An account once associated with Bitcoin ($BTC) creator Satoshi Nakamoto posted a cryptic message on P2P Foundation, a platform dedicated to advocacy and research of peer-to-peer solutions. The account is tied to Nakamoto's old email address, satoshin@gmx.com, but this email address was compromised in 2014, so it is doubtful the person(s) behind the new post is the real Satoshi Nakamoto.
