The cryptocurrency and blockchain communities got into the Halloween spirit this week – and as shown on social media, more than a few people went out in style.
Last year saw costume takes such as "Bitcoin Bubble Boy" and a real-life private key, and that kind of imaginative spirit was on full display for 2018.
This year's Halloween also marked the 10-year anniversary of the release of the bitcoin white paper. In 2008, the pseudonymous creator of bitcoin, Satoshi Nakamoto, first circulated the paper among a list of influential cryptographers – thus setting the stage for the cryptocurrency's formal launch the following January.
