The same dumb/average people who invested/traded in the mid/late 90's tech boom who thought they were market geniuses are the same types of people who did the same with the rise and (current) fall of Bitcoin and other crypto currencies. Human emotions and greed and euphoria are as old as time and as primal as food and sex. Adam and Eve and caricatures of everything else in between. Irrational Exuberance, as Alan Greenspan once called it in a different time. All the average Joes on youtube with their bitcoin mining rigs will lose their shirts as their little lakes dry up. Cryto Currency genius James Altucher said some currencies would go to a million in his ads. he was collectively pro-crypto across the board...hilarious judgement call. Idealism never wins in Wall St. -- Realism is just around the corner, and it will catch up real quick. always.
not true. bubbles last a lot longer than you expect. as the old saying goes markets can remain irrational a lot longer than you can stay solvent.
