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. 
It seems to me that all Dice sites are made for you to loose at some point. A few years ago someone taught me the strategy every time you win Subtract half of your bet. Every time you lose multiply your bet by 100%... The strategy seems to be ok for 10 to 15 minutes usually but after that I go on to lose 15 to 20 hands in a row. I am only usually betting 10 to 20 satoshis (Starting bet) When I do play dice but I could only imagine loosing 15-20 hands in a row starting with a minimum bet of .001BTC... I really only play dice when I get down to a couple thousand satoshi's when I am playing in a casino though. I really only use the strategy to get enough money to get one more Minumum Blackjack bet in though! It's not a game I play daily though. Blackjack is my favorite and the most provably fair of all the casino games. I also like to play a little roulette when I get up a little bit!
