I think it is still worth investment although the hype for it has been going down a lot recently. Still, crypto like Matic is hard to fail or stay forever at a low price since it was a smart contract, always a popular trend in the crypto market. Matic emphasis on the decentralized too so that's a good combo for the long run.
I wouldn't say Matic is bad, but you also need to look at some examples of cases that have existed and have also been around for a long time in crypto such as TRON and XLM where both also have smart contracts, but the price also does not experience significant changes and only increases when Bullrun market only, so I see Matic will also be almost the same as TRON and XLM, where Matic will continue to survive in the crypto space at prices that will not be so far from what you have seen at this time.
