I see there are some one refer new payment processor here and there, it is c-gold, I am not sure if there is any one use it now,but I didn't find any site accept it as payment processor. do you think this kind of payment processor like e-gold will be popular ?

I have had a c-gold account for quite a while. I think it is reliable, easy to cash in and cash out (i do this at e-forexgold.com) and secure.
