HODL

“HODL” is a term used in the cryptocurrency community, which originated from a misspelling of the word “hold.” It was first seen in a post on a Bitcoin forum in 2013, where a user, amidst a crash in Bitcoin’s price, wrote “I AM HODLING,” in an attempt to say that they were keeping their Bitcoin despite the severe drop in value.

The term quickly became a meme within the cryptocurrency community, and now “HODL” is often said to stand for “Hold On for Dear Life.” It signifies an approach to cryptocurrency investment where one buys and holds onto a cryptocurrency long-term, regardless of market fluctuations, with the expectation that it will increase in value over time. It contrasts with more active trading strategies, such as attempting to buy low and sell high based on short-term price movements.

Seems like it originated from the thread below.
