this site scam dude
IMO its not a scam site. You can look at them like a lottery with a very very high house edge due to the change of hitting suck parlay. Its much more better to choose a random bookie and bet the same parlay there and you will end up with 2-3x more money in case of winning.
I think you are the one who don't understand how the site goes
Betting 0.001 btc /coupon prize there/ will bring you 200-300mBTC, in case of winning, in any random bookie in same selection parlay. You could do the match by yourself.
