Which version of USDT does BitoPro support? Why is the USDT address invalid?

BitoPro currently support both ERC20-based (begin with a "0x") and Omni Layer address (begin with "1" or "3")

Note: 

The wallet address of USDT-ERC20 and USDT-Omni layer are not compatible with each other. Please make sure the wallet address of USDT before deposits and withdrawal, otherwise it might cause a transaction failure.
