Great story Misha. Can you follow up with one on the economics of the payment alternatives for users and retailers please? In North America there is a lot of anger from retailers at the major credit card firms who charge from 1.5-4% of every transaction to retailers, and ban retailers who try to offer cash discounts.

If the economies of scale of Chinese providers can be used to earn trust of global users and benefit retailers they could move around the world quite quickly. Why would they care about these slower growing markets? It could diversify revenue and facilitate more trade with fewer intermediaries.
