yea it's a legit site and everyone that joins knows how it works so it's nothing shady back in the day during it's prime it was one of the most popular sites in this category. (2) $1 payments and you were in no need for further investment so it was a good while it lasted but the problem was it started getting labled as you called it ponzi scheme pyramid scheme etc etc (not this site specifically but the category of payment randomizers) so all the payment processors blacklisted this type of site. it was paypal at first then it was converted to e-gold then to manual only so it just kinda died.
But with the right person i'm sure it could thrive without the fear of being blacklisted with btc so if anyone is interested please step forward.
