Apparently martingales don't work?? They are fun though
It works if you've got a lot more or an unlimited amount of money, but not if you're just going to make 5 bets. Double it and you'll last a lot longer, but keep going and you'll lose it all eventually. If it was a foolproof system no casino would have any money.
The other part of the problem is that you can't increase your bets indefinitely even if you have an unlimited amount of money. Every casino out there (and PrimeDice is no exception) has an upper limit on bets which effectively puts an end to doubling bets. Also, martingale becomes exceptionally tiresome if you start at the lowest possible bet (i.e. one satoshi in our case)...
