That's simple. If you have 0.8 - 1 BTC balance in Dice, make
Payot: 49,
Bet: 10 Satoshi,
Increase On Loose: 10%,
Increase On Win: Return to base bet, On Auto Mode - in 10 - 15 minutes you will have
0.2 - 0.25 BTC profit, then stop game and withdraw all balance.

THIS IS NOT LONG RUN STRATEGY,
YOU WIN AND THEN WITHDRAW. AFTER 15 MINUTES YOU LOOSE IN ANY WAY !!!
THE STRATEGY IS JUST FOR SOME NICE WIN !!! I'll keep it simple: There are no safe strategies, not for the long run and not for the short run. Going all in at x1.25 payout will give you the same end result as with your strategy: you'll either win or you'll lose, but you'll for sure save yourself a crapload of time.
