Who pays the network fee
Some operators cover it, others deduct it, and the chain matters more
A withdrawal fee deducted from your balance is a real cost, and it compounds if you cash out often. Some operators say they cover the network fee; others pass it through, and some charge a fixed per-coin fee on top. Each casino profile quotes the operator's own wording on withdrawal fees.
The chain matters more than the policy. An Ethereum withdrawal can cost dollars in gas at busy times; the same transfer on Solana costs a fraction of a cent. A fee-absorbing operator on an expensive chain can still be the worse deal.
