9 years ago. Satoshi Nakamoto posted for the last time on the Bitcoin forum, announcing version 0.3.19 with new limits against denial-of-service attacks (attempts to overload nodes).

The "HODL" post, 2013
6 years ago. A bitcointalk user called GameKyuubi posted "I AM HODLING" during a sharp price fall, misspelling "holding". "HODL" became slang for keeping bitcoin rather than selling it.
