there are a lot of things that could be said here. But for now, I will stick to this. And the answer is this, No there will never be any safe centralized exchange.
KYC is not in not safe in any way. KYC is a tool and process set up by the government through the centralised exchange to checkmate Crypto trading activities which before you sign up with any centralised exchange, you will need to agree to their terms and conditions which includes them giving your details to any third party by law when the needs arises. So therefore upon giving them consent, you already agreed to them using your details for any thing and I will not be surprised if they trade people's details for Money because they have it full in their possession and come to talk of it, you as a client don't know what is going on with your details your shared with them all in the name of kyc which makes it very risky. Initially, this was not the plans of Satoshi Nakamoto for bitcoin but the government which we have been avoiding has made their way in by including kyc which they are in for. With kyc on exchanges I do not think there is anything anonymous anymore and this is not safe.
