QQ coins are still very much alive and well - it is simply that they can't be exchanged for RMB but instead only for the purchase of goods and/or services (basically this was to stop one company from effectively being able to create inflation by arbitrarily printing its own "money" which if course is not really the same situation with Bitcoins).
Also what is *legal* is not the same as what is *enforced* and in fact what is *common practice*.
Virtual currency may only be used to buy online game items, the Ministry of Culture said in today’s statement. Game operators must provide the ministry with information about their virtual currencies, according to the statement.
So only Tencent QQ goods and services could be purchased with Q-Coin.
