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?
These 20% or 25% discounts really matter to both high volume and occasional trader? I mean neither of them will not mind these small differences and must be going with reputation of an exchange and obviously liquidity reasons.
I mean, if I were a high volume trader, I will not switch exchanges just because new discount in trading fee from a new exchange. Even an established exchange offers huge discount, I may not switch 100%, but may start testing for new pairs and for back up reasons. For a small trader, these discounts are nothing, I believe they will not risk with new exchanges unless their trading pairs are available with reasonable liquidity.
Overall, for choosing an exchange, I believe trading fees are playing very insignificant role; availability of particular trading pair and liquidity are prime factors here.
