I'd generally advise everyone to stay away both from margin tokens and margin trading, unless you really know what you are doing, like Windwisor.
If 95% new traders lose money, think how many lose money on margin.
With broker accounts the losing total oscillates in the 70-80% area (the stats are published for CFDs). I suppose with crypto's volatility and stop hunts this must be even higher without leverage. At 3x or 10x, I'm sure it's a great source of revenue for exchanges.
I got my whole margin account liquidated twice on Mex in early 2018 when I had little clue as to how to do it. Rich and Windwisor were trapped in risky leveraged trades without stops in mid 2019 and were panicking here in the group. Others lost most their funds and left for many weeks. It takes time to get profitable without leverage and when you do, you find out that you don't necessarily need margin most of the time anyway. That's where Bear's last posts on risk management come handy.
Never try to beat the market by increasing the risk, especially when losing. It's not some golden trick that no one knows about. It's how most of the market is punished most of the time.
