The funniest thing about the whole story is even after this there are people that will still store their coins on a centrallised exchange all in the name of it's safer. I think it's actually high time people saw the bigger picture about what privacy and ownership of coin is all about.
It's not a first time ever a centralized exchange has problem with operation and user withdrawal. Many exchanges died, collapsed, scammed in the past, and people still don't want to learn this lesson and change their practice with their coins.
It's true with senior and experienced people in this market, and with newbies, it's more serious problems practically.
I agree that such cases are very helpful for people to feel fearful and change their practice in bitcoin storage, but it's not the first time.
Choose open source, self custodial wallets for storage. Remember to backup wallet, test backup to make sure it is usable for recovery.
No matter how many times they are warned, people will still store coins in exchanges until they are 'bitten'. That seems to be the eternal lesson.
