Is Bitcoin really unbreakable?

[vdotcash]

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).

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.

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.

[Senor.Bla]

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！！！！！！！

[Tasssty]

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.

[mikehersh2]

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.

[marketone]

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.

[richardsNY]

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.

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.

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

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.

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.

[Superways]

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.
