HODL is a common slang among Bitcoin holders that stems from an early forum post in 2013 where a user mistakenly wrote “I AM HODLING” in reference to his inability to time to markets and how just buying Bitcoin and holding it would be a better suited strategy. It has since become the mantra of a large portion of the Bitcoin community. Since then, acronyms have been made after the fact that refer to HODLing as “Holding On for Dear Life”.
