I mean Blockchain system will never hackable. This system is Causing stir system of the world. This creation is unic and naver hacked.
How you can be sure about that? The creations is unic but that dasn't means hakers could not breack the rules, give it a time and you will see!

I mean Blockchain system will never hackable. This system is Causing stir system of the world. This creation is unic and naver hacked.
I believe that with our technology, no system will be secure. Because sooner or later it all breaks off sooner. There is nothing eternal and stable, except gold.
Security is an involving issue and no system is safe that is any system can be hacked into no matter the level of it security, and in the area of security I will give bitcoin 90% score because apart from the various exchanges and wallet developer's that have been hacked in the past bitcoin it self have not hard any record of hack before.
Satoshi did fix that already in Bitcoin before and it is almost to perfect that it is unhackable, but those new altcoins are not Bitcoin. Their developers need to expand and gather more knowledge about cryptocurrency about the complexity of security and quality services. They may hack blockchain but not Bitcoin. 
It was not a new exploit, some guy got access to over 51% of the mining capacity, and used it to double spend.
Nothing new about that , all crypto coins face it, including btc.
It's called a 51% Attack and Satoshi warned about them.
The really stupid thing is ETC is now worth $2 more than before it was attacked.
So investors really don't pay attention.

In that case, a similar threat to Bitcoin is very insignificant. No single mining pool is having more than 20% hash-power and it is near impossible to get to 51% with BTC. But it may be possible to do that with some of the smaller coins, such as Litecoin and Novacoin.
Just like what they say, no system is safe. Hackers will always find ways to get their way into any systems. However, bitcoin and any other altcoin developers never stop on looking after on their short comings and making improvements and counter measures for it.
You are right. Developers always try to improve their technology. Every owners wants to safe their assets . But hackers are always developing their way or system or technology for hacking.
Eterium should take a nassary step for the fact.But bitcoin is mostly secure better than Etc.my concept Bitcoin is not hackable from blockchain at presents a not looking or hearing bitcoin hacked so everyone should fallow security system.
don't compare warm with soft here
etherium had a lot of vulnerabilities same as ETC
blockchain is not something immune to hacks , since there are money there will always be people who want to steal that money
digital money is no exception , in fact some even prefer to try and steal them because of the grey zone cryptocurrencies are in at the moment
and a relative easy to convert them into cash or transfer
it deosn't mean that bitcoin is hackable , two crap coins attacked - serves them right

We all know tha phrase "No system is safe" they will not say it if its not real,if youre new to hacking issues and you think that blockchain is very secured that its unhackable youre wrong,even microsoft got hacked often so hackers can easily find a hole in your secutiy
You have to compare Apples with Apples, when you make a statement like that. Just because a small Alt coin suffers from a lack of hashing power, does not mean that Bitcoin with huge hashing power will suffer the same fate.
Every coin has it's strong points and it's weak points and so far Bitcoin's code has been rock solid and no mayor breaches or exploits have been found.
Ethereum is nowhere near the same as Bitcoin, so you are not comparing Apples with Apples.

Hey everyone ,
I think that everyone already knows about the recent problem etherum had, when some hackers tried hacking into the blockchain system of etherum and actually succeed, they did overwrite the transaction history and one should remember that the hackers since 2017 have stolen 2 billion dollars worth of cryptocurrency now , so our long said *non hackable cryptocurrencies* are now getting hacked and to all those people out there who really thought that the classic Bitcoin was good enough , I think we should reach a common point now , Bitcoin needs to reevaluate it's shortcomings and then work forward to make enough advancements so that it becomes stronger day by day.
Also no matter how complicated the problem is the solution is always logical, no matter what we do today 10 years later there will be logical shortcomings noticed by some.
It's time for advancements now.

Well there are always great hackers out there that capable of doing such things, all we can do is trust the regulators of bitcoin(US Financial Crimes Enforcement Network) that they would further improve the system leaving no holes for these hackers to get into.
Also what we can do as a community is to protect the success of bitcoin by not abusing it.
Bitcoin is perhaps the most secure blockchain and has never been hacked. Just because there are weaker blockchains out there does not mean their vulnerabilities apply to bitcoin. Now, it's true vulnerabilities in bitcoin have been found, but they've been patched.

The development team of bitcoin is making necessary measures and they are always moving forward to address the issue. So don't say that bitcoin is or its blockchain is hackable because they are different from among other cryptocurrencies.

I think you getting it all wrong. The fact that other altcoin have small vulnerabilities does not make the entire blockchain and bitcoin hackable. Bitcoin and blockchain still remain immutable
That is right. With that idea, it nothing but just an illusion or opinion. That is not that too easy to happen that the whole or the entire blockchain will be hackable. And jus like you said buddy, the entire Bitcoin community will remain and still be immutable. 
I don't believe this. Maybe this is just a small flaw that appears when the code encounters changes. I believe in Blockchain technology and if hackers can do this, Cryptocurrency has actually been destroyed before.

Since its start, every financial sector is abused by hackers. By the time, founders of a financial tool or value work on weak parts of founded sytem and make it protactable to hacker. It is just a process goes for bitcoin, too. It is a normal thing and developers work on problems that we recently have.
a 51% attack is NOT a hack. it is an attack. and it has happened to an altcoin with low hashrate which is not even the first time that this happened. basically every month or so another altcoin is attacked this way simply because they copy bitcoin while not understanding what they are copying! bitcoin works with PoW because it is the only currency that matters and people want so it has the highest hashrate and is way past the point that it has become expensive enough to make 51% attack simply impossible.
First of all everyone already knows most possible vulnerabilities of BTC and we can see if for example blockchain got centralized and some pool is trying to overwrite transaction.
In case with ETH I don't know the details but I guess that was not a hack. If someone got a chance to overwrite ETH transactions then ETH price would drop to zero in a single moment.
About OP's statement about stolen 2 billion. It is also not valid here simply because those money were stolen from exchanges or ICO hacks where. That happened due to unsafe work of 3rd parties that were holding those coins and not because of blockchain vulnerability.
