Bitcointalk is an Internet forum dedicated to the discussion of bitcoin, blockchain technology and cryptocurrency. The forum was initially created by Satoshi Nakamoto, the pseudonymous inventor of Bitcoin in November 2009.
The first user on the forum was named “admin”, and has an account registration date of November 17th, 2009. Satoshi Nakamoto created the Bitcointalk forum and posted the first public message in 2009 under the pseudonym “satoshi”, an account which was registered on November 19th, 2009.
Originally, the forum was hosted at “bitcoin.org”, a domain registered prior to the release of Bitcoin’s whitepaper.
The first bitcoin transaction took place at the forum, when software programmer Laszlo Hanyecz offered 10,000 bitcoins to purchase pizza, three days later a deal could be arranged to purchase two pizzas.
The commonly used cryptocurrency-trader meme “HODL” originated from a 2013 Bitcointalk forum post.
