The thing that interests me is that Satoshi, whoever they are, has millions sitting around in coin but is able to leave it untouched.
That tells me something: either they were already wealthy with a quite separate income stream which made cashing in not an issue or, Satoshi is some group of people or Governmental/other agency where it is likewise not an issue.
It's odd because Satoshi's White Paper and expressed views seem to be written by someone who is very interested in wealth creation from the standpoint of someone not already wealthy or a member of the elite.... which goes against those two points. Weird.
Or they're just afraid of taxes, government bodies or some gangs hurting them. Never will know
