Nowadays people are bullish on polygon and doge, maybe you can try to research both altcoins then you can give your personal opinion when it suits your criteria then you can use your money to invest there but keep in mind that cryptocurrency is still on a bearish trend. Personally, when I'm looking for a new altcoin to invest I'm just looking at their whitepaper and their product if it is worth it to invest then I'm going to give it a try.
