Sometime last night most of chinese exchanges announced end of fiat deposit, rumors of which has been hovering around for half a month.
BTC and LTC are quite popular in China as they are mineable. Lots of people build monster-size mining farms. Pool operator even acquired small hydro power station to get access to low-cost power.
Not many Chinese hold ppc as you may see it from the ranking of China in the active nodes list. No. 10 I think.
We will see how it goes.
