Yeah totally fair point - bought those cards half because I'm an nba fan, half because I thought they'd pump - I def don't think this makes me a good investor I just got lucky. I put in less than 10% of my net worth in for fun - it just ended up growing. Verify here if you don't believe me: https://evaluate.market/accountValuation?externalUserName=aa...
As for the rest of the portfolio, don't emulate it! Do what works for you, that's what the section below is for - I'm just being transparent. Most definitely consider more credible people, I just hope my suggestions might save people from the devil that is inflation.
