How do casinos catch card counters?

I often play bitcoin casino sites. But recently, friends told me about a site where there is not only replenishment with cryptocurrencies, but also staking it is a bitcoin casino sites where you will find many useful features, for example, they have BFG is the utility token of the BetFury platform launched on the BNB Chain and certified by CertiK. BFG’s unique mining solution, by playing games, and Staking opportunities became a hallmark of the BetFury project. User needs to make bets on BetFury and BFG tokens will be automatically added to the game balance. The more bets you place – the bigger amount of BFG you mine. I recommend it, because I have been using the service for a long time.
