Focus more on increasing the profit you make, so you don't have to worry about the fees these platforms are getting.
Fees are important because from a little experience, they are different from one trading platform to another. As a trader just on the exchange, your goal is to make the most profit and minimize any loss that can be avoided. The knowledge of different trading fees on each of the platforms will decide whether to move there or remain where you are.
MEXC has just increased their spot trading fee to 0.05% for market makers and takers. But their future trading fee still remains as 0.02% for takers while 0% for makers. I prefer the exchange if I want to trade futures. You can even set the close position order TP with limit order so that no fee would be deducted if the order is filled.
Do you know how these maker and taker fees on these cryptocurrency trading platforms are calculated? My observation is that whenever I don't use any leverage and I try to trade $100 in futures market, the fee I get charged is above $50 which is high.
