Enjoy a wide range of payment methods The wide range of payment methods offered by a casino is one of the main signs of security. If the online casino offers you different options, such as Visa and MasterCard credit or debit cards, bank transfers, Bitcoin or another crypto-currency, e-wallets like Neteller and Skrill or prepaid cards like PaySafeCard, then you are safe. However, never choose a vague payment method you have never heard of, as you may be cheated.
