The lesson here is some are more riskier than others but also come with a higher expected reward. I think it's good strategy to spread the portfolio a bit. For example, $5 investment into a memecoin could give 500x and if goes to zero, it was still just $5.
Investing in blue chips at the same time can easily get you that $5 back.
Yeah, diversification is a key factor in crypto investment which we need to focus more on it
