I always hesitate when someone says that it has the method to easy earn bitcoin. We are all aware this is not easy and with gambling you always take the risk.
Gambling is opportunity to win some bitcoins but you can easily lose as well, don't forget that.
Agreed, I have tried some dice gambling and i think there is no way you can earn, win through playing those dice games. You will always lose at the end. Gambling is one of the biggest risk when it comes to earning bitcoins.
