I know Satoshi is claimed to possess 1.1 million BTC (which would be an insane amount)
But who are the other really large holders and how much do they own? Roger Ver? Gavin Andresen?
I remember someone claiming that Ver owns about 300.000 BTC, is there any place where this is confirmed?
I have checked
http://www.bitcoinrichlist.com but they only show adresses and we cant know with certainty which of those are connected.
Are there any confirmed large holders, who openly talk about the amount they possess?
There are just few who are talking openly about there bitcoin holds, I recall theymos opened a thread selling some of his personal coins "and changed his mind" and it was around 1000 BTC. Some members like dooglus seem to have quite a sum but not sure about the exact amount if they ever mention it clearly though.
