This is a shit contest without any timeframe.a ref contest should have a ends time..you may set terms like only qualified referral are count who deposit and weager min 0.01 btc during the contest.no matter how much you give as a prize..but this looks a shit where you never know when this contest will finish.may be in 2017 some one managed to earn 5 btc as a ref commission,bull shit.
Well this isnt being paid for by the site its being paid for by me, an if the goal isnt reached by the said time then no one wins simple as that.
Which is why i haven't put a time on it as of yet.
