What is TRON energy? (and why USDT transfers burn TRX)
Every USDT TRC20 transfer consumes energy. If your wallet has none, it burns TRX instead — which gets pricey if you send often.
Energy vs bandwidth
Bandwidth covers simple TRX moves. Energy covers smart-contract calls — including USDT TRC20 transfers.
Renting/delegating energy to your address lets you send USDT without spending as much TRX.
When a pack pays for itself
If you pay Parcelo (or any TRC20 merchant) more than occasionally, a 65k–131k energy pack is usually cheaper than repeated TRX burns.
What we need from you
Only your public T-address. Never a private key or seed phrase.
