The problems is that we don't have the relative tools.Like Visa.I have to waster another hale a month to get the card.But we have to spent these days.
the best way is to find a Chinese living in USA to help us. we pay him RMB and he gives us the ro zeny
you can also try paypal
and you can prety much add any bank account wether is chinese/korean wat so ever i think, i dunno hope it works. but yeh do not buy zeny of any1. the only best bet you can by buying zeny is buy wpe and resell them
