Bitcoin Forum

Everybody says Bitcoin is unbreakable, set in stone, yadda yadda yadda. But it seems to me that this is not necessarily the case. Anything about bitcoin, including the amounts generated, method of transferring coins, size of blocks, time to mine blocks, etc. can be changed by changing the software, and in particular the reference client since so many miners use that. Really, if 51% of the bitcoin mining community agrees on a change and implements it, that blockchain will win out over time. So it's more of a democratizing of fiat rather than an unbreakable currency.

There have certainly been times in our history, even in the recent past, in which the country at large (US) has voted for a Keynesian monetary policy. Isn't it possible, even likely, that at some time in the future a majority of miners would simply implement software changes to increase the amount of bitcoins generated? The incentive to do so is rather large, is it not? Thoughts?

Yes, it is ...

Nothing is permanent. It is very possible that something pops up down the road that will overtake Bitcoin. As of now there is no competition, but a superior cryptocurrency could gain massive popularity at some point down the road and make BTC obsolete.

This is a good question, but not only miners would have to accept the change but all full nodes too. In other words you would have to convince everybody using bitcoin (miners and fully validating nodes) to change. That's not an easy task. People that understand Bitcoin's 21 million limit understand it makes coins more valuable than keeping inflationary printing. People would be voting to decrease their own net worth.

There was another coin that tried higher inflation rate. I can't remember the name, but basically the longer you held it the more value it lost, which was to encourage people to spend/use the coins. The theory was the higher transaction activity would create more economic value and the coins would be worth more. I don't think that coin is still around.

Bitcoin essentially is a consensus, a protocol that people voluntarily follow. You can't really break a consensus since there is nothing to break, it is supported by every participants, not enforced by an authority or military force

In a centralized system, you could change the policy as you want if you are the commander. But in a decentralized system, the participants are connected by a similar interest and consensus, many people join bitcoin community because they prefer limited money supply. If some participants do not like this monetary policy, they can leave and mine their alt-coin with whatever policy they like

If some large mining farm fork the coin and increase the coin amount, they will generate a fork of bitcoin with unlimited money supply, they can even maintain that chain to have enough strong hashing power. However, they can't force people to use their chain, and their chain will be called something else and become useless for bitcoiners, and bitcoiners will still use the original chain

People might never understand what central bank is doing, but bitcoin is open source, even a line of code is changed, it will be examined by many developers. On internet, people won't be fooled like in fiat money system

Hmm those are some good points. Technically, the Fed runs on "consensus" too by means of who people vote for, but they vote on other issues too and then there are levels of appointments from Yellen on down. The main advantage I suppose is the transparency, so that were a large percentage of miners to attempt to increase their mining (which would decrease the overall value of bitcoin but increase *their* percentage of it, much like the gov't printing money), it would instantly be public news and the bitcoin market would factor it in quickly. Nodes that don't generate blocks might not accept the changes, but what if all the miners did? Then there would be no other alternative blockchain for the full nodes to use.

I don't think the profitable miners would drop their mining operatons easilly. As long as the bitcoin has value in terms of fiat money, the miners will keep mining to secure the network. So the blockchain will non stop. The node will get working, and the transactions get moving. The way of the bitcoin running is completely different from the fiat money! Miners and nodes are incentivized to keep its system running.

well, the beauty of bitcoin is that it is opensource. we don't need to worry about another digital currency taking over bitcoin's place. bitcoin can get much better for global usage slowly once the need is there.

Not really! Crypto market is in strong competition (http://coinmarketcap.com/). The dev should be active and the coins' features should be upgraded frequently, otherwise the coins will lag back. Although bitcoin has a lot advantages comparing with others, but if it encounters some issues or there is no updated functioanality, it will be replaced by others.

What's the incentive? Why is it likely?  I can only guess at why you would come to such conclusions.  I think the opposite.  I think there is great incentive against changing such a core part of the system and it would be very unlikely to change.

Maybe you conclude that miners want to just 'pay themselves' extra, but if you think about it, many people would disagree and so there would be a fork.  And the diluted coin would be instantly deemed inferior due to its reduced scarcity.  In turn, no miner in their right mind would waste their hashing power on it.  

Don't forget, users have nearly as much power as miners have.  They're the ones that are BUYING all those mined coins!  If the users don't buy DiluteCoin, (and merchants don't accept it), then miners are hashing a useless coin. 

IF it is everlasting, the Nakamoto-san will be known to us all.. :D
Frankly, i think bitcoin will become the bootstrap for the next coin, the problem with "double spending" is not yet fully covered, it is still the biggest loop in decentralized world, it still depends on the theory of "if it is too big to solve" kind of approach

Bitcoin has a huge edge over all other cryptocurrencies due to its popularity, but if 20 or 30 years down the road the entire world is using digital currencies, it is very possible that something more optimal is released that takes Bitcoin's spot as the crypto king.

Not everybody.

if 51% agree(actually i read that you need 90% for that, i don't know if it is wrong or what) then it mean that the majority want bitcoin to be changed and so it will be, the point is that there isn't a single entity that can change everything as he wants, that's the beauty of bitcoin

Yes. But 51% of whom?
Think about it. Do you have a voice?

no probably, but at least you can vote, with fiat you cannot do anything really

maybe the problem with consensus is that only miners and merchants but mostly miners, have the real consensus, instead i believe that those that are running a full node should have the same power, and should be rewarded too

so the bitcoin consensus is good enough, but they way it works right now, could have been better

what if, for some kind of calamity, most of the bitcoin private key owners die and so the value they hold is gone forever?
In this scenario only people would die but network would be still up.
There would be very small quantities bitcoin available around the world.

In that case bitcoin would litteraly disappear within few hours.

Who will reward them and for what?  ;D
Are you crazy?
There is no free beer! Every bottle is paid by somebody else!

well it could be done that instead of sending all the fees, from any transactions, to the miners only, you send a portion to who is running a full node

maybe something like 1k satoshi, 10% of the default fee

It's 51% for usual fork, and 90% for xt fork, since it has that limit for activation in code.
Bitcoin is safe, but it's not immune to attacks, but then again, neither are other alternatives. Considering how much one would need to "attack" the network, it's safe to say that it's futile.

The biggest problem is the client-side security, where most people get infected by mallware of all sorts, and don't know how to protect their coins from theft.

cheers

OK, 1000 satoshi per tx
There are 100k daily transactions
And 6k fullnodes
The daily revenue for each node is 16667 satoshi = $0.04 - great results  ;D ;D ;D ;D

well you are not taking into account the potential of bitcoin, and the much greater number of TX per sec and the price, for the future,. that 0.04 could be 40

also it was only an example, you can tweak it to suit it better, but bears in mind that it isn't something that aim at replace your job....

IMO, that's hard to do. If you're going to allow nodes to get fees, you have to split the fees around 5000+ nodes and the miners would receive less incentive to mine. Running a node is significantly less expensive than mining. They can easily just host nodes and stop mining. The security of the network would be reduced significantly. Many people also would like to send transactions with no fees.

That's considering that people are using default transaction fee per size, but it should be much more if the number of transactions continues to grow with time i think.
imho the reward process should both include reward to nodes and PR efforts through some organ, but then it would make it more centralized, which most people don't want,
although it would make bitcoin itself much more spread out and therefore more secure.

cheers

The miners are securing the network and getting the transactions inclued in the blocks. They should be paid. But for nodes, we needs nodes as well to broadcast the transactions out. As bitcoin's adoption rate increases, more and more nodes will arise. This is not a concern for me!

Full nodes are important too. They help to enforce the network rules and allow other nodes to download blocks from them. The rise of adoption rate doesn't guarantee that people are going to open port 8333 to allow outgoing connections. The block size issue would probably make people use SPV client instead which does nothing to contribute to network and it relys on miner to follow network rules. A problem we seen from the recent fork.

I think what OP is trying to say is... If changes could be made to increase the 21 000 000 Bitcoins and a majority of the nodes accept that, like the Chinese miner pools just did, for a while... could that break Bitcoin?

Well, I guess it's not impossible... but the incentive to add more coins would negate the advantage of doing it. More coins being released, would push the price down. {The more coins that are available, will push the supply up, and IF the demand is not enough, the price will decrease}

So there is no incentive to do that.... The miners benefit from the scarcity of the coin too. 

well as i said above you can tweak it to have an appropriate reward, if 10% is still too high you can reduce it a bit, for example i doubt that mining activity is worth more than x20 in comparison to running a full node

the point is that running a full node should be incentivated, they could help against sybil attack and reinforce the network, therefore they need something as a reward

I'm not sure why there is so much confusion about consensus.

~90% is more accurate than 51%.  51% is just the amount of hashing power needed to consistently mine the longest chain, which is consensus WITHIN the protocol.  But you need everyone on board for consensus of the protocol itself.

If "the majority want Bitcoin changed", well you have to consider that 1) this means the majority of EVERYONE using Bitcoin, including users, investors, and merchants, not just miners and 2) unless there is an overwhelming supermajority, the substantial minority left behind will continue running Bitcoin in its previous state.

At least two group of people won't change their stance: Austrian economic school supporters and libertarian

In fact many miners are still learning theories about money creation (What they do is money creation), and I think many of them will realize that limited supply is the only way for a consensus based, voluntarily participated currency to succeed. Without this property, bitcoin does not stand any chance before the competition of fiat money (If both currency are inflative, then most of the people would rather use FED's notes instead of a group of greedy miners' coin, at least FED's coin is backed by the US national debt :D)

It wouldn't completely negate the advantage. That is why the gov't prints money. Say that the miners (collectively) decide to double the number of bitcoins to 42 000 000. And just for the sake of example, let's suppose the value of a bitcoin starts out at $1 (the value itself is irrelevant). After doubling the number of bitcoins, a bitcoin is now worth only $.50, but the miners have $10,500,000 that they didn't have before. Actually, at the real price of $250 per bitcoin, that's $2.5 billion for the miners. That's why I say the incentive is rather large.

Miners are the new bankers.

Heh. I think that that fiat being backed by the national debt is an argument FOR bitcoin. Plus the ease of use.

you miss the point even if BTC was broken, then another crptocoin would swiftly take its place, and BTC core would likely update to that tech. Eg POS if miners failed.

So yes BTC coin as a crypto, the idea is unbreakable. Go and take a look in alts if you doubt this.

I think since the bitcoin was one of the first digital currency(crypto currency) it's not much breakable.
Since it is so popular it takes time to break it.
There are more other coins(inc. crypto 2.0) that are much faster but not so pupular like bitcoin

Are you sure?  ;D

Are you sure?  ;D

That is for sure. If there is no bitcoin there will be something else replacing it immediately. Arent there many many other coins?

Fiat, gold, jewelry etc.
And all of them have the same flaw: they can not be used as financial tool.

what is the reason for that? why they cannot be used as a financial tool,, they are currency to all effects
plus they can be used as a great investments, they have the right to be used in the same way as fiat
but with a store of value and better fee and security

No. There is one significant problem: cryptos like bitcoin takes too much energy to prevent doublespends comparing with any other ways.
great? are you crazy?  ;D

I believe that Bitcoin is one of the first to implement cryptography to prevent double spending in p2p technology. Other ways would just make it more decentralized. The Bitcoin network hashrate and energy consumption rate can be huge but ASICs are getting much more efficient and slow miners are gradually shutting them down. Basically, to get cheap power, most of the mining farms are located at places which have renewable energy. POS might be a solution but 51% attack would be made much easier with much less expenses. I would say that Bitcoin miner consume less electricity than all the datacentres.

Yes. But what is the cost for it?

By analyzing all comments, it gives me understanding that Bitcoin will be mere age till it finishes it's 21 millions productions, once it overs or in the middle, any other new innovations will raise up by individual or Government itself, if Government brings such attractive crypto solutions then everything will become centralized, that won't be an appropriate for us.

the cost is high but the price of bitcoin is high too, the ratio will be maintained at 1:1, thing about it when it was the beginning, the cost of the network was very low, but so it was the price

the price for maintaining the nwtwork it doesn not matter if it's reflected by a good cost in the market

not to mention that the heat can be actually useful in the winter

i remind you this quote from satoshi

"The utility of the exchanges made possible by Bitcoin will far exceed the cost of electricity used. Therefore, not having Bitcoin would be the net waste."

The fact p2p is spending is one of the reasons it's so valuable, all costs to achieve this goals are nothing compared to what you get with a decentralized wordwide p2p currency that solved the byzantine generals problem.

What if the cost of solving byzantine generals problem is more than a cost of army?  ;D

I would imagine that the cost of mining and running the blockchain is far less than the cost of the current banking system and financial industry.

per one transaction?  ;D ;D much more!

Yes, it really is unbreakable, with various caveats.

At the point of bitcoin exchange, there is vulnerability with bogus wallets and nefarious schemers...see Mt Gox fiasco.

Otherwise the system is sound, secure, decentralized, and pseudo-anonymous.

the army does not work at all unless you solve the byzantine generals problem. Eg everyone just hyperinflates when taken to fiat currency issuance.

Well, it's certainly forkable. And this leads to problems with it being accepted more widely. The recent fork wasn't that bad (a 5 hour confirmation time is still great compared to credit cards), but you could imagine a situation where 51% adopt new specs but a 49% blockchain goes on for a long time, wreaking havoc among merchants and customers.

well the nextwork can handle 150 TX sec, with some downside... based on the last stress test, we are still far away form visa and company but the difference in power should be the same at the end


the miners are both the strengths and weaknesses of bitcoin

but you can always restart from zero if soemthing bad happened, cryptocoin will never die no matter what

Impossible because of decentralization.

you think that because of it, the miners will grow indefinitely and thus rising the power to a much greater extent? well a central autorithy could see this as a competition, and use more energy to increase its network/circuit in the case of a centrlized system like visa/matercard

or maybe you are referring to the contrary

Well then we need to invent decentralized electricity aswell. Until the electricity is controlled by paid shills, they can easily increase the electricity bill cost just to mess with bitcoin mining.

Very true. For the moment the technology behind Bitcoin and it's dominance in the cryptocurrency market seem unbeatable, but the future is difficult to predict. Anything could happen.

No its not.It can still be broke nothing in the world has the best security even the strongest may fall.But thist past years bitcoin stay strong and at it's finest of all cryptocurrency and it keeps on growing.But i still hoping that someday bitcoin will be unbrekable and unstopable online.

There will always be problems like 51% attack, but it is one of the safest systems until the dates

Yes i agree because bitcoin is can be manipulated by all of us if we want it to dump we can dump it if were holding big amounts of btc and thats why its breakable for now and their so many scene and instance can break bitcoin if something black propaganda wil spread it can be the cause of bitcoins falldown.

Not really. Let's think this through. Let's say 90% of miners decide to implement Bitcoin B, which increases the block reward tenfold. The other 10% of miners stick with bitcoin as it exists today (we'll call it Bitcoin A). The result is a hardfork and two competing blockchains. Exchanges and the general public are forced to decide which coin they want to go with. Some exchanges stick with Bitcoin A, some with Bitcoin B, some offer to handle both.

Because the miners on Bitcoin B have demonstrated they will jack with the coin supply, confidence is near zero that they won't do so again. That and the flood of new Bitcoin B's into the market from the miners quickly drives the price down towards zero. Meanwhile, the miners on Bitcoin A see the value of their coin sustained, and they are earning 10X as many bitcoins because of the lack of competition. Rather quickly the humiliated and financially stressed miners of Bitcoin B start abandoning their ill-conceived effort to alter the supply of bitcoins. Within a few weeks, Bitcoin B ceases to exist.

The public could support a restriction on the block reward, reducing the coin supply, in principle. But so long as anyone was willing to mine the existing protocol and exchanges were willing to support it, I can't see the opposite happening. Except maybe if world governments stuck a gun to the head of miners, exchanges and the public and said "You will accept only Bitcoin B - or else."

presently its look like so. in future what will happen nobody know about that. but if we look at the present situation of the bitcoin its look prety good. it is look like unbreakable. is is expected that  the rate of bitcoin will increase in next few months. so we can expect that it will remain unbreakable in future specially in near future.

I agree with this aspect. Today Bitcoin, you can say, well received by the public. State banks and injected it into circulation, use. that only strengthens Bitcoin. Bitcoin increasingly gaining confidence, and thus becomes stronger.
However, I remembered that 60-70% Mining farms accounted for China. And if there is something wrong in China, and other countries will not be able to pick up the power ... scary to think what will happen.

The bitcoin protocol, like any other, is theoretically only unbreakable until it actually gets broken.
That said, it has been opensource and received numerous attacks over the last 7 years, that it seems reasonable to regard its overall security as fairly robust.

There is always a change that it can break but that will not happen soon because you already can see also that the value is going to be more worth and it is becoming more popular.
So that is really nice but you are not for sure what will happen later with the Bitcoin and what you have to do with it.

Everything's break in some point for now bitcoin is much more stable by this time. Its just like a glass if you cut it in half many times it will break. Same as bitcoin and from that moment some altcoins will replace bitcoin by then. So i think be vigilant on it what altcoin it will be. For now let's just enjoy bitcoin.  ;D

no one can say anything about the future. but this time its look like that bitcoin will keep itself stable. lets see whats happend in near future.

As you have said it bitcoin is not unbreakable. It is not a solid currency. It is not even legalized and there are no governing rules from the government in using bitcoins. Bitcoins are prone to hacking if the user is not careful and its price is unstable, though it is high today we do not know what will happen tomorrow.

Well really, really everything is of course breakable but considering it for the bitcoin its just highly unlikely.
The bitcoin is just so strong and cannot be defeated in my eyes.

I don't believe that bitcoin is unbreakable. Besides the technical side, there are no guarantees that bitcoin will fully catch on in the mainstream. It could just be a minor financial tool or just fail altogether. There are just no guarantees.

Yup Bitcoin price gonna be stable after halving, I won't accept which you said that, Altcoin will replace bitcoin then. Because I believe nothing we can compare with bitcoin while we looking at the current price hike.Really We should accepts this decentralized money is unbreakable at any moment...

Those member who gave their different opinions  here are really a big help to each everyone of us,..due to everybody or majority here they loved Bitcoins.  True it is totally now really unbreakable as time goes by of how the other business company adopt it and the mass adoption are actually so fast in the other countries. :)

yes i hope so. the reason is that the popularity of the bitoicn is increasing day by day and there is not doubt this. people are entering in the world of bitcoin. they have trusted on bitoicn.

So newly minted coins in each block has dropped from 25 BTC to 12.5 BTC.
Now we mine daily 1800 BTC in new coins and 100 BTC in tx fees. So tx fees went from being 0.00125% of the income a year back to the 3% of mining income they are today.
 ( Sorry if my calculations are flawed)
But you can see, mining does not stop when the minting of new coins stops.

I would say that the way bitcoin break down is that there is in a couple of years a better alternative and that people simply changing currency...

Bitcoin is a long way to go to replace fiat currency. The world is not ready for bitcoin as a legal tender. We even do not know if satoshi nakamoto made bitcoins to replace paper money. There are no exact words coming from him  that describes it. If there are it is not from him but from the financial analyst who observed bitcoin and made a theory that it can replace paper dollars.

bitcoin can never be unbreakable or completely worthless even it is overtaken by other technologies, as it will always retain some value.

Its a bit to much, and I doubt its unbreakable. Maybe I`m to hard with my opinion, but everything have beginning and the end. Its the nature of things, and we can not run away from that.
Yes its digital era, and technology is present everywhere, its a future. Bitcoin can be set in stone, but also something bad can happen, cause we all know that bad things happen all the time.
I will not think about this things, I will enjoy the moment and in everything that bitcoin provide me in this moment.

yes its true bitcoin get increasing popularity day to day and i think bitcoin will get more popularity in the future and i hope that bitcoin will be most famous currency of the world and it is the main reason of bitcoin is unbreakable currency .

This is a broad cryptocurrency nowadays and yet the top 1 cryptocurrency online. So I guess as of now, it is still unbreakable. And also, because of the members who are still using BTC, then this will be a big deal to the society. Maybe years from now, BTC value will be reduced. And so, this will be the breakdown of the BTC. There is no permanent in this world except CHANGE. BTC value may be vary. Who knows ? But as I mentioned earlier, BTC is still unbreakable but who knows when do it end ? Who knows where do it end ? They say 21 Million BTC is the maximum capacity. And yet we are on 75% on it. So there is a chance that BTC will break soon. Who knows when..

For now yes it is unbreakable , but we don't really know what will happen in the future of bitcoin, maybe in other next year bitcoin still unbreakable or vice versa would happen ,but I still believe in bitcoin what ever is happen.

I think btc is unbreakable throughout its nature. Just like PGP keys

All of the cryptography used in Bitcoin today will be broken in our lifetime (30-40 years). The hashing algorithms by nature are much more resistant to quantum computing but ECC is very easy (math based security) to crack. They should have plans for "post quantum computing". Proof-of-Work will be completely deprecated due to the security risks involved as a result, so Bitcoin has at most 30 to 40 years of PoW mining left before it must switch to a quantum resistant architecture. In theory a quantum computer could process all 4,294,967,295 (32-bit max) possible nonce's in a single pass (about one second).

NSA is already moving away from ECC: https://www.schneier.com/blog/archives/2015/08/nsa_plans_for_a.html

you are that bitcoin is unbreakable , and i hope so that bitcoin get more stronger than currencies and maximum people invest their in bitcoin then bitcoin get more powerful and more people know about bitcoin and about its benefit .

I think that it's very hard to hack bitcoin wallet but anyway very often people losing theri bitcoins by scams of criminals or when they are not attentive, etc.

Hacking is rather easy with trojans and wallet rippers.
That's why you should protect your wallet with a very difficult passphrase and make sure not to store this passphrase on the same pc. Else you make it very easy for hackers to get your money.

Bitcoin already proved its strength and potential as this is one of highest market exchange value in fiat currency. its just because of Blockchain. Bitcoin is decentralized open source digital currency. No one controls it.

As bitcoin is peer to peer currency, n number of people can become a part of network. And bitcoin itself has a protocol. These are some important reasons for bitcoin unbreakability.

yeah i agree with bitcoin is really unbreakable and i am also sure that bitcoin will be more stronger currency in the future and i am sure bitcoin holders will be get a good profit from bitcoin in the near future.

It's not, no coin is, but it is really strong.

bitcoin is unbreakable and the titanic was unsinkable. there is never a 100% protection, but there is usually a good enough protection which most people will accept as they believe it is safe enough. nuclear power plants is such an example. with bitcoin there is an amount you have to pay to manipulate/destroy it, which is even not certain that it would succeed. some hundred millions if i remember correctly, but i am far from sure on this one. 

The coin itself may be unbreakable, but what if a new and better coin came out and Bitcoin was abandoned?

I'd consider it 'broken' then, even if its standard protocols still worked perfectly fine. Nobody can predict the future, but my best guess is that there'll be many more BIPs in the future that help lengthen the lifespan of Bitcoin.

My friend, well, the problem is very embarrassing, such as in China, the trend of bitcoin and security may often be controlled by the government, at least I think so, the details of the reference price in 2013, the price surge. Yes, bitcoin is a symbol of freedom, but the thorough to the center of the often does not have any government like. I think, this may affect the development of bitcoin.
I think in the case of ninety-nine percent, bitcoin does not appear big problem, it may be split this situation will occur, but it is often affected by the shinaxie！！！！！！！

I doubt it could be broken or banned etc... Bitcoin is a good system and the fact it survived even with this media attention and thousands of hackers trying to find exploits in it shows it's a working system. I don't see people leaving it and it losing exchange value as well.

it is very possible for bitcoin to "disappear". Nothing is impossible, and i wouldn't count that your earnings of bitcoin are invincible, how ever, there is the chance that it one day rises to power as a mainstream currency.

Not really unbreakable but it is resilient to what other markets have encountered and failed to do.
Belief in bitcoin from it's user base is it's strongest commodity I would say at this point.  :)

Bitcoin will be never currency and your right bitcoin will not disappear but we dont know what will happen in bitcoin since bitcoin is starting to grow and grow more.. and many stores right now are accepting bitcoin.. also here in my country we have ATM machine for bitcoin but they are just 2 atm..
So bitcoin will still live long.

The center of it does not have government?
That's exactly what bitcoin is supposed to be since it should be decentralized.
You should first study what bitcoin is so you can know what bitcoin is, and it's security features.
Simply speaking, bitcoin as of right now isn't breachable since every confirmed transaction is recorded in and can be seen publicly.

Nothing is unbreakable, sow isn't the Bitcoin. There are always security issues that can't be avoided.

Security issues? If this was the case, then it would have already been used by hackers. Bitcoin as it is, is solid to its core. At this point the security issues are coming from people not being careful with installing clients. It sounds dumb, but some people just download and install anything. In short; People are wrong, Bitcoin not.

The security issues will really happen if the core wont think into some solution to keep the hash and miners making the protection around bitcoin, at the moment the hash protects bitcoin, but its because miners are active at 2100 something will change, when the last bitcoin should be mined. Sure some people dont read or take care about where the client camed and install it. Till the moment bitcoin hasnt nothing to anyone find or search or take advantage, bitcoin looks unbreakable.

I dont think it would going to happen because people will not dump their bitcois easily and all other cryptos to date are so bitcoin dependent that if bitcoin die,they will also die

I think bitcoin is now really unbreakable, it has got a firmed base in global market and each day one after another company adopt it for their business especially online business which are adopting bitcoin much faster, and in return giving a more strength to bitcoin and its community.

That is true about bitcoin it is now a strong cypto currency and it is going to build better business transactions in the future. And if more investors are going to trust it then for sure they are going to rely on it. Not just investors but big companies like gaming platform companies then that is going to have big impact with bitcoin.

You just implementing the energy of bitcoin in this time but I never believe there are an anything is real, can't getting unbreakable at this time because all of that is always having a weakness in themselves. bitcoin can be breakable?it's possible.

You have a point but for now its impossible that bitcoin can be breakable maybe in the future if they seen the weakness of bitcoin..
For now bitcoin is growing and looks growing stronger than before many stores online are accepting it and developers of bitcoin will stay develop it..

Yeah I agree with you, because the current bitcoin is becoming a thing that can not be destroyed. But the possibility is always there in my opinion, because out there bitcoin has many enemies who are ready to knock down bitcoin when there is a gap. But I think it will not happen any time soon because I do not want that to happen. IMO

The fact that it has been opensource and received numerous attacks over the last 7 years without being compromised is encouraging. What I am most comforted by is that the core devs are so conservative that they will protect immutability above all else which is good for the security design.

Since it is in the world wide web then it is breakable. I think someone must have seen it but wont do it with the fact that he could get arrested anytime or might be even put to death. So much money is being talked here so it cannot be done by a single individual who knows the risks of breaking it.

it is definitely not breakable, bitcoin can come down only because of two things, either satoshi has to start selling his coins or internet has to disappear

let us say that the internet is down for 24 hours everywhere. i guess bitcoin could without problem start running again after the break.

yes it is..because of its consistent stability

I wouldn't call it stability, but it definitely has resilience. The community has been strong for a long time and there are always people showing up yo keep it alive, and it is probably far more rare to see a point where Bitcoin isn't being actively talked about or bought within the community. I know that's a pretty biased sample, but it is relatively accurate.

In my opinion i would be detrimental to any of the main stakeholders of bitcoin to force through a chance in the protocal, it could cause a split and would lead effects from which bitcoin would never recover,  a high level of consensus is always better

i really dont think so nothing is unbreakable think about it

Why's that a terminal problem? The price would take an enormous beating but it would also clear up one of the things that lesser minded people believe hangs over Bitcoin and terrifies all of us to tears when we're alone in bed at night.

Bitcoin has been through obstacle and and a lot of beat down, but up until now bitcoin is still standing, this is because of the user who keep on supporting bitcoin, bitcoin is not unbreakable, the life of bitcoin is determine by the support of the user, so if the user stop using it then bitcoin will break

We can't say that Bitcoin is unbreakable because nothing is permanent, maybe one day if the price of bitcoin gone down, many of us will leave and maybe there is someone whats to break it even if this will lead him to go to jail or even lead him to death because worldwide is in the business and he will gonna break it? LOL

The risk of Bitcoin,
1. Someone else invented a better coin and everybody stop using bitcoin for the better coin.
2. Nobody is mining Bitcoin and network die down.
3 someone buys all the coins and everybody hates him, and stop using Bitcoin

I don't think it's breakable, if it hadn't been broken till now with hackers and people trying their best to find exploits to it, the biggest things was the "Maleability" or something like that and it did not break bitcoin and I doubt something better is being made.

at the moment it is unbreakable but as technologies evolve it might be possible to do that in the distant future i think

I agree that bitcoin got firmed base in global market and it adopted by gaming platform makes it so unbreakable.
As we can see that bitcoin keep growing year after year and the price rise and fall but get more tough, as long as bitcoin used worldwide and more famous it's really unbreakable.

Yeah, it could actually solve. because the bitcoin currency outstanding and could provide comfort or facilities that are far better than any other digital currencies. I'm sure in the future growth of the bitcoin is absolutely superb and will provide an excellent profit

That was a SuperWay to say it! I couldn't have said it better my self.  ;D

True, it might be one way that very super to say it. But I see that the growth is very remarkable bitcoin, so it is no longer a word but a proof I've seen it myself and felt by all those who use the bitcoin. The market is very profitable and also bitcoin is dangerous, because we must remain focused and are forbidden to slow

where do you see the growth? because i don't see it? yes, if you read bitcoin news there are many new companies, but also many companies that started yesterday don't exist anymore. i would rather see fewer new ones and longer in business then the other way round.

In simply bitcoin is not breakable by anyone or if we say for a hacker it has highest lecvel of security but yes if the whole community wants a change than they can implement it maybe

I think even community can not change bitcoin anymore because its already use and many people are still adopting it we can not change it many people are saying that they need to change bitcoin to the same as paypal with reverse payment but they didnt do.
So bitcoin will still stay the same as before so bitcoin will unbreakable..

though it wouldnt be a hack then to be honest, in my opinion bitcoin is really unbreakable and no one will be able to do that in upcoming decades

What do you means the hacker with the highest level of the security?LOL, the hacked just breaking a software like a wallet, is always possible for bitcoin getting a break by everyone,every thing and every time. do you mean bitcoin is having an eternal life? LOL

Nothing is unbreakable, but everything can collapse over time. Bitcoin is no exception.

of course it is unbreakable right now and it will continue to be like that because we still dont have powerful enough computers

I don’t know enough to see for sure but so far it doesn’t seem like it is. We’ve seen people talk about crashes but we have never really seen any. I will admit that I did think bitcoin could crash about a year ago. But, as of now, I don’t think bitcoin will be going away anytime soon.

of course bitcoins are unbreakable, in my opinion it is impossible to be destroyed and it will surely remain like that in the future

Yes bitcoin is really unbreakable because bitcoin is very stronger and no one or other currency take over the bitcoin bitcoin is very useful and very safest and secure and people strongly believe in bitcoin .

Tell me where from the bitcoin is can't be unbreakable i think it's always can be break for anytime. just waiting about your reason.
