Your source lacks somewhat in professionalism. My two favorite quotes:

"According to Tencent, there are two Chinese mining teams capable of processing large amounts of Bitcoin transactions. One team, dubbed friedcat, boasts the largest mined amount of Bitcoin worldwide..."

"However, many are less optimistic about the future of the currency, questioning its stainability and constant fluctuations."

That's always bugged me: bitcoins are great, but how can I stain them please?

Anyway, ASICMINER shares are so esoteric its hard to believe an interest in Bitcoin has led to an increase in ASICMINER price without a corresponding increase in bitcoin price.
