Crypto network fee
A crypto network fee is the charge paid to a blockchain’s validators or miners to record a transaction, and it goes to the network rather than to the casino or the wallet app. You meet it whenever you deposit or withdraw in coins such as Bitcoin or Ether. It is set by demand for block space, so the same transfer can cost a few cent one hour and noticeably more the next.

How the network fee is calculated
Bitcoin prices the fee by size, not by amount: virtual size in vbytes × fee rate in sat/vB. A simple one-input, two-output transfer is about 141 vB, so at 10 sat/vB it costs roughly 1,410 satoshis whether you move €20 or €20,000.
Ethereum uses gas instead. The fee is gas used × (base fee + priority fee), and a plain ETH transfer uses 21,000 gas. The protocol sets the base fee from how full the previous block was, moving it by up to 12.5% per block, and burns it; the priority fee is a tip to the validator.
Your wallet estimates both parts for you.
Network fee versus casino withdrawal fee
Players often lump the network fee in with the operator’s own cashier charge, but they are separate costs set by different parties.
Network fee | Casino withdrawal fee |
|---|---|
| Paid to validators or miners | Kept by the operator |
| Moves with network congestion | Fixed or percentage, per published terms |
| Bitcoin ignores the amount sent | Often scales with the amount |
| Can be lowered by waiting | Set regardless of timing |
| Shown by the wallet before sending | Varies by operator; check the cashier terms |
| Unavoidable on every on-chain transfer | Many operators charge none |
Where Irish players meet the fee
On a deposit, you pay the network fee from your own wallet, so the casino credits the amount that arrives. On a withdrawal, practice varies between operators: some absorb the fee, some deduct it from your payout, and some fold it into a flat crypto withdrawal charge without itemising it.
What I check first is whether the cashier names the network.
Sending USDT on Ethereum and on a cheaper chain can cost very different amounts, and picking the wrong network can lose the funds entirely, which is a far worse outcome than any fee.
