The only issue I see with this is that apparently every time there is a mil on the bid it is the same person buying.
The problem is how it applies to the company. If they are the only one buying then the support will crumble when they stop buying. The fact that the last bid of a million was at .0245 shows even the company's largest supporter is lowering his expectations since they wont support a PPS that is 10% lower.
IMO I think it is wise to buy SRSR every week. But at a mill a week a person with a large holding would be needing to declare themselves an insider in a very short time. So it would also be very wise to sell it every week too.
