Cryptocurrency in online casinos is used to play games with it, as well as for fiat money. I think this is interesting, this is exactly what most licensed cryptocurrency casinos do, and it is licensed, and therefore honest. If you play in such casinos, then you and your money are safe. For example, when I play at the https://jennycasino.com/casino-category/bitcoin-casinos/ casino and win, I know for sure that the winnings will be withdrawn to my card, and at the appointed time, and this means that you can play games safely at Bitcoin casinos.
