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 ?
Crypto is actually really safe, what's unsafe are the companys holding our money.
You are right,crypto currency are totally safe but we have to keep it in a safe wallet for without being hacked.If you keep you funds in online wallets or in exchanges then no one is resposible if that money hacked.
Crypto currencies are really safe until it kept in a wallet with private key access.Yes, algorithm based on which the encryption done for crypto currency is always ensuring (at least so far) the security of our of assets.
Breaking that encryption will not be possible for any hacker in near time as it is kind of searching one particular sand in beach. Some people do claim that quantum computer will be a threat for the encryption of crypto currencies. But we can be sure like crypto currencies will be switching into new encryption model which will be more secure against quantum computers too. So, we never need to worry on this as there are many developers and experts will be working hard to ensure our crypto currency's protection always.
