someone moves the Satoshi's coins and dump everything on exchanges. Instant sub 10 probably before the coins arrives.
That would means either Satoshi goes nuts or someone hacked Satoshi coins
I do think this is a plausible scenario, sooner or later the Satoshi coins are going to play out. However, I actually don't think the price will stay low for very long at all. If the price drops to $10, then a million coins is only 10 million bucks and we know there are a ton of people that would scoop them and hold them for a long time at that price.
All Satoshi coins getting dumped would be a GREAT win IMO. I wish it would happen immediately.
