If you are a TRON user who transfer USDT everyday, you will find that there are two gas fees while transferring USDT. One is 13.3959 TRX，another is 27.2559 TRX.
Why there are two gas fee in TRON ?
It consumes Tron Energy and Bandwidth when we transfer USDT and it will burn TRX as gas fee if the Energy or Bandwidth is not enogh.
It burns 13.3959 TRX if we don't have 31,895 Tron Energy. And it burns 27.2559 TRX if we don't have 64,895 Tron Energy.
It consumes 31,895 or 64,895 TRON Energy which is depend on the USDT receiver's address has USDT or not. It consumes 31,895 Energy if the receiver has USDT. Otherwise consumes 64,895 Energy.
