Anecdotal, but I have an uncle who, is a very good man but completely illiterate in terms of technology and closely resembles a "Larry the cable guy" stereotype, bought a surprising amount of bitcoin and then called me to ask how it worked, what make the price change, etc.

It seems shoe shiners can come in many forms. But that was the particular one for me to unload all of my bitcoin and other crypto and get out while I was ahead.
