This drop almost had to happen too, given what I saw in the market earlier.  That was when the ask was .0042, but the bid was for 5.5 million shares at .0028.  Those two bids - same seller, I'm sure - disappeared at the same time, and after only a few minutes, when the a smaller bid appeared at .0035. 

None-the-less, if was clear there were few buyers in the market today, at least not are recent prices.  And, if there were sellers of larger blocks, they had to come down to re interest that buyer at 5.5 million shares. 

Someone appears to have done some decent buying after noting an virtual absence of buyers this morning - an abberation, I think, and not the start of a trend.

Anyway, it looks like the low for the day is past, and it's up from there.
