If this someone does indeed have quite a few shares they can sell low, which might scare some people who bought at .0003 or .0004 to sell too taking their profits and leaving. If they can scare enough people into selling they will have an opportunity to buy more cheap. JMO.
Also I am not saying this is what's happening it is only my opinion. Could simply be impatient people who took their profit from .0002 or .0003 or something, and want to move on. If so, like you said they will be missing out on some serious green. IMO.
