BTC15 is the jackpot. Maybe that BTC150 is just for show off purposes (all cards BTC15 x 10).
The interface is good and I see efforts have been made to make the site very smooth. Clean, no ads, no shit etc. The no cost entry for first card is also interesting and really a good bait for gamblers to try their luck on the site. But anyhow, you must proved how fair your system is. Low chance to win at lottery so in return you must proved that your system is fair and you can pay the promised jackpot.
There are three results already, but where we can find the winners of each round? Was there no winners for the last three rounds?
Agree. Although anyone can fake the info, gamblers are not interested in stating their name location and birthdate. Email address is enough or bitcoin address with password.
About the winners, I think there is none as of the moment. It's hard to win on a guessing numbers lottery compare to other type of lotteries.
