Altcoins are very volatile so if you are short trading you will always get this opportunity but for this you need to know technical analysis or take help of someone who knows very good analysis. But if you want to hold long-term, you need to find some potential coins in which you can invest and hold for a long time. Altcoins will soon see a bull run as Bitcoin's bull run is almost over.  And after that Alt season will start. So if you invest now you don't have to wait too long.  But there are a lot of risks here so monitor it carefully. You can see SOL , JUP , ETH , TON , NEAR , BNB .
