Not quite true, as I see here this site give us a lot of benefits, like reward points,the higher your wagered then you can get a lot of reward points. Your money does not really gone here but somehow it converted your loss into point which can be redeemed. I think they have quite good thought, although the house edge is above the average site but they have something that they offer so this site is pretty well developed
This site is fully rigged and manipulated, you can see that in faucet they are giving only 100+ bits and the lottery system is totally manipulated by the site owners as most of time i have seen that top 4 winners are always from new accounts and their are accounts who are winning on low lottery tickets. Even not a single real users have claimed that they won the lottery on this site.
100 bits? Are you sure that they are giving 10k satoshi on the faucet? 10k satoshi is a big amount from a faucet in case you get it on each claim. Regarding the lottery, indeed it is not provably fair but we cant prove that it is manipulated by the owner.
