Also makes sense, maybe these just moved to a new, safer tech for cold storage. In fact that is the most plausible explanation yet, why they moved like they did.
Yeah, If those are really old coins, they were in an unencrypted wallet... would make sense to move them to Armory or a paper wallet.
A bigshot miner from 2010 leaves 120k coins unencrypted for almost 3 years?
I guess anything's possible...
Anyway, it's pretty clear they weren't moved to an exchange. Either they weren't sold, or they were sold off the market.
Either way, I don't expect this to affect market prices.
Back in 2010 the best way to secure your coins was to transfer your wallet.dat to a (possibly encrypted) USB drive, delete and shred the original file from your computer, then bury the USB drive in the backyard.
I'm not saying that this is what's going on. I'm just saying 140K from 2010, I'd want to do something to make sure they're safe.
