HODL
Also called: hodling, diamond hands, hold on for dear life
HODL is crypto's term for holding through volatility, originating in a drunken 2013 forum typo for 'hold'. As a strategy it has worked well for Bitcoin across full cycles and disastrously for the many tokens that never recovered. It functions mostly as social reinforcement against panic selling — useful discipline attached to no analysis of what is being held.
