It appears that you have a different question than the title.
Anyway, if you compare these three exchanges based on their trading fees, they are not too far but Binance seems offering much cheaper fees with 25% promo discount when you hold BNB. Bitget also offers 20% discount if you hold BGB but Binance offers a better discounts. For Bybit seems doesn't have a discount option?

Regarding liquidity, we all know that Binance is the most liquid exchange, so if that is your criteria, I recommend Binance.
