Rake in the lottery is insane now. 1.59 given away for the 10 winners with over 4BTC worth of tickets bought.
Actually, not all of these tickets were really bought. Mostly of these tickets comes from Multiply btc game after user wager required amount of btc, also from free faucet claims, and tickets received as referral commission. Only part of all these tickets were bought with BTC.
Correct, the are still paid by revenue from the dice game. Go back and see older drawing paying 88-90% of total tickets bought. It has changed drastically with the last btc spike.
