Why Tron, who needs it, and how this network’s rules differ from the rest — short and to the point.
Not abstract “crypto risks,” but the rules of this network. For each — what happens, and how Mitilena shows it before the Send button.

A USDT TRC-20 transfer needs energy. If TRX is not frozen, the network burns a few TRX from the address. Zero TRX — zero transfers, no matter how much USDT sits there. A transfer to an address that never held USDT costs roughly twice as much.

Tether can lock an address on Tron and does it more often than on other networks. USDT stays on the balance but will not move.

On Tron an account has configurable permissions: you can grant another key the right to sign transfers. That powers the “I’ll sell you an account with USDT” scam: the buyer sees the balance, the seller still controls it. Plus fake USDT under the same name.

Scammers send a tiny transfer from an address whose first and last characters match a counterparty’s. You copy “theirs” from history — and the money goes to the fake. On Tron this happens often.
Without frozen energy the network burns a few TRX — usually under a dollar; the amount depends on energy price and whether the recipient already held USDT. Mitilena shows it before you sign.
A block is 3 seconds; irreversibility is about a minute. Exchanges credit in one to several minutes.
Yes. Without energy a USDT transfer is paid by burning TRX. Keep a TRX buffer on the address for several transfers.
Cheap, fast, and accepted everywhere. That is also why there are more fakes and poisoned addresses here — the rules above help you avoid them.
