You should try binance as many people here suggested to use to trade. I think that will not be too complicated as if you use bitmex because, in binance, you can use the normal trade, and that will different than the margin trading. It is difficult to use margin trading to make a profit because you need to have more skills to determine the price moves. But yes, I see that the profit that you can make on bitmex will be bigger if you can master or improve your skills.
