I even did a POC of a smart contract back when ETH was <100$.
Ever since then I've seen very little practical applications and soo much bullshit - I would never "invest" into anything crypto related even if the payout was guaranteed - for the same reason I wouldn't go work for a betting company, hack people for money or run scams - that's not how I want to make money, and I do feel contempt for that entire "movement".
