Its no longer news that an ICO in Japan has lost over $400 million to hackers. They promised to pay back investors who invested in their ICO. Thsi is a huge loss. After I read that news, I began to wonder. How safe is Bitcoin and Other altcoins? What measures should we take to avoid being hacked ?
The fact that cryptocurrency is computer base and involve billions of money then I am sure that those skilled will surely target the cryptocurrency this is why the assurance of your wallet safety is quite low regarding security.
I think that's the reason why bitcoin and cryptocurrency called risky.But i have strong believe in block chain security i think no one can break it. I fell comfortable with this security.
