A sustainable profit + safety is better than high profit rate with risk.
If one day, you increase only 5% of your balance, after 365 days, you can get:
1.05^365 = 54,211,841 x your initial balance

Or couse this is too much dreamy. However, try the above scrypt with a dicebot supporting Lua language, you may have a very exciting time of playing.
If you play dice often enough even at the lowest possible starting bet of 1 satoshi and on a bankroll of 1 BTC you will probably see that eventually you will bust. It seems impossible at 1 BTC because it is roughly 1 in a billion bets to hit the losing streak (much less because of doubling and of house edge) but variance is variance:)
