I agree with everyone here that Binance is maybe the most safe crytpo CEX to deposit funds on for trading. I trusted also FTX since it is now the 2nd crypto exchanges by volumes and they have top notch security as Binance.
No centralized exchanges should someone have a rest of mind that it is safe, Binance is centralized and require full verification which you will need to provide your ID documents and other personal information. If your data is leaked (which is possible), is that safe? Data leak is common on exchanges. Also best to not leave your inactive coins on Binance or other exchanges, move it to a reputed noncustododial wallet instead which you have full control over. Any centralized exchange can be hacked at anytime.
I don't know the other ones very much and how much they can compare outside of the safety of the deposit. I would appreciate any additional insights on that.
According to Binance, FTX is the third ranked recently while Coinbase Pro is the second ranked.
1. I know full well that Bitcoins is best hodl out of exchanges and a lot more secure when control by a personal private key. However, a derivative market on a CEX is needed to trade options. I heard some projects are working to offer derivatives on a DEX in a near future with lightning but the software is not there yet.
2- FWIW FTX is actually 2nd by open interest & trade volume on CoinGecko for the derivatives market:
