As we explained previously, when you want to buy cryptocurrencies, a good solution is to create an account on an exchange like Binance.com or WOO.org. When you send money from your bank account to an exchange, the reverse operation also works. That means if you have won bitcoins at an online casino and you withdraw them from the casino to send them to your account on an exchange, you just need to sell your bitcoins for euros and then request a withdrawal to your bank account.
