Your observation is equally pointless. You're the one using it as an argument though.

My observation is not pointless, it is literally the point of the argument, namely that crypto projects blast out tons of hype but never pan out into anything useful. Your rebuttal was "well, other things that people said were overhyped turned out to be paradigm shifts", but what I'm telling you is that your rebuttal does not tell us anything meaningful because it is equally true of all the failures as well.
