can someone explain to me how to use this #Cupondedescuento ? I already deactivated the commission discount of #bnb , I already tried to make purchases sales in #Spot , I don't know what else to do, it's already active, but it doesn't seem to be used because I'm still being charged #comisiones , can someone explain to me before the coupon time runs out, and if I am buying with commissions from #USDT , it should work.
