A good portfolio should be diversified, so I'm all for diversity. A portfolio containing 2 or 4 tokens is too risky, you might not be able to guess the trend or growth of that group of projects and be a so-called perpetual investor. People who find themselves in this situation find nothing better than to sell at a loss their unsuccessful acquisitions in an attempt to buy something else that might make a profit. They buy 2-3 projects into their portfolio again and thereby expose themselves to the same risk.

I have over 30 different altcoins in my portfolio, I advise you to create such a portfolio in the future. Its advantage is that you can always transfer liquidity from already profitable altcoins to other, more promising or new projects, and if an altcoin has not grown, you can wait it out instead of selling at a loss, because you have diversity in your portfolio and some altcoins will definitely grow, when others are still at a loss.
