Crypto gambling is no different to playing/betting on a fiat casino site except you use crypto currencies to deposit and wager. As an example a player uses BTC or ETH to deposit and wager as a pose to USD/EUR. Its worth noting that some Cyrpto gaming sites do also allow deposits and withdrawals to be made in fiat e.g. USD/Euros. As a player you get the best of both worlds! Typically we have seen that when you use crypto on gambling sites, bonuses and rewards tend to be more generous, something all players love!
