In the world of cryptocurrency, a lot of investors know this word: HODL. It started as a typo in a hastily typed post on bitcointalk, in which a fellow was telling everyone NOT to sell their bitcoin but hold on. Later it turned into a backronym, "hold on for dear life".
Now, whenever the market goes down, people bring on the old memes telling people not to panic, not to sell and above all, HODL. I'm here to tell you why that's really stupid.
