To be fair, every coin has ATH, and that's rarely not in the past. Would you say that none of them would go back to ath? Because i've seen some insane recoveries, and 464.8% needed for Polygon new ATH is nothing compared to them.
And polygon has lots of good fundamentals and big companies backing it. My favorite is of them definitely that reddit has adopted nfts as avatars and they are only using matic (or should i say pol already?
A recovery is indeed possible, but at the same time it is understandable that those that have held MATIC for a few years are worried about the lack of recovery, as there were some positive signs at the beginning of this year and now the price is lower than their expectations, so those long term investors are worried a new ATH may not be reached, forcing them not only to lose a lot of money, but wasting years of their time when they could have invested in another coin that actually brought them profits.
