Quit while you're ahead is bullshit

. You're always ahead, or you're losing. If it comes to staking or dicing, you can't be greedy enough. It doesn't mather if you lose your stuff in one day or spread out over a week. At least then you have a chance to win something that's worth it. If you want to quit before you've lost it all, you shouldn't have started. If you have a rediculous amount to lose, you shouldn't start either.
Good you made that money with graphics. That skill is something you can't lose
