What does it mean to HODL?
Hodl is a slang term and Internet meme that is used in the Bitcoin community when referring to holding the cryptocurrency rather than selling it. It originated in a December 2013 post on the Bitcoin Forum message board by an apparently inebriated user who posted with a typo in the subject, "I AM HODLING. In 2017, Quartz listed it as one of the essential slang terms in Bitcoin culture, and described it as a stance, "to stay invested in bitcoin and not to capitulate in the face of plunging prices." TheStreet.com referred to it as the "favorite mantra" of Bitcoin holders.
Since entering the Bitcoin vernacular, HODL has become a backronym for "hold on for dear life".
