x100 leverage is very insane and unlawful. And you are proposing x200 leverage. So if BTC price moves 10$ then the user will be liquidated? I wonder if you will get a license to operate
with that such kind of risk factor that you will offer your customer. I believe that x25 must be the maximum and for me, It is too much.
I agree, but you are not forced to use that leverage, it is only an option by maximum, you can control your own leverage, either 25x, or 5x. your call.
