ERC20 remains widely supported across wallets and exchange-style destinations.
Ethereum route
ERC20 USDT mixer routes trade higher gas for liquidity and compatibility.
ERC20 can be useful when Ethereum wallet support and liquidity depth matter, but a route estimate should make gas, service fee, delay and split overhead visible before conversion.
Cost reality
Ethereum gas changes the meaning of a low headline fee.
A 1% service quote is not the whole route. For ERC20, network conditions and confirmation timing can make the effective fee higher than expected, especially for smaller amounts or many outputs.
Gas can change quickly and should be separated from service percentage.
Buffer choice affects waiting time and route assumptions.
Ethereum remains analyzable even when timing and outputs are adjusted.
When does ERC20 fit?
When liquidity and compatibility matter more than the lowest network fee.
What should be priced?
Service rate, gas, outputs, timing and minimum route amount.
What is not promised?
Absolute anonymity, clean funds or legal protection.
