What do you think Bitcoins biggest vulnerability is?

The social/political attack vector. The 2x fork attempt by major Bitcoin companies and Bitmain in 2017 may have been child's play compared to future attacks. Next time, it could be governments or Wall Street institutions that are trying to fork and co-opt the protocol.

I think it's the restrictions put by the government , if it had been a open community it would have flourished in no time but unfortunately the banning and other rules and regulations put us at a disadvantage , there are countries mimicking other countries in banning Bitcoins and all.
 Then comes the factor of volatility because even right now people are afraid to invest in Bitcoins seeing the price chart , had it been a little straight , it would have made more people interested in it .

Government protest against bitcoin, they see bitcoin as a big threat in the financial system issued by them so bitcoin is more likely to be attacked by the government sooner or later.
This is another weak spot of bitcoin this is the main reason why many new investors won't come in when they see how hard bitcoin falls after a pump and how quick it happen that they might lose millions in just seconds.

Bitcoin is never perfect and expected it to be as such is just dreaming. As far as vulnerability or weakness can be concerned, I would like to zero in with its scalability issue which directly affect the speed and cost of doing transactions. This has been a major issue since I can remember dealing with Bitcoin and until now there remains to be no generally-accepted and implemented solutions though there seems to be no let up in finding ways and means for this big challenge. We are hoping that soon Bitcoin can already be comparable to other popular financial platforms in terms of speed of doing business so we can easily attract more and more merchants and entrepreneurs to the Bitcoin ecosystem. Without good solutions, Bitcoin adoption can have a big slowdown.

In the eyes of many merchants, the sometimes extreme volatility of Bitcoin is a big factor why they are shying away from joining the Bitcoin club. Though of course, there are now many ways (and platforms, as well) to ferret out remedies on this regard. However, volatility is something that many traders will not be afraid of as it can be an opportunity to them.

Just recently, there is a big buzz on the announcement by Google that they already developed the supremacy in the field of quantum computing so that a lot of us in the Bitcoin community expressed some big concerns on how this can be affecting Bitcoin and cryptocurrency. As of now, it remains not yet clear if the one possessed by Google can indeed fry Bitcoin and how it can change the dynamics of the whole thing. We are hoping that eventually Bitcoin can be able to withstand this possible threat and that developers can be able to counteract this technology effectively.

If you believe the headlines, quantum computing is a pretty big threat. Maybe not today, but in a decade or three.

I'm aware that we can switch to quantum-resistant cryptography like Lamport one-time signatures, but there is an equally large problem that's gone unaddressed: What do we do about the several million BTC that will remain vulnerable because they are still in ECDSA-secured pubkeys/pubkey hashes? Like the Satoshi coins......do we destroy them?

If not, millions of coins will get stolen and dumped on the markets for years and years. Being a HODLer sounds like a nightmare in that case!

Its volatility could be called as both a strength and a weakness. Cause people are afraid of how it changes so much in just days in the market and yet thats how most bitcoin owners profit, because it's close to unpredictable. There's also the factor that government refuses to accept it so the masses also adopt to the same policy. Those that are ignorant of the benefits of bitcoin or crypto that is.
I wouldn't really say security as a weakness since that's always a part of a system and the community are striving to improve it anyway so I wouldnt really count on itbas its weakness.

FUDs people are easily affected by fake news that cause them to lose their trust on bitcoin also when people outside this industry after hearing a fake news they just talk too much without knowing what it really is.

and on the other side the
The social/political attack vector. The 1mb base stagnation apartheid by major Bitcoin companies and devs in 2017. it was Wall Street institutions that are trying to stagnate and segregate the community and co-opt the protocol.

(1mb=controlling the protocol.. aparthied/segregation= throwing the non COREperate opposition off the network)

yes Barry silberts company that owns most major exchanges of influence and put millions into the dev teams pockets to try innovating a corporate orientated network of hubs and group management which doesnt even use blockchains and requires people to lock funds into custodian co-managed scripts. thus not only avoid using the bitcoin networks security for payments but also reduces peoples self control and sol ownership of funds.

thus making bitcoin appear to be by their actions, not useful and not something that will innovate into something the world can use because those BScartel people want people to use their other networks instead. thus strangling bitcoin.

just remember how bank notes turned out once banks started messing with the 'gold backed promissory notes' that replaced actually using gold. yes even tether recently shown the futur of what can happen once people are STUCK using millisats(altnet(LN) token) instead of real btc

no it is not. because we are many decades away from quantum computers becoming a threat to be able to solve ECDLP. but so far the media (specially the bullshit bitcoin related news sites that are desperate for articles) are making it into a big deal and trying to spread misinformation.

Bitcoin’s biggest vulnerability for me is  security. Given that this is used as source of income or even source of payment for sure there are a lot of ambitious people who will hack and get something from our funds. Hackers and amscammers are known here so for me security isthe biggest vulnerability on bitcoin.

Government restrictions is the only thing I can think of that can possibly stop or make bitcoin transactions made hidden/underground. Speaking of security and anonimity, bitcoin and other cryptocurrencies solves almost all issues. The problem lies to that main advantage, anonimity, since there are no one to have your back when someone stole your bitcoin or no one would be able to trace payments made for illegal activites such as crimes.

We cannot question the security of bitcoin, security is coming from its own owner. even in fiat, security depends on how you take care of your own money, even if storing in banks, there are some cases that you might lose it if a scammer will find a way to get your money by getting information of you account.

I might consider the possible lost of private keys, which you wont be able to recover once you have lost it. There is no private institution that will give you an assistance or an account which you can easily forget your password and reset it to a new one.

I guess I share this idea too and must give emphasis to it. Bitcoin being open sourced was one of its strengths and at the same time also one of its weakness - thus the possibility of being forked by anyone with enough computing resources and in effect leaving the main network less secure!

Also, we must  consider one of its vulnerability as what SN had anticipated - a 51 percent attack at which point could become scary and a possibility once Governments try to intervene and dedicate their resources to it and take over the network.

Researchers recently identified vulnerabilities in cryptographic signatures for Bitcoin, Ethereum, and Ripple, that allowed attackers to calculate private keys and, consequently, steal any crypto in that wallet.  Vulnerabilities only occur in edge cases where code is not implemented by developers properly, or likely occurred because of faulty multi-signature hardware. The research emphasizes the resiliency of the cryptographic schemes used by cryptocurrencies, as well as highlights the importance of proper implementation (Mitchell Moos, 2019).

For now, I'd say the government is still Bitcoin's biggest vulnerability, whether through heavier regulation of on and off ramps, or through straight up investing billions in mining to ruin the whole infrastructure.

If bitcoin keeps growing at the same pace, in a few years not even the governments will be a risk for bitcoin

I am going to say that the investors is the bieggest vulnerability when it comes to Bitcoins and when i am talking about the investors, I am going to be very specific and say that the newbie investors and those that are very quick to sell their cryptos whenever they see any negative rumor regarding bitcoins and they proceed to sell their butcoins and this in turn leads to the price crumbling down.

it probably is price and the related dramas that it brings. otherwise every other aspect of bitcoin that you think about is very strong. it is decentralized, boarderless and it has been resisting all kinds of attacks for 10 yeasr without faulter.
but when it comes to price we see a lot of drama mainly because the market is small and filled with a lot of newbies weak hands that could easily be manipulated to make irrational moves.

I may agree with this on some points because there are some countries right now that banned cryptocurrency in their own country for some reason which is a bit frustrating because they don't know what Bitcoin can do and how it can help them but... there are more countries who accepted it compare to those who banned it.

Maybe the FUD's that are spreading in the internet and the ability of the whales to manipulate it are its biggest vulnerability. Bitcoin can be easily manipulated by different whales if they want to. They can sell if they want and buy if they want. I'm predicting that in the next years, more and more people will be using not only Bitcoin but other cryptocurrencies and the chances of it to be manipulated will decrease slowly.

I agree. Price movements can hurt Bitcoin, I think. Anyone who does not believe in the future of Bitcoin puts risks at the forefront of any price fluctuation. I think the price is more effective than the real vision of Bitcoin. For this reason, many countries are far from making legal arrangements on this issue. However, this price activity may also be reduced by legal regulations.

The wrong impression people are giving against bitcoin. Most of those people includes the government and people who give doubts to bitcoin. Government is a powerful sector that can give wrong image to people that may cause fud.
Just because the nature of bitcoin is decentralized and volatile, they're using it to bring negative impression on bitcoin. It's always the people who can give vulnerability towards bitcoin, because they're using its nature to attack bitcoin, where in the very first place bitcoin also have its cons.

To me is a big company that everyone knows their name
They have a lot os BTC, they support a fork of BTC saying that BTC was not the original one, they have tons of Asics, and they can do a massive atack to BTC

To me that is not such treat than this

a mining 51% attack is no threat.
the reason being is that miners cannot change the rules of the network.
imagine the 'attack' as a 100m race. yea on athlete has more speed and wins more often.. but its the officials that then test his blood and urine, notice he is on drugs and disqualify him for cheating.

however
take the 2017 event. it was the devs that FORCED a network change by saying unless miners follow the dvs new rules on a specific date, the miners will get thrown off the network.

the only fear of a mining 51% threat is that they blacklist certain transactions. as all other fears can be coded out with just 2 lines of code. and even if they start making blocks without transactions. that too can be coded to reject blocks that dont have tx's

 the real fear is the devs

One word, "Misinformation"  >:(

You get people who know very little about Bitcoin and they are influencers with millions of followers and they go out on social media to bash Bitcoin with their nonsense. The latest one was Mark Cuban with his "I would rather invest in bananas than Bitcoin" comments on social media. A guy like that is the typical "know it all" rich brat that wants to tell everyone what he thinks is good or bad, but he hardly knows anything about the topic that he is bashing.  ::)

So the sheep following him believe this crap and follow his opinions like a slave obey his master.  >:(  Luckily for us, there are some influencers out there that actually do their research before they say something about it on social media and they do not make a ass out of themselves.  ;)

Government would be bitcoins biggest enemy. Regulation prevents people from getting involved in crypto, thus preventing cryptocurrency's growth and adoptation. Some countries are skeptical and strict when it comes to their people getting involved to it due to scam and issue that crypto is used in illegal activities.

The cut of internet connections, we know this is possible because I already saw on the news that one of the places in India got their internet cut off by the government so that they cannot publish on the internet about what is going on out there.
So, what if the internet will be cut off in your area? because of the disputes between the government and its opposition. this is what we called unexpected or sudden happening. if something like this would happen you will lose access to your bitcoins and you cannot get it back until the connection will be brought to normal again. or what if the internet won't come back? then its time to say goodbye to your bitcoin.

Yes, in fact most of the first page of this thread is precisely that, except for Franky's intelligent comment.

Most comments are about government fear. Let me spell it out for you: Bitcoin being banned worldwide would NOT stop it. It was designed to withstand that, and it was expected they would do it, but they didn't. There are far more countries accepting or tolerating Bitcoin than those banning it (about 15).

Someone even mentioned security. SECURITY? Bitcoin cannot be hacked, it hasn't been in 10 years, and it won't be later. This is also one of its key design features, you cannot tamper with the blockchain, and the theoretical 51% attack is a form of brute force attack, which is deterred by the fact that it would cost more to pull out than the possible gain of seizing the blockchain at that point. This should be obvious, but attacks to exchanges, online or personal wallets, are not Bitcoin's fault. Its each of these people's field. And in those cases, you have to talk about "hack" to those specific things, not Bitcoin. There are historical cases of altcoins being "hacked", and that should give you a fair example of what happens when things are not done right.

Since Bitcoin is invulnerable in code, it can only be harmed cosmetically on the outside, with FUD and lies, something that doesn't directly really affect Bitcoin, but the humans that would or would not use it when being misled like that. Bitcoin is working as intended despite that. Same thing as when governments "ban it" instilling fear on their people, but Bitcoin is still working fine even in those countries, you just have to cover yourself better.

I think the bitcoin's very dangerous vulnerability is a huge accumulation by one entity that will going to control the market in the future. That might seems impossible but there's a chance that a very rich investor might spend his entire investment to bitcoin. As a solution, I advise my colleagues to accumulate as much bitcoin as they can while it is still early.

it's not a vulnerability per se, more like an unknown---the viability of a hard capped supply secured only by transaction fees. i really hope we don't wake up to plummeting hash rates a decade or two from now because block rewards aren't covering mining investments.

this is why i tend towards the "small blocker" camp, out of an abundance of caution re mining incentives.


not increasing the block size enough for you is now apartheid? quite the colorful language there, franky. ::)

The only vulnerability of Bitcoin I can possibly think of is the collapse of blockchain technology and the internet. Blockchain technology is no doubt the backbone of Bitcoin and cryptocurrency in general. If Blockchain technology is eliminated or destroyed, Bitcoin will have no value since it solely operates a blockchain network..

Currently the biggest vulnerability is the possibility of 51% attack.
I have red in several sources that  allegedly China has more than 50% of mining power divided in several locations and by different companies, this would mean that BTC is extremely vulnerable.

It really all depends on where in the timeline. Quantum computing isn't far enough along to be a threat yet. Also I believe the way it computes data would have to be adapted to hack the blockchain. However apparently this form of computing is fast enough to see the private key as it is revealed briefly for every transaction.

It seems to me that now fear for the future of Bitcoin, in principle, is not necessary. It is needed as a means of earning and means of manipulation. The big danger for Bitcoin seems to me is that as soon as it ceases to be needed by people with money, it will cease to exist. But the probability of this is very small.

Actually, Barry Silbert was on your side, trying to push the NYA (2x fork) down our throats. ::)

The developers did no such thing. Bitcoin Core has never attempted to merge changes that would break Bitcoin's consensus rules -- Segwit certainly didn't. Therefore it's ridiculous to claim they "co-opted" the protocol.

Do you really think Core has an obligation to implement every terrible consensus-breaking idea you want?

You can call that stagnation, fine. But if anything, refusing to split the network by hard forking kept the community together. Instead of a catastrophic hard fork network split, Bitcoin Cash just peacefully splintered off. It was the best possible outcome to a 3+ year impasse.

FUD is the problem of people who are unable to analyze and check information received from media resources. FUD is not a bitcoin vulnerability

Bitcoin's vulnerability is that it is very volatile. Big players can create price hikes and speculations, this is a terrible minus of this digital coin

I believe the biggest vulnerability for Bitcoin is not that it will be hacked/attacked, fought and smeared by gov. forked or co-opted. The biggest fear is that after the world finally understands Bitcoin,  there will not be enough people who care.

Susceptibility towards political control IMO is the biggest vulnerability of bitcoin currently. We may have seemed to get past the horrors of malleability, 51% attacks and other technical complications that could arise in bitcoin that the last thing to ever cause it some problems in the future is the people who runs the show, or the people who have large control over other people in this decentralized network of computers hashing to mint money. Accept it or not, there will be assholes and greedy scums who will walk the scene with their ever-so-malicious intent of just making money and nothing else for the good and development of crypto, and to me they are the worst enemy of bitcoin, and not the technicality per se.

Government and regulators will always remain as enemies to bitcoin or any other crypto currency due to the fact that they cannot control it and it's decentralized but off-late we have come across situations like kidnappers, hackers demanding payment through bitcoins and claims that bitcoin is used as funding for terror activities and security services cannot track their activities is turning out to be a worst nightmare. But there are crypto friendly countries like Malta, Estonia as well who have seen the bright side of crypto world.

It is not that easy. Political control of Bitcoin is just a theory, it cannot be executed at all. Do you really expect government to go to the doorstep of every miner? Anybody can mine crypto, I don't see governments of whole world coming together to not allow their citizens to mine bitcoin independently. Well to make it full-proof control, every single country has to join hands, isn't it!

I think its biggest vulnerability is how hackers are having a field of day and easily stole millions of bitcoin in big exchanges and from individuals the recent hacks had absolutely send a wrong signal to potential investors both cooperate and individual who are afraid of possibly becoming a victim, hackers sophistication is absolutely sending fears into cryptosphere consequently posing a bigger risk to investment.

Governments and regulation are not enemies of Bitcoin, stop thinking like a child. Positive regulations and legal framework are the only way for Bitcoin to get further developed, adopted and incorporated into financial and economic system. And that doesn't mean the end of decentralization.
For me the biggest vulnerability of Bitcoin are its users that often with reckless and unmature behaviour make damage in the market.

I think a lot of people have perfectly stated it in the past post in this thread. It's not Bitcoin itself that has the problem but all of the external factors attacking it that leads to FUD and agony in the market. What I'm talking about is the fake news being spread, the government and its uncertainty for the future of the industry, and again the misleading information being spread making most of the people into the industry go down in shambles. Without really the negative things being spread for Bitcoin and the industry I think we have gone far by now in terms of mass adoption and acceptance by the general population. But this vulnerability I'm talking about doesn't have any solution at all as this couldn't be avoided and the best way to battle it really is to hope that the trust will outweigh the negative things surrounding the industry.

That's a fair point, but it seems like a necessary trade-off. Hard forks coordinated by miners and developers break consensus and economically coerce users into forking. Working within the consensus rules to achieve backward compatibility was one of the legacies Satoshi imparted, and I think the model he left us is quite elegant:

Bitcoin do not have any specific vulnerabilities you can directly point and say this is it.  Some financial organizations and some government authorities  have tried to bring Bitcoin down but haven't had any  success doing that. This shows that Bitcoin has no specific thing that can be used or described as bitcoin's vulnerability....  If it did like bitcoin would been dead long time ago...

In my opinion, it's the consensus algorithm, it can't really be changed, too late I think. It works of course, but not as efficiently as some of the latest consensus algorithms used for projects today.
  I still don't think a true Bitcoin 2.0 has emerged yet, but I believe that one will someday.
  

Technically, I don't think there is any vulnerability or at least I didn't here of any.
But if we are going to talk about weakness then my main concern is the user himself not Bitcoin as a technology.
10 years passed and people still find it hard to use it and still make silly mistakes like losing their private keys or not knowing what an unconfirmed transaction means.
Moreover, people are not ready yet to become their own banks.

Maybe its true, users are the main vulnerability of bitcoin. many users are just thinking of making money and that will also lead to an individual to scamming other people.
At some point, we can think of the government will help bitcoin community as they regulate it. There are positive and negative things about it. The positive thing is, government might be the solution to decreased the crypto market's problem to scammers, if we have the help of the government that will regulate every project everything will be filtered.

Future fork attempts, we've already seen how forks like Bitcoin Cash and Bitcoin Gold (to a lesser extent) have almost split the communities in different groups, and those forks where run by just a single company or a person behind it.

Now imagine if the government started forking BTC for their own use, things would be extremely hectic and our community would likely get torn apart, and forms of BTC that where less decentralized, and more controllable could be created and become popular.

I think so, if a lot of people say that the vulnerability of bitcoin is a banned authority, its bulshit because in my own country there are rules that prohibit the use of bitcoin and I don't have any difficulty using it? that's the advantage for me not to pay bitcoin taxes. there is no bitcoin vulnerability is what makes many governments fear, thats the fact.

One of the biggest advantages of Bitcoin is that it is not controlled by any authorities, and this allows its users to remain anonymous, although their transactions are visible to everyone. The anonymity of the owners is a significant reason for the growth of Bitcoin in the last couple of years. However, it is also a vulnerability as this anonymity can also contribute to fraud and other crimes. If governments around the world introduce standards that make cryptocurrency difficult to trade, its price will drop.

A number of Bitcoin Cs exchange exchanges have weak supervision, conflicts of interest, and lack of consumer protection. many virtual currency platforms do not have the policies and procedures needed to guarantee the fairness, integrity and security of exchange markets.

In my opinion, I think bitcoin's vulnerability is its decentralized nature and the volatility of its price. If we are going to look at its history, bitcoin has been illegalized by plenty of country before making its progress go short and at the same time, its volatility made many investors leave its side whenever there's a huge fall.

Though Governments are restrictive on Bitcoin usage. The use of cryptocurrency is difficult to fight going forward. Traditional mediums of exchange and financial institutions ought to revolutionalize and improve on core conveniences and efficiencies provided by Bitcoin both as a medium and investment option.   

The biggest vulnerability of Bitcoin lies not in Bitcoin itself, but in people who use it and who invest in it. Most of them don't understand(and don't have time to learn) how Bitcoin works, and so they are fast to believe in the "quantum computing threat" bullshit and such. I mean, firstly, quantum computing, if it ever happens, will be a threat to the whole world, not only to Bitcoin.

"The quantum computer could also break all the encryption keys on all the nukes in the world", as aantonop said in one lecture, so the possibility of breaking Bitcoin would be the last of our concerns.

Secondly, Bitcoin protocol can be upgraded to resist quantum computing attacks.

Yet, people read about the "quantum computing threat", and start selling like crazy.

Three things, being open to internet, government, and it's volatility. Open to internet is a pros, but can also be a con for the reason that it can be open to hates (which is inevitable) and can misinformed people. Second is the government where they put restrictions and regulations because they see bitcoin as a threat. Lastly, it's volatility which is its primary characteristic that invites traders, but sometimes it also holds potential traders due to the fact that they can lose much money overnight.

How is that different from what we see in the legacy market? Do you think every single brokerage firm plays by the rules? They pop up everywhere without a license and go bust just as easily as it happens with crypto exchanges.

We can choose between exchanges in crypto, which means that if you do your research, you won't be transferring any fiat to HitBTC or OKEx, but use Coinbase or Bitstamp instead.

You can't and shouldn't expect to be helped everywhere by consumers protection. If you mess up somehow, then it's your fault entirely. Even if they offer consumers protection , the main job everywhere is to not pay you out.

Still, I see a big problem, which depends on bitcoin itself. It is practically impossible to further significantly scale bitcoin. The lack of good bandwidth will limit the possibility of further liquidity of Bitcoin, it will not be used so massively even in comparison with altcoins or stable coins. Even now, the stable USDT coin has exceeded the trading volume of bitcoin in trading volume.

From my point of view, Bitcoin is very vulnerable in terms of regulation. Because there is nothing to regulate Bitcoin, many people who want to use it to control BTC. And Who is that? Ie people who have large capital to manipulate the price of BTC and control the market. And those who claim to be the creators of Bitcoin are only for personal gain.

When you don't have proper acceptance toward the mass people then you can't flourish yourself properly, it's just not a barrier it's a major issue that is playing negatively within this platform. still now, a lot of countries are keeping away from this Bitcoin and cryptocurrency, there is no positive news in recent time for the purpose legal establishment and it's the main challenge to be stable for a long time, I think this factor would play as fear role among the general people who have more or less interest regarding this platform. also volatility is the main concern of this platform and there are no remedies of this issue, in recent time, there is some big fish company is creating its own cryptocurrency, so in this way, Bitcoin could be accepted gradually, I believe that without acceptance, you can't do a lot.

I think the idea of being a government's threat and the bank's enemy is one of its vulnerability. If the government would see it as an asset I'm sure that there will be a massive adoption and Bitcoin could be used as a currency freely in every country. Volatility is its vulnerability and strength at the same time. The good thing is Bitcoin despite its weaknesses still able to rise and reach good popularity.

If you talk about the biggest Vulnerability of being a digital currency "Bitcoin" it's easy like: anonym (many people don't like anonymity), fees become more expensive, price fluctuations tend to go down and some other features that make someone's perspective say the vulnerability of Bitcoin. here I realize that every time and every growth, the lack of bitcoin will always be different, so the point is that the lack of digital currency is very dependent on the perspective of many people and also the current market conditions.

Scammers. I can't wait for a universal policy to chase all those scammers and their scams out of town. Only then the billions of dollars getting spent on these scam ICOs (https://www.cryptozink.io/icos-stos-ieos/) and fake blockchain projects can come to the real projects. The 10% that will survive.

The government is scared to adopt bitcoin because of its volatility that will defeat the banks when it comes to the profit that the user takes. And we know that banks are connected to the government, thats why banks are trying hard to manipulate government decisions in order to not be legalized or to be introduced to the country. The worst thing is to ban cryptocurrency by the government.

Some countries accepted bitcoin and some didn't check it here : https://www.investopedia.com/articles/forex/041515/countries-where-bitcoin-legal-illegal.asp

The only vulnerability I can think of is the restriction of government towards bitcoin that is why the transaction regarding with it is limited to those countries where crypto is available. This restrictions hold the bitcoin from being widely used across the world.

Yes the restrictions are the only vulnerability for bitcoin because the price fluctuation and volatility is the part of crypto world. I believe there are alternatives available to escape from the restrictions, on the other hand restriction will be there for all the crypto currency in those countries which does not entertain bitcoin so it's a collective issue which turn out to be vulnerable for the entire crypto market. True vulnerability is something which is created by whales wherein they can control the price to an extend.

The most challenging thing will be:

When the privatekeys of the lost coins with no owners - 'shalecoins'  https://bitcointalk.org/index.php?topic=5134441.0 - will be 'fracked'.
The first group will then sell all these coins because they will then know that it is possible to get the privatekeys and that others could 'frack' them. No matter what the BTC price, they will sell them.

There are more than 1,000,000 'shalecoins' with a 10+ billion US$ value. So we can expect that there are private groups who want/try to build a supercomputer.


https://bitcointalk.org/index.php?topic=5166180.0

i think lack of government backing is its main vulnerability as many people out there who use crypto were its not legalised use it in hiding.

Possibly the crypto ecosystem having many versions of bitcoin is also confusing and some consensus to put this to an end should come through!

I think Bitcoin's biggest vulnerability is governments. Governments can easily ban Bitcoin and prevent people to use it. So, Bitcoin usage will decrease by that and it will affect the price too of course.

For me, bitcoins biggest vulnerability is attack be the government sectors(prohibition and banning). Some countries already ban bitcoin and another cryptocurrency because of their reasons that bitcoin's giving the criminals vast anonymity in there transactions/ payments. Also, they don't like the capability of bitcoin. The other reason for bitcoins weakness is decreasing acceptance; if those huge companies stop support or accepting bitcoin, I'm sure the price rate will plummet. :)

I think one of the biggest vulnerabilities of Bitcoin is security gaps. There were so many news about stolen Bitcoins. I think before all other problems, Bitcoin must try to fix its security gaps.

I think people obsess far too much about 51 percent attack. it has some kind of attractive mystery to it that distracts people. If you're worried that someone might reorder history using a high hash-power collusion just wait longer before you consider your transactions final.

A far bigger risk to Bitcoin is that the public using it won't understand, won't care, and won't protect the decentralization properties that make it valuable over centralized alternatives in the first place. a risk we can see playing out constantly in the billion dollar market caps of totally centralized systems. The ability demonstrated by system with fake decentralization to arbitrarily change the rules out from under users is far more concerning than the risk that an expensive attack could allow some theft in the case of over-eagerly finalized transactions.

All vulnerabilities with Bitcoin have been patched and no Bitcoin was lost this is including the exploit which allowed someone to generate a lot of Bitcoins. What you are talking about is the exchanges and other online services which have been hacked which is not a problem in Bitcoin itself. It would be nice if we saw Bitcoin services with bank like security but even banks have been hacked in the past...

I think there are two major vulnerabilities with bitcoin which are volatility and decentralization yet are what makes bitcoin sweet. without bitcoin price volatility and decentralization in nature, the governments around the world would never have an issue with bitcoin.

I'm not sure if BTC could ever feasibly get owned by the government or another entity, it was made perfectly so no one can change the code, or increase/decrease the supply, as well as other factors that make it a decentralized package.

Maybe there is a world where a government/someone is able to obtain a large supply of BTC and then be able to control the market, or someone is able to create a fork that is more used then BTC, essentially killing it off. All unlikely, but possibilities.

Bitcoin and crypto have this popularity because of the volatility effect of its price. It isn't surprising how it gains popularity pretty easy cause a lot of big investors have been involved in this growing market. Such vulnerabilities will remain until crypto isn't over and it much more volatile as I think if it was supported globally.

I do not consider governments or regulations as enemies of Bitcoin. I think the main vulnerability is user himself. Not bitcoin, but exactly people are involving bitcoin in illegal activities. Besides not everyone is acknowledge about how does it actually work. We still lose Bitcoin because of such trivial mistakes like wrong address input or losing private keys, seed phrases.

It seems very appropriate to say that the government will not be hostile to bitcoin and its circulation. But they are more synonymous with regulating and preventing abuse.
Violation is an individual or user error, not from bitcoin. It's just that the perpetrators of this abuse use bitcoin to carry out their wishes. I agree with this.

Technically, I really don’t see any, but fundamentally, I think they are the enemies around, the financial institutions, the banks and the government, as these are the people that bitcoin is really against for now, although not completely against them, but not okay with the financial services that they render to most of their people.

We have some governments that would do everything possible to actually make bitcoin to be less used, presently now, there is nothing that they can do again in the aspect of cryptocurrency, and they know they cannot generally control it, so the only way which some of them has been doing is to create their own national currency, and even with their national currency, there is still little chance of people using it because it is a centralized currency unlike bitcoin which a decentralized one.

There's no more bitcoin as the most secure cryptocurrency network... if there's for real a quantum supercomputer. That's the real big problem for the whole cryptocurrency ecosystem, idk if there's any statement backing with some facts that this quantum computer won't really break the blockchain...

It's seems everyone aware that this is inevitable, we just need to accept and prepare for the worst schemes (disclaimer : I have no intention spreading FUD)

The biggest and latest hot vulnerability for bitcoin is indeed  the quantum computer.
Thoughts ? Any refutation on this?
