With the advent of cryptocurrencies and the development of blockchain technologies, it became possible to create online casinos in which the results of games are impossible to juggle. Only casinos which use so called “provably fair” technology can guarantee a fair game. “Provably fair” means that any gambler can verify each bet and make sure that the casino doesn’t cheat. On top of that cryptocoins offer security, anonymity, global access and withdrawal at any time.
