OP is trying to compare apples to oranges.
Alipay is a service.
BTC is a store of value/currency.
End of discussion.
Sorry, but there's more than just Alipay being compared here. Alipay is like clearcoin, but only because of the banking system provided in china.
They have no transaction fees and transactions are faster than bitcoin. As a consumer being paid in the local currency, bitcoin offers no real advantage for purchasing online (in fact it's worse in this situation..)
Also when dealing with LRUSDs, PPUSDs, DWOLLAs one can describe them as currencies.. so I don't see an issue with alipay being used in this manner.
