I admit that what you are saying, is a possibility. Trying to hold it to buy more, but, I see CSTI lots of times as the second bid, for example, NITE is on the bid at .015, and CSTI too, but, in second place, and, this way he is not buying, just giving support to the stock.
I saw this lots of times, and, this goes against your theory. Also, he is almost all the time on the ask, and, in the first place. Sometimes when the ask drops, he stays above, so this behavior is confusing, you can't take a conclusion.
In my opinion, he is just making a market, and, making money, but, you can also be right.
