The transfer fee and the amount received are different numbers

A matching address format is not enough

Some networks use similar-looking addresses. Even an address that is valid on the selected blockchain can belong to a service that does not credit that asset on that chain. Match both the coin and network, not only the pasted characters.

USDT on Ethereum, TRON and TON follows separate transfer routes. A withdrawal labelled with one network does not become a different route because you paste another address. Check any required memo, tag or comment too; a receiver may use it to assign funds to an account.

TON is the blockchain name. Its native currency was renamed from Toncoin to GRAM in 2026; USDT on TON remains a separate token. A service may still show an older asset label. Follow its actual supported deposit instruction and ask the recipient about an unclear label before sending, rather than guessing from the name.

Ethereum gas is payment for work, not a percentage of USDT

Ethereum's transaction cost is gas used multiplied by the effective price per gas unit. One gwei is 0.000000001 ETH. The cost depends on the operation's work and the network's fee conditions; similar token transfers can cost similar amounts even when they move different sums.

For a calculation example, suppose an operation uses 50,000 gas at an effective 20 gwei per unit. The cost is 1,000,000 gwei, or 0.001 ETH. These inputs are hypothetical. They are not an estimate for your USDT transfer, and a wallet's gas limit is not the same thing as the gas eventually used.

A failed operation that is executed on-chain can still consume paid gas. An error before broadcast is a different event. Read the transaction result before retrying; repeated attempts can incur repeated costs.

TRON resources and wallet fee features change the preview

TRON uses bandwidth for transaction size and energy for smart-contract work such as a USDT transfer. If the sender lacks the necessary resources, TRX can be burned to cover the operation. The requirement can vary with the operation and account state, so a quoted TRC20 withdrawal fee is not a fixed law of the chain.

Some wallets handle costs through a paid feature. Keeper can use Battery for supported TON and TRON transfers, and its USDT-on-TRON support also offers other fee options. A send without buying the usual fee coin still has a cost; inspect the charge actually shown before confirmation.

An exchange withdrawal can deduct a set USDT charge while the exchange handles the network transaction. The sender's quote determines your debit and recipient amount. The fee shown in a blockchain explorer does not necessarily equal what the provider charged you.

Bitcoin fees depend on transaction size

Bitcoin fee rates are commonly expressed in satoshis per virtual byte. The number of inputs and outputs affects transaction size; network demand affects the rate needed for a chosen confirmation target. Two payments of different BTC amounts can have similar fees if their transaction sizes are similar.

Read the wallet's rate and total fee estimate together. A lower rate can mean a longer wait, and a casino may wait for its required confirmations before crediting. An exchange sets its own BTC withdrawal charge, which can differ from the transaction's network cost.

Add every transfer leg and provider charge

Buying on an exchange, withdrawing to your own wallet and sending onward can create a purchase cost and two separate transfer costs. Add conversion spreads, provider fees, network fees and any fee-token purchase you actually need. Do not add a second transfer purely because it looks like a way around a service's prohibited-use terms.

Altyn advertises a 1.5% stablecoin broker charge plus a selected network fee. That is a service charge, not Ethereum gas or a universal TRON tariff; its user-owned-wallet transfer conditions also apply.

Antarctic's FAQ lists inbound top-up charges of $2.75 for USDT on TRC20, 0.2 TON for its TON route and $0 for USDT on TON. Those are the FAQ's labels and inbound charges, not a promise of a zero-cost onward transfer. The service's terms prohibit gambling activities, so these figures should not be used to choose a casino funding route.
