I’m trying to identify a possible 2009/2010 Bitcoin-era mail-order source that may have been connected to
New Liberty Standard or a similar very early Bitcoin operation.
The lead appears to have come from a Dallas-area free print publication that discussed Bitcoin, the financial crisis, and how Bitcoin could be acquired by mail through a name and likely a P.O. Box.
The period I’m trying to narrow down is when Bitcoin was roughly in the $0.003–$0.006 range
I don't know about P.O. Box but about New Liberty Standard exchange and exchange rates, you can find information there
NewLibertyStandard account.
