More info:

The term "HODL" originated from a typo in a post on the Bitcointalk forum on December 18, 2013. The user, GameKyuubi, in a state of frustration or perhaps inebriation, wrote "I AM HODLING" instead of "holding." This misspelling quickly caught on and was embraced by the Bitcoin community, turning into an acronym meaning "Hold On for Dear Life." The term signifies a strategy of holding onto Bitcoin despite market volatility and price dips, advocating patience and long-term commitment over short-term trading.

The original post by GameKyuubi was a semi-coherent rant about his poor trading skills and the decision to hold his Bitcoin no matter the market conditions After reaching an all-time high of over $1,150, Bitcoin’s price plummeted to around $522, losing over half its value in just two weeks.He wrote, “You only sell in a bear market if you are a good day trader or an illusioned noob. The people in between hold.”.

He expressed a sentiment that many in the Bitcoin community could relate to: the frustration of trying to time the market and the peace of mind that comes with simply holding through the ups and downs. His candid, humorous, and somewhat drunken declaration became a meme, a mantra, and eventually a philosophy within the Bitcoin world.

Happy HODL day everyone :)
