Bagholder

A "bagholder" is an investor who is left holding onto a cryptocurrency (or any security) that has dramatically decreased in value, often to the point of being nearly worthless, with little to no hope of recovery. This term implies that the investor is stuck with "bags" of unsellable or heavily devalued assets, having missed the opportunity to exit while the asset still had significant value. It's a particularly painful position as it often results from a combination of poor investment decisions, emotional attachment, or being on the losing end of a "pump and dump" scheme.
