My guess is MMCap sold a bunch of those Call options, and is using all the shares they just picked up in the latest financing to keep walking down the price by selling into the bid, trying to get those options to expire worthless. Same thing happened last month, but at $3 versus $4 this month. Last month they weren't able to keep it under $3, too much buying pressure. Then the YouTube video released that weekend, MMCap stopped selling, and the stock exploded. 

I think tomorrow they are going to do everything they can to keep it under $4, but I have no idea if they'll be able to. But I think after Friday, with the selling pressure removed, we will have a sustained increase in share price again. It will be interesting to see if we get more promotion again before that. 

Regardless of the share price games, our future is so bright. And the more shares MMCap sells now, the less they have to sell us down in the future.
