I personally prefer BitDice because of how simple and easy it is to play there. You won't face any issues withdrawing your winnings (no need for KYC as it should be with crypto casinos). You can also win a pretty big amount in a single bet. The maximum profit in a single bet is about 15 BTC for bitcoin. I personally feel like crypto casinos should accept some of the popular coins which have most demand (BTC, ETH, LTC etc.). BitDice also takes bets with their own token (CSNO).

There's an user who has won almost 30 BTC in the past week on BD...
