Yes, I had been betting  lottery ever since and unfortunately I was not able to experience any winnings. On the other hand, if you are referring to online lottery, I haven't tried to bet on it yet. However, if you really wanted to earn profit I think it would be better for you to participate bounty campaigns where at least there is a chance that an individual could be able to earn from his/her participation. Also, the token reward also depends on the rank of the member wherein the higher rank the better reward.
