I'm interested in casinos that allow me to deposit and withdraw using cryptocurrency (such as BTC) without converting it to fiat currency. In other words, I want to be able to keep my entire bankroll in BTC (or other supported cryptocurrencies) while using the casino.
There are just too many crypto casinos that you can try if the main idea is just about keeping your balance as what you deposit. I'll start with Stake, Primedice, Fortunejack, Coinroyale, Chips.gg, Bitsler, Crypto.games, Betcoin, BC.game, betfury, jacksclub, vipgame, and many others. Basically the number of casinos that convert user's deposit into fiat currency is not much compared to those casinos that keep the balance as what is deposited by users.
