Just been speaking to the owner of the page in cryptobrains-cryptocurrency, hes just published It this morning as hes hoping to legitimise Bitcoin raffles with a simplified page and livestreamed draws, ive paid 50$ for tickets, as everyone says youll never know if you don't take risks
Looks like you got scammed by the site, site is fully coded on squarespace which is free web building platform
https://www.squarespace.com/This is not the way bitcoin based casino or raffle sites will start, they have their own custom platform built from scratch with payment gateway integrated.
If you really love raffles than you can play that on
https://yabtcl.com/ or
