There is simply a lot of demand for MATIC right now because of the DeFi applications, they are pretty much only useable to retail investors through the Polygon network because of the gas situation on ETH.
But it also depends on ETH2.0, and how much that is able to scale ETH and facilitate cheap transactions. If successful, MATIC's use case would be greatly diminished.
It's possible MATIC will gain a lot of users into its platform during the course of the year because of its attractive fee rates and transaction speeds. But I don't think it will outperform Ethereum, simply because it's a sidechain (not an altcoin). In other words, Polygon (MATIC) relies on the main ETH blockchain to survive. Without it, Polygon would be doomed. The market is pretty bearish right now, so it's hard to believe MATIC will go up in price anytime soon. Development is still happening behind the scenes, so it should only be a matter of time before Polygon becomes a "force to reckon with".
One thing for sure is that ETH 2.0 will benefit Polygon, as transaction finality will be achieved faster than usual. The only downside would be decreased security/reliability, due to the change in the main chain's consensus algorithm. But they (ETH + MATIC) will still be a better choice than other alternative chains. Price-wise, MATIC should be able to go up a little bit as new projects join its blockchain network. But the cryptocurrency will only achieve a new All-time-high after a bullish market. MATIC is pretty cheap right now so it wouldn't hurt to stack more coins before the excitement begins. Just my opinion
