The only sort of mysterious thing left here is that transaction with the 240,000 shares just before the dividends stopped. Those shares had been locked, then they were unlocked, listed for sale, and purchased in a matter of minutes. So it's safe to assume it was some sort of insider action.
But...
Why?
If they knew it was a scam, and they were coming to the end of it...why bother moving share around at all, much less for money?
That part is still very puzzling to me.
offload shares knowing that bad PR will force the price down so you can buy back cheaper...
check the forums but say nothing.. watch the hysteria drop the price down further...
focus on getting more hashing power online so that you can feign legitimacy and suck more people into buying thus forcing the price back up.
realise that you are completely incompetent and that the forum users have discovered that you don't actually have your own chips and are preparing to hunt you down much quicker than you had anticipated....
cut and run...
end of labcoin story.
im still hoping they catch him and make him pay back the remaining money... its a long shot but hey..
