Every developer certainly wants their projects to grow rapidly each year, but it's important to remember that competition in this industry is incredibly complex. It's difficult to determine which altcoins will lead the way in the future, aside from Sol, BnB, ETH, and others. To date, many altcoins have failed to demonstrate significant technological progress, often trapped by hype without a solid foundation. However, some altcoins show potential for growth, particularly those focused on scalability, security, and other aspects. I think don't speculate too much when choosing an altcoin, choose one that has been around for a long time, this is much better. Appreciate the energy (money) that you earn, don't make the wrong choice in determining the assets you invest in.
Everything you've said above is quite fundamental, and I happen to follow their price developments. But, if someone wants to invest, it's best to hold only two or three, and at most five. It's easy to control, even if the desire arises to temporarily trade, holding any holdings at any time.
Market conditions often change, and trading doesn't always guarantee or provide greater profits. Instead, it can disrupt concentration, making us become dreamers who always hope for a miracle to come, or in common parlance, "If they pump goes blah blah, then I'll be rich overnight."
