In December 2017, unsolicited donations of over 100 bitcoins were sent to Antonopoulos by over a thousand followers of his work, after Roger Ver made a public post to Twitter on 5 December questioning Antonopoulos’s investment choices given his “eloquent” public speaking about bitcoin since 2012.

In March 2016, the first edition of Mastering Bitcoin was released by Antonopoulos, in print and online, followed by a second edition in June 2017.

In January 2014, Antonopoulos joined Blockchain.info as chief security officer. In September 2014 he left the CSO role.

In April 2014, Antonopoulos organised a fundraising campaign for Dorian Nakamoto, who was identified in a Newsweek article as the creator of bitcoin, Satoshi Nakamoto. The reporting techniques used in the article were controversial among journalists and Bitcoin community members. The fundraiser, intended to assist Nakamoto after the attention he received as a result of the article, raised 50 bitcoins, worth US$23,000 at the time.

On 8 October 2014, Antonopoulos spoke in front of the Banking, Trade and Commerce committee of the Senate of Canada to address the senators’ questions on how to regulate bitcoin in Canada.

In 2012 Antonopoulos became enamored with bitcoin. He eventually abandoned his job as a freelance consultant and started speaking at conferences about bitcoin, consulting for startups, and writing articles free of charge.

Andreas M. Antonopoulos (born 1972 in London) is a Greek-British bitcoin advocate, tech entrepreneur, and author. He is a host on the Let’s Talk Bitcoin podcast and a teaching fellow for the M.Sc. Digital Currencies at the University of Nicosia.
