To invent the most disrupting technology of 21st the century (so far) and to hide himself in a cage is an act of utmost introversion.
At one point in this interview, he actually says, "When I created Bitcoin.." and then immediately corrects himself. If it was an actual slip or if he did mean to say Bit Gold is uncertain. The interview could have been very interesting, but sadly he was constantly interrupted. Still worth a listen, though.
He always becomes a mystery, although there are any person said as Satoshi the claim is doubted, when he is still alive, maybe will never show the face, if hold so many Bitcoin, maybe just to sell when needed.
I wonder if he is a wrestling fan. It would certainly make a good stage name. Reminds me of this guy from my youth. https://en.wikipedia.org/wiki/Kendo_Nagasaki
https://craigwright.net/blog/bitcoin-blockchain-tech/how-bitcoin-won-the-race/ I think you are going to be right.
I think the more important question is: Are those never used 1MM BTCs accessible and can they be a systematic risk to the crypto ecosystem if released all at once?
