I could see TAT selling shares OTC, then rebuying off the btctc passthrough and exporting them as direct shares, thus eventually draining the btctc passthrough of shares. Conspiracy?
it's just a service for people who want direct shares. Nothing more, nothing less.
+1. Also if TAT or anyone wants to buy up lots of shares on BTCTC, then he's welcome to do that. He'll only buy ~ 100-200 before he pushes the price up over 5BTC apiece.
