I dunno if I should trust this

because some are saying it's a scam and some are saying it's good... might put $5 when I get the
BTC0.005 from gifthulk.com ...
Read carefully. Nobody, who tried the system, say this is scam. Only guys, who even did not register, said bad words about x-value. I think, they are webmasters with their own projects. And they just made black PR.
I did not see any person, who did not receive his payment.
Thus, x-value always pays.
