You posted in 2021, it's 2023 now, and the price of the MATIC coin hasn't experienced a huge price increase, so I think the reason is because the competition in crypto is getting tougher.
maybe it's because bearish, honestly there are many coins that isn't having some rise like even eth and bnb, they just stuck same with matic.
even like that they have higher chance of rising that other coins in general because it's the one that has significant growth compared with other coins of the same niche.
even before beraish arrives, matic was about to break out and make some good increase but it was getting cancelled out quite literally by bearish and collapses of many platforms.
