For every betting transaction (e.g. opening or matching a bet), you will pay a transaction fee (in Ether) for using the Ethereum network. The fee depends on the type of transaction and is usually worth a few USD cents. The betting app will provide all information and handle the payment process on your behalf.

The betting house you choose to play with might also charge a commission on your payouts. Due to the low cost of running a house on the Kryptium platform, you can expect the commission to be very low or even zero!
