The term "HODL" is often attributed to a typo of the word "hold" and was popularized within the cryptocurrency community. It originated from a 2013 post on the Bitcointalk forum when a writer decided to hold onto their Bitcoin despite a 39% price drop. "HODL" refers to the "buy and hold" strategy, which may not be suitable for everyone, especially during bear markets when prices can drop significantly. Ultimately, the decision to HODL or sell with the intention to buy back in is a personal one.
