins are mined by 2140. With sidechains and many other useful features coming along the way, I believe that Bitcoin will become an "All-in-one" cryptocurrency in the future.

Of course, technology constantly evolves over time. If a new contender comes out with better tech than Blockchain, then Bitcoin won't be able to live that far. All of this is pure speculation than anything else. At least, we won't have to worry about Bitcoin's future in our lifetimes. We can continue to enjoy Bitcoin as is, leaving it as heritage to future generations. If Bitcoin continues to prioritize decentralization above anything else, it'll be able to live for a very long time. With the rapid development of the Blockchain industry, it's expected that Bitcoin solves scalability & privacy issues by 2140. Let's just focus on Bitcoin's development for the next 10 - 15 years. Just my opinion :)

As you said that the price of bitcoin would be enough to support mining operations as the fees would makeup for the coins they were mining before, I won't agree with this as anyone can understand that right now the block consists of a reward of 6.25 BTC which is equivalent of 60k USD in newly minted coins and the fees is kept by the pool for the purposes of operations and management of the pool. So i guess the block size should be increased to make the reward same as of right now as more transactions would be filled in a single block which would mean more reward for the miners.

This is a super long-term projection and I'm not o sure that in a century's time there will be something like BTC or cryptocurrency but instead some other higher form of financial system. I expect the technology to lead us towards a feature we can't yet possible imagine and with Ai and automation already sprouting biotech and info tech will take over and so it makes any long-term predictions like these almost impossible to even guess. That's my take on it anyway...

Do we really need to think that far? I mean it is clear that we are already gone and mostly our child we also be gone by that time so I think there's no point of thinking about it too much.
But I am also curious about how things would be in the future would we leave something that our future generation could look into would this forum be still alive at that time?
Just thinking about it makes me laugh just imagine if this forum is still alive then how many generations have hold onto theymos account and also those trusted campaign managers account.

$1 million per bitcoin, that's a good price, but that long, I think we will no longer enjoy that.
Bitcoin if it will remain at the king of all coins in crypto, it will affect altcoins, but with the big number of altcoins being created, 120 years from now, for sure the competition would be very big, probably a million of altcoins the least.

I am afraid that talking about the value of bitcoin in 2040 is now too early when we are only in 2020 - that is, 20 years later. However, I support your opinion that Bitcoin will be very valuable in 2040 - when blockreward = 0, minner will not receive block reward anymore, minner will only receive cost when they make confirmation. money transfers. If the value of Bitcoin is not attractive enough for miners, the bitcoin system will collapse because no one will confirm the transaction. The future of cryptocurrencies is still very long, let's save this article and open it to check in 2040 to see if our speculations are right or wrong.

in 2140, it is 120 years from now and in that time span, I think that there are more things that will occur or happen, maybe we don't expect a new emerging cryptocurrency that can beat bitcoin when it comes to its price. In reality, it is hard to predict the fate of bitcoin especially there are a lot of factors that can affect its price. Sometimes you need to have basis about your predictions, so that it can somehow get into the fact and reality.

Bitcoin can really grow after so many years because of its volatility in the market, we just need to understand that nothing's permanent when it comes to its price. We all know that bitcoin is just for a short-term investment compared to gold that you can invest for a long time.

Also there are potential altcoins that can surpass the price of bitcoin, we never know. There are a lot of possibilities that there are more coins that are not yet existing and can surpass the price of bitcoin as a digital currency.

Let us share this to our children because they are the one who will cherish those moments,because 20 years is too long for us to wait.

and how lucky they are having a Million dollar Bitcoin value while in our time we cannot even touch 100k?

after the mining ends when the 21 million Bitcoin already taken out?there is the time that the true value will be decided.

I don't know whether I'll be there in 2040 or long gone but one thing is clear Bitcoin will be at the position of dominance.We are thinking of 20 years from now and in 20 years whole world can turn up side down and anything can happen.But I think in next few years itself Bitcoin will be double it's price.And if we think about miners than unill Bitcoin is there nothing can happen to the miners.

By the time like that maybe we are all dead at that time and the only one who can saw and experience that is the next generations next to us. Let us all hope that bitcoin is still the one and still the king of all cryptocurrency not only because he is the very first cryptocurrency in the world but also he is still be on the top and marketcap and market price in the future. We are very very proud of being the first to adopt cryptocurrency this time.

Probably you're right, as of now, bitcoin is still really far from those altcoin and it is still the most popular and effective cryptocurrency that you can manipulate as your asset. I'm pretty sure that in 2140, I'm already dead and I need my kids to understand and keep my bitcoin under their control so that they will benefit what I've invested for a long time ago. Bitcoin is somehow stable for the mean time and I see some upward spike about its price in the market. It is really to predict bitcoin right now because of its volatility that is actively changing in its price. We all know that bitcoin is a limited and if we mined all of them in 2140, its price will become larger than today, the demand will increase but the supply will not grow.

$1m USD per Bitcoin might become a reality by 2140. But even you and I won't be able to witness that. At least, future generations will be able to enjoy an extremely valuable currency that's completely decentralized. By then, I'd expect Bitcoin to solve many of its issues like scalability, and privacy. Probably, Bitcoin will be relying on Layer-2 solutions and sidechains in order to achieve this. The main Bitcoin blockchain might remain with a 1 MB block size if the LN is able to reduce high transaction load. Many miners will be living off BTC fees, as the block reward will reach 0.

As far as altcoins go, I believe that only a select few will be able to survive on the market. Mainly Ethereum, Litecoin, Monero, and Dogecoin, will continue to be actively supported by people in the mainstream world by 2140. If development continues, I'd expect new features across all chains. No one knows what exactly will happen by then. But one thing for sure, is that technology will be a lot more advanced than what it is right now. The industry will constantly evolve until it becomes a "force to be reckoned with". If a new Bitcoin contender emerges by 2140 with better tech than Blockchain, you could expect Bitcoin to reach its "end of life". After all, nothing lasts forever. At least, we won't have to worry about this in our lifetimes. Just my thoughts ;D
