I lost all my money into this site, remember when you invest in this site, you are just funding the next guys payout, somehow it always works out so that you can't get paid,
Don't invest in this site is my advice, donate it to somebody rich instead it's the same thing
It's a game, and if you are smart you will profit.
Do the math, compare payouts under 12 hours with the bankroll and if there is enough left over after paying them, "invest".
You might have been just unlucky.
