Before the attack on Houbi, many other exchanges have been hacked before even the biggest exchange binanace have faced some potential hack before last year. If Binance can face such attacks, then I see no exchange that can escape that. In light of all this hacks, it is important that the security of such exchanges be improved to avoid those hackers of escaping with this monies hacked from those exchanges. Depending on how your technical team and security system of your exchange is, funds can be frozen immediately as in the case of Binance when it happened last year.
Even though there are still very few trading platforms that have never experienced security exploitation, the recent incident with Houbi should serve as a reminder for everyone to remainattentive and prioritize their security.
Online exchanges are prone to attack at anytime that is why it is always advisable not to keep too much of your funds in those centralized exchanges. Only keep the little you want to use at that time in such exchange or don’t keep any there, but transfer there only when you want to exchange them.
