Why does the USDT fee on Tron change?

The on-chain figure is a USDT transfer to an address that already holds USDT (≈64,895 energy + 345 bandwidth); about double to a fresh address, read from trongrid chain parameters. It moves for two reasons: the network's fee market (gas, energy or priority price) rises and falls with demand, and the USD figure follows the TRX price ($0.33 when this page was built). We re-read both every 90 seconds and never fill a gap with an old number.

What is the minimum USDT withdrawal on TRC-20?

Right now: Binance 5 USDT, HTX 1 USDT and KuCoin 4 USDT. Below the minimum the exchange refuses the withdrawal; at or just above it the flat fee is a large share of what arrives ($1.50 of a 5 USDT withdrawal at Binance).

Which is cheaper for USDT, TRC20 or ERC20?

On-chain, right now: Tron (TRC-20) $2.28 against Ethereum (ERC-20) $0.457, so ERC20 is cheaper at the moment, which is unusual. The cheapest exchange withdrawal is $0.500 on TRC20 (HTX) and $0.300 on ERC20 (Binance). Both are Tether-issued USDT; they are not interchangeable, so match the network on both sides.

How to send USDT on Tron

Ask the receiver for a USDT address on Tron (TRC-20) and check the network name on their deposit page matches. USDT on another network is a different token and a deposit on the wrong one is usually lost.
On the exchange choose USDT, then network TRC-20; the form shows the fee and minimum. Right now the enabled rails are Binance ($1.50), HTX ($0.500) and KuCoin ($1.99).
Keep a little TRX on the sending address: USDT transfers on Tron are paid for in TRX, not USDT.
Paste the address into the address check to confirm it belongs to Tron before confirming; then use the route planner if you want every rail ranked for your amount.
