P2P exchange probably is not that popular because traders prefer exchange. We have OpenTrade here for that. However, China restrict crypto exchange so that P2P in Yuan RMB vs Bitcoin or Marycoin would be very useful if it works.
I know Bisq P2P exchange allows Alipay (支付宝) now, their next release will support Wetchat pay (微信支付)。 These two are most popular e-payment system in China
and actually the chargeback situation on these two are a lot better than Paypal or credit card.
Would MarycoinExchanger (p2P) platform allow that P2P trade to go through on either Alipay or Wetchat pay for those in China?
