People don't take short positions against highly volatile assets like crypto because sometimes the market can remain irrational longer than you can remain solvent. The risk of a short position greatly outweighs the benefit even if you are right and if you use instruments that reduce the risk they are very timing sensitive. Was it always going to zero? Yes. Could I tell you when that was going to happen? Nope. Therefore no short opportunity other than going for a momentum trade. Most of the people saying "I told you so" have held the exact same line of reasoning on the way up, at the peak and on the way down. The only people that have decided things are different are the people selling crypto, i.e the people that bought and and yes, "We told them so".
