I'm sure that no matter how hacked they are, we can't really blame them because it's certain that in an exchange to store users' assets, they always prioritize the security of their users' assets from hacker attacks. At least they put 2fa as the main security for their account it must be layered again with security in exchange it makes security layered. Unfortunately hackers always find any way to break it all, there are always loopholes in every security. Even when you say exchanges in your country have insane security that they can hack, this is actually hard to understand, but it's a true fact because I've also heard of major exchanges getting hacked even with high security.
