You must withdraw your initial deposit using the same method as your deposit. Then, you can withdraw the profit using any other method.
For example, I had deposit 100 USD through local bank transfer. After 3 months, my account have 250 USD. I must withdraw 100 USD through local bank transfer, then the rest 150 USD profit can withdraw through any other method such as USDT (of course before that I need to have USDT deposit record)
