What is Network Fee?

A network fee is the amount a blockchain charges to process a transaction. It is paid to the network itself, not to the casino, and it varies with congestion rather than with the size of the transfer. This is why "no fees" on a crypto cashier is true and incomplete. Somebody pays the network. If the casino pays, it usually sets a minimum withdrawal high enough to absorb it, which is why crypto minimums are often higher than the deposit minimums beside them. If you pay, a small withdrawal can lose a meaningful percentage to a fee that has nothing to do with the amount. The practical consequence is that coin choice matters more than casino choice here: the same €50 payout can cost cents on one chain and several euros on another, and stablecoins on low-fee networks are usually the cheapest route out.
