This is very interesting question, unfortunately without reliable answer. Satoshi is for sure one very rich person, no doubt, but my question is what is his intention with so many coins in his pocket? Influencing market prices is only one option. What do you think guys?
Why do you care? Are you scared he might sometime dump his holdings?
This greed some people have is so annoying. Like, if he is holding his coins (or forgot them) and will never use them again, consider them a donation for everyone
as he said himself. If he ever dumps them all, consider it another positive aspect as more than probably a million BTC would be redistributed. Any way you take it, it's a positive thing imo. But why do people hope so much that he doesn't have a single coin anymore? Do you deserve yours more than he deserves his?
