Bank transfer is one of the most convenient and secure banking methods that allow you to transfer money from one account holder to another, anywhere in the world. You can then use it to directly transfer money from your bank account to the casino of your choice to start playing real money games. Other than the fact that banks have an added layer of security when it comes to transactions, online bank transfer has been around long enough to gain trust and credibility, making it one of the most used banking methods.
