Practical Example: If you bought 100 USDT of a certain currency with a fee of 0.1 USDT, this fee will be deducted from the voucher instead of being deducted from your balance.

Hello sir, if you could help me, I won a 30 USDT voucher and I need to use it for spot trading, but the amount is not available in spot trading or in funding. Should I wait for the voucher to be executed or is there a mistake?
