I cannot recall people making fun of new tech, mostly complaining about either ignorance, bad business ethics, risky behaviour or flaws that needs to be addressed. The current state of crypto businesses is quite horrible, too many sell "Get 10000% returns in 1y" crap to naive people. Will be interesting how the this crypto craze will look when looking back at it after it has cooled down.
