How the heck did you lose 12 Bitcoins on a regular dice game by using your strategy? I know that people on here like to exaggerate their numbers and all though 12 Bitcoin is a bunch of Bitcoin to lose on that gambling game.
You would have been better off by investing that money in an Altcoin like [Insert Altcoin promotion here] then made an earning and cashed the money out.

I hope that the next time you play Dice you will learn from this and manage the money that you have.
