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 ?
Before we joined cryptocurrency we already how risky this investment is. The system is operated with computers and uses internet the this is the easiest target for hackers. That is why we need to expect that any security breached to occur.
