In april 2016 this illegal substances market went offline with no trace. Nobody has ever learned the identity of the owners or what happened to them.
I think it’s pretty safe to say whatever happened to them, they have lost access to this wallet. The usual practice back then when a market was exit scamming was to move all the coins to new wallets, which they never did.
It was a pretty large sum of money back then, but now obviously it’s worth over a quarter billion dollars.
Is anyone keeping track of all the lost bitcoins in the wild? How many do you think there is?
