Avoid those exchanges that are charging 0.5 percent fee, they are damn too expensive, I think you should go for cheap exchanges like Binance that as a fee of like 0.002 to 0.1 percent, this is why you see more volume in Binance, there fee has been so cheap for a very long time and they have never changed the fee or alter it. Aside fee, their platform is very fast, and you will get your orders executed as soon as possible because they have all the volumes needed to do this.

I think we also have some other exchanges right no too that are really trying with their fees, exchanges like Kucoin is not bad, the last time I used them, I think that their fee is still a little bit fair compared to some other exchanges that I have used in the past, but Binance still happen to be the lead.
