Yeah that 1Feex account is sure a mystery. Whenever I look at a rich list, its always near the top. Hasn't been moved in over a decade and wonder if the private key is lost or not.
From what I remember, its when MtGox hacked (first time I think) and the CEO said it was sent to that address and it hasnt moved ever since. I remember that Craig Wright said he owns that address and then later on he said that he didnt own it.
Anyone have the back story on it?
For what I know, there were rumours that it was hacker address where he sent whole balance from MtGox, and surely he should have the pvk, but when stopped by police pvk may have been lost. Maybe there is somewhere the pvk, but withholded and will be used in, for example, ten years.
