You can extend that take to almost all of DeFi yield farming as well. APYs almost always rely either on a greater fool buying the useless governance tokens (which almost always trend down in price), or on late-comers paying entrance/exit taxes to early entrants. That's without even going into the tokens whose central mechanics are merely about disguising Ponzi schemes (Fei, Safemoon, Hex, to name only the billion dollar+ ones).
I'm also a die-hard crypto fan, but having to constantly look out for Ponzis around every corner is tiring.
