And it's such a fascinating term! Holding is what Warren Buffett does, after having applied his unique evaluation skills before buying, hodling is what a True Believer does. "If you are not a True Believer and cash out early, you are not deserving of eventually entering the paradise of a bitcoin bet retirement."
And to people who self-identify with the term, I think it might also be a kind of rhetorical last line of defense for when someone criticises their trust and belief: "those may be fine arguments or not, see I don't care, I HODL which means I just don't take it as serious as you. Mind your own business and let me dream my dream". Could also be motivated as a psychological hedge for the day after, "sure, it was expensive, but look at fun we had!"
