Your winnings with Bitcoin are not recorded anywhere, which means that you are completely anonymous when playing online. With Bitcoin you are able to deposit money almost instantly and sending money to others is a breeze once you have your first Bitcoin.
The drawbacks to Bitcoin is that the currency is open to high fluctuation and because there is no ties to a government or bank, you are personally responsible for making sure that your Bitcoin are safe. Buying your first Bitcoin is more challenging than paying through an e-Wallet system, though it has become far easier in recent years.
The bottom line
If you want to be able to withdraw your money quickly and a casino does offer Bitcoin payments, it is a great option if you care about the privacy of your winnings.
