Bitcoin is a digital currency that's sent from user to user without the need for an intermediary. This crypto currency may not be regulated by an administrator, but it's a common payment method in casinos because it's easy to deposit and withdraw funds. Online casinos that accept bitcoins include 7 Spins, Bovada, Spartan, and Jumbabet.
Israel is known as the "only democracy in the Middle East", and is a strategic ally of the west. Gambling is strictly regulated and mostly illegal. Technically, online and mobile casinos are also prohibited, but in practice, playing in foreign casinos is possible, and players are not actively prosecuted. This makes mobile online gambling casinos relatively popular.
