The min bet goes higher as the payout goes higher?
Surely some mistake!
The 1% pays out 325.68x and has a minimum bet of 8.00 BTC. So for every 800 BTC I send you, you're going to send me 2605.44 BTC back on average?
Sweet deal!
Also, do you really have the $700k needed to pay out if someone hits the 1% game with the max bet of 17 BTC?
Here's the RTP for each of the games. On the very slight chance that this isn't just a scam, play the 4% game - it has the highest RTP:
1% 325.68x 325.68% RTP
2% 192.88x 385.76% RTP
4% 97.86x 391.44% RTP
6% 41.67x 250.02% RTP
9% 26.59x 239.31% RTP
13% 16.69x 216.97% RTP
18% 7.25x 130.50% RTP
21% 5.47x 114.87% RTP
29% 4.73x 137.17% RTP
47% 3.34x 156.98% RTP
62% 2.18x 135.16% RTP
74% 1.44x 106.56% RTP
81% 1.12x 90.72% RTP
Edit: I don't understand the lottery aspect either. Only 4 of the 13 (what gambling site offers 13 bets?) pools is paid out each day, but it's not clear how they decide which ones. My guess is that nothing is paid out ever.
