There's something I don't understand...
Is it actually possible to track and estimate the size of some other individual wallet? I've seen the posts referencing users who have/had tens of thousands of BTC but, without any way to track their transactions it's entirely possible that they take profit daily and those coins have since been redistributed.
The amount of coin being traded would suggest that a lot of it is being held but, how can someone say whether that hoarding is confined to a few individuals?
you could probably wade through the blockchain to discover that the list of "top 100", referenced above, likely included multiple wallets held by single individuals. i don't know - and there's no way to tell for sure - but i would suspect so.
i also don't care. more power to them.
and i am quite content to think that i'll be able to afford a small sailboat which will run rings around vladimir's mega-yacht. we'll all have a party on the costa del sol, one of these days...
