everything is hackable so it is the same with bitcoin. Just recall the memories on MtGox, then recently fraud with KOrean exchanges. The point is that anything with internet connection is vulnerable. People need to understand that the smartest thing in crypto is to invest amount that can be lost. Risks are evident in cryptocurrency trading.
Bitcoin is available on internet because its a digital currency and hackers also using internet for hacking but Im quite sure that nothing will happen to bitcoin because bitcoin know how to fight against all kind of forks and challenges in past bitcoin defeat a lot of challenges and now we can see that how bitcoin is secure so bitcoin is very strong in market and I know it will become more strong than ever and its price will go more high.
