Image by for3w via FlickrKaiser Kuo at the Digital Watch of Ogilvy gives an overview of Tencent's monetary policies, not to manipulate China's currency, the Renminbi, as the Central Bank last year feared. Its Q-bi, used at its popular service QQ but also elsewhere, seems a good tool to play around with its quarterly results and its shares at the Hong Kong stock exchange.

As promised, this time around the meat of the story centers on allegations that Tencent is manipulating its virtual currency so as to impact not the RMB, but rather its stock price

Kaiser Kuo thinks it might all be not very illegal:

Practices like this, which I suspect are commonplace, aren’t particularly nice though they hardly seem criminal and aren’t even plainly unethical. A more cynical observer might suggest that anyone foolish enough to dump good money into a few lines of code in they’ve somehow invested with a soul, with needs, with personality — well, you know what they say about a fool and his gold.
