> People knowingly buy into pump & dumps, gambling that they're on the early (pump) side and hoping to get out before the dump

I recently heard of a real estate person that wound up buying an entire neighborhood around one of the stadiums for next year's World Cup. The impetus for this decision was to jack up the rates during the tournament, and then sell them off after. Another person thinks renting a bunch of Teslas and then placing them Touro will be another get rich idea during the World Cup. There are all sorts of people that think they are smarter than everyone else and are so confident they just cannot think of any ways their idea will fail.
