For some reason I suspect the steady 1btc per 8 seconds buying bot might be connected to this. It might be how the trust maintains parity as investment comes in.
I can tell you with some confidence that the traders for Secondmarket's Bitcoin Investment Trust don't buy on the exchanges. That isn't to say they don't impact the price on the exchanges.
i thought that second market already holds the btc and sells them to the investors. the investors dont buy at exchanges, right.
It started with $2m dollars worth (18,000 btc at the time) but has to buy as people buy into the scheme. They mention links to around 100 sources, mainly large miners I guess which must be mopping up a lot of the new liquidity for now, 3600 btc per day at $300 = 1 million dollars new issuance per day.
