🚨BINANCE NOW CHARGES YOU 6 USD FOR TRADING IN FUTURES....? 😨

Does anyone know why Binance is charging me so much?

I opened a position of 40 USD with x4 leverage at $FUN and left it for 8 hours, I made 2 dollars but they charged me about 6 dollars. That doesn’t make any sense... -.-

Do you know what it was due to?
