Investment analyst Matthew Sigel claims Jack Dorsey is Satoshi Nakamoto, citing his deep cryptography expertise, early Bitcoin advocacy, and a bizarre timeline: Bitcoin’s first transaction happened on Dorsey’s mom’s birthday, and Satoshi’s last mined block was on his dad’s. A 2014 email hack even linked Nakamoto to St. Louis—Dorsey’s hometown. Dorsey denies it, but the mystery grows.
