Bitmex was my main platform for margin trading for years but 4 months ago I was fed up with the overloads and decided to give Bybit a try. Haven't gone back since and moved all my margin funds over.
I think it's by far the best option these days so I wrote a review to give people some thoughts on the platform so they can make a decision about trying it out.
