That is very much obvious and is something I highly prefer given that I trade in Forex for years now, and I am not sure how you call leverage as a double-edge sword. If you are not capable of handling it then you are simply not capable to be a trader.
I will NEVER prefer exchanges much at all, as they dont bring the comfort you need not just in terms of the structure but also on several other points. So, I prefer
Crypto Broker only instead of exchanges and most people are slowly to understand that.
