What securities are in your watchlist other than BTC and ETH and why?

I’m fairly new to crypto and the only tickers I could find of the crypto that I recognize are Bitcoin and Ethereum. I keep hearing stablecoins, which minic USD from what I understand, but I’m looking for others that have a higher purpose. I assume there are more out there of significance than these two or three. Thanks

I’m not necessarily looking for moonshots or hype coins, more like projects that actually solve something or have a clear use case beyond speculation. Even a general direction on how to think about evaluating them would be helpful.
