Passing KYC verification on a centralized exchange is one thing but leaving your assets on the same centralized exchange is another, some people do believe that passing KYC have guaranteed the safety of their assets on the exchange, don't stress yourself OP, many people still leave their assets on centralized exchange till today, they don't learn from the FTX and other crypto companies demise.

I always wonder why centralized exchanges are still a big thing after everything that has happened already, since sudden collapses of big crypto platforms have been happening since few years ago, MT GOX was a good example.

Do you know how many US citizens that leave their Bitcoin on Coinbase? I mean the number is pretty high, for them Coinbase is the safest place for their Bitcoin, they will rather trust a human like themselves instead of trusting Decentralization, there is nothing anyone can do to make them see reasons, they are all using Bitcoin wrong and I don't care if they lose their assets.
