It has often been reported that the creator of bitcoin - Satoshi Nakamoto- has at least a million bitcoins, that could spark a lot of market distortions should those coins ever move from their wallets, but recent report by Bitmex's research team suggest figures 30 percent lower. 600 - 700k bitcoins What do you think? Any significant difference? Reference: https://news.bitcoin.com/satoshis-1-million-bitcoin-haul-could-be-smaller-than-first-thought/
I can't reached the your reference link. This research is not correct i think, Satoshi Nakamoto own several million bitcoins. 600-700K is small amount as a developers. Many unknown persons owned million of Bitcoins it's published by journal.
