so lets try and game theory this a bit more as to why this buying is occurring.
options:
1. chinese are buying btc's so they can move their yuan out of china into a different fiat currency.
Yep, I believe there are controls in China/HK where you can only move $5,000 per day out of the country without a bunch of paperwork and business invoices. India is the same, btcindia.com would also be a major exchange should it ever be created
