HODL

HODL is a key term on the growing list of cryptocurrency related slang. It originated in 2013 when a tipsy forum member made a thread entitled ‘I AM HODLING’ (a misspelling of ‘holding’) to declare his decision to hold Bitcoin no matter what. Other forum members immediately latched onto the term. HODL has stuck around and is now used as an acronym for ‘Hold On for Dear Life.’

HODL is more than a slang term though – it has become a philosophy centred on the belief that cryptocurrencies are the future and shouldn’t be sold during market dips. There are literally hundreds of stories out there of people who brought Bitcoin early on and sold it when the price reached a few dollars, not imagining it could get any higher. These stories, along with those of early adopters who have since become millionaires, add fuel to the philosophy of HODLING despite FUD (fear, uncertainty and doubt.)
