I read the new the Japanese Exchange Coincheck loses ¥58 billion in the hacking attack. It’s not a single case in this after a few weeks ago Etherdelta was also Hacked. So how can we ensure that our money is safe on exchanges?
Hacking is a common problem in crypto-world, even in every aspect of the Internet, there are many cases since a long time ago.
Hackers always targetted exchanges as the biggest prey to hunt as they have big trading volume in their hot wallet, it isn't easy though.
I'm not a hacker to explain how did that happen, but we know it's not safe to keep your funds/coins in exchanges.
Exchanges meant to be a place to trade cryptocurrencies, not a place to keep your coins for a long-term, just deposit-trade-cash out immediately. But for now, I don't think hacking is the big problem, bitcoin acceptance in world-wide a.k.a regulations regarding cryptocurrency is the biggest problem right now. Bitcoin price always falls down if a big country announces will bam crypto trading or bam exchanges, such as happened in China and South Korea.
