Like I've always said, for your good and sanity, avoid trading the futures of $MYX for now. It was designed to rip you off through funding rate and all. Avoid it at all cost for your sanity. Why would you be paying a huge amount for perpetual every hour... Profitability was always going to be difficult with such terms.
I took some short trades on it recently too but won't advice you to do it. They were taking almost 10 percent of my position every one hour. They're clearly sick... It looks like similar scheme is being cooked for the newly confusing launch of $0G
