HODL is a term derived from a misspelling of the word “hold”. It originated in 2013, with a post on the bitcointalk forums by a user called “GameKyuubi”, aptly titled “I AM HODLING”. It was a drunk, semi-coherent, typo-filled rant about his poor trading skills and determination to simply hold his bitcoin from that point on.
Since then, this misspelled term became very popular and widely used in the cryptocurrency world. Whenever a person says in a conversation that he/she is hodling or suggests to hodl, it means that they believe their coin will be profitable one day, if not today.
