A gas fee, or network fee, is the amount charged by the blockchain network — not the casino — for processing your transaction. The name comes from Ethereum, but the principle applies on every network: the fee is paid by the sender and its size depends on the network's current load, not on how much money is moving.
How large it is. The orders of magnitude differ many times over between networks. Tron and Litecoin transactions are typically the cheapest, Bitcoin and Ethereum noticeably more expensive and volatile at peak times. The same USDT moves on several networks: TRC-20 and ERC-20 are the same money, only the fee differs by an order of magnitude. The casino itself usually charges no handling fee; if more than the network fee disappears from a withdrawal, ask support for a written explanation and compare the amount in a block explorer.
How to reduce the fee:
- Choose a cheap network that the casino supports in both directions — a cheap deposit does not help if the withdrawal only runs on an expensive network.
- Do not split withdrawals into small amounts: every transaction is a separate fee, and one larger withdrawal is almost always cheaper.
- Avoid peak hours, when the network is congested and the fee rises.
- Check the withdrawal minimum. If the minimum is small and the network fee large, the fee eats a proportionally large share of the amount.
A fee set too low saves nothing — the transaction waits until the network accepts it and the confirmation is delayed. A comparison of networks, minimums and speeds is in the payments overview; which networks each operator supports is visible in the casino reviews.
How the network fee is made up
The network fee usually does not depend on your amount. On Ethereum it is the amount of work a transaction needs (gas units) times the price per unit; on Bitcoin the fee is set by the data size of the transaction, not by the amount transferred. That is why sending 20 USDT and 2,000 USDT on the same network costs roughly the same. The mechanism is described in Ethereum.org: gas and fees. The fee does not go to the casino or a service provider but to the network's validators or miners.
What the fee means for your withdrawal
The fee is a fixed cost, so its share is large for a small amount. Example: the fee is 1.50 USDT. On a 20 USDT withdrawal that is 7.5%, and you receive 18.50 USDT. On 200 USDT the same fee is 0.75%. Compare the fee with the size of your typical withdrawal, not on its own in euros. If the casino adds its own fee, add the two together.
Common mistakes
- Fee in the wrong coin. When you send a token, the fee is paid in the network's base coin (ETH, TRX), and it has to be in the wallet separately. See token.
- Reading the fee only after sending. Look at the amount before confirming and check the transaction afterwards in a block explorer. On Ethereum, gas is generally spent even if the transaction ends in an error, because the network still did the work. So check the address and network before sending.
- Comparing fees without the network. The same USDT costs orders of magnitude different amounts on different networks, so choose the network before looking at the number. Comparison: TRC-20 vs ERC-20 network fees.
