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.
Switzerland is at the heart of Europe, at least in terms of geography. Famous for its political neutrality, it hosts several international organizations. Gambling in bricks-and-mortar casinos has long been a tradition in Switzerland, but online casinos are formally illegal. In practice, it is possible for the Swiss to play in international mobile and online gambling casinos.
