TRX
TRX sits in most wallets for one reason only. Tron makes you hold it, or stake it, or rent energy with it, before you can move the USDT you actually came for. It is a toll coin as much as an asset, which is why so many balances of it are exactly as small as they need to be.

The toll is paid out of the operation, so holding TRX is a choice rather than a requirement. Moving TRX itself works the same way as moving anything else here.
Questions
Do I need TRX to send USDT on Tron?
No. Energy is paid for inside the operation, which is what removes the rental step.
Should I stake TRX for energy?
Not for this wallet’s sake. Staking exists to make your own transfers cheaper elsewhere; here nothing asks you for energy.
What is energy, in one sentence?
Tron's way of charging for a transfer: you either burn TRX or freeze it to earn energy. Here you do neither: the cost is settled inside the operation.
