Centralized exchanges are already working hard to improve their security defenses. But the security of the exchange has been attacked by hackers all the time.
Don't think of exchanges as banks, they are not a match.
The "absolutely safe" centralized exchange should not have appeared yet.
I still don't get why people still treat exchanges as wallet. The name "exchange" clearly tells us what it should be used for but still yet you will still see those that still leave their funds there even after they are done with their trade or whatever it is that they used they exchange for.
Now my question is how hard can it be for someone to withdraw from an exchange? Is that they're scared of non-custodial wallet or what? I just don't get it.
