Have anyone profited out of dice in the short or long term. I have been trying the best and lost all, I can't leave it. Once after I loss I have gone beyond my ability. Finally as the wallet got emptied, I bought bitcoin particularly for betting and lost even the amount earned from my day job. I used to experience win, but at the end it is a loss. I miss the right time to stop and leave. 
Some of my friends also attempted to earn in dice sites. When they discover a technique how to win with a minimal loss they try it for some days and they even don't last a week getting profit from it. If you win then you're lucky at that time but don't think it will happen often. Gambling is a game of luck. Stop thinking you'll earn in dice sites or it will cause you harm in the long run not just yourself but also to people around you.
