I wanna discuss about this case, why the centralized exchanger is really easy to be hacked? Whats wrong with the security level? Whether they dont use email confirmation or Google authenticator, etc for their security?
They are not hacking exchanges with email hacks, so it makes no difference if they have 2FA or not.
Centralized exchanges are usually holding coins in hot and cold wallets and hackers can steal coins from hot wallets much easier.
Security breach in Bitmart case was probably leaked private keys for one of their hot wallets, but it's crazy decision to hold so much coins in hot wallets in the first place.
Regular users should NEVER hold coins on any centralized exchanges, that should be used only for trading.
