Among Bitcoin's earliest enthusiasts was Hal Finney, a console game developer and an early member of the "cypherpunk movement" who discovered Nakamoto's proposal for Bitcoin through the cryptocurrency mailing list.
In a blog post from 2013, Finney says he was fascinated by the idea of a decentralized online currency. When Nakamoto announced the software's release, Finney offered to mine the first coins — 10 original bitcoins from block 70, which Satoshi sent over as a test.
Of his interactions with Nakamoto, Finney says, "I thought I was dealing with a young man of Japanese ancestry who was very smart and sincere. I've had the good fortune to know many brilliant people over the course of my life, so I recognize the signs."
Finney has flatly denied any claims that he was the inventor of Bitcoin and has always maintained his involvement in the currency was only ever secondary.
In 2014, Finney died of the neuro-degenerative disease ALS. In one of his final posts on a Bitcoin forum, he said Satoshi Nakamoto's true identity still remained a mystery to him. Finney says he was proud of his legacy involving Bitcoin, and that his cache of bitcoins were stored in an offline wallet, left as part of an inheritance to his family.
"Hopefully, they'll be worth something to my heirs," he wrote.
As of today, one bitcoin is worth more than $10,000.
