Looks like a low volume walkdown to me. Someone is accumulating. Where do you see "huge dumps"?
It went down the whole ride from 0.00000078 to 0.00000010 and rightn now buy orders are on 0.00000050, less than half the value it's been having lately. That's what I'd call "huge dumps" too!
A huge dump indicates huge volume. There is very little volume with this price movement. Someone is trying to shake coins loose for accumulation. If volume was larger than normal then yeah it'd be a dump but with this volume it is clearly not.
