People dont want buy so long digger still digging. He destroys the clam with use so long time.
Maybe that's the whole point. It could be someone who hates altcoins in general or CLAM in particular.
Though i think i know very little persons who would, without need, destroy value they own only because they dislike altcoins. I think it's more likely that he don't have a clue about trading. Though who could it be? Who owned so big wallets? Only exchanges i guess. Can it be a scam exchange that went down? And that is the reason he does not want to get exposed? Though when selling the clams his identity probably is know to the exchange.
