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 ?
Cryptocurrency is safe enough, but human is the weakest part of any security system in the world, so first of all, you need to be very careful about what you are saying and posting wherever it is happening, they can use everything to get your money!
