To withdraw funds in cryptocurrency, you must select an amount that’s equal or less than the net value of your cryptocurrency deposits.
For example, you deposit $50 worth of USDT and use it to trade. Your positions increase in value and you close the position for a balance of $75. You could then withdraw a maximum of $50 in USDT as that’s the net value of your deposits at the time. In this scenario, you have the option to withdraw the remainder in fiat by selecting a different payment method such as bank transfer.
