I, myself is hodling polygon(Matic token) because I have foreseen a very high potential for this altcoin to be like SOL that happen to pump massively last year.
I am agree with your opinion, between BNB and ETH prices increasing as the year goes by, it will result in expensive gas fees for the BSC and ERC20 blockchain, and I think people will migrate to Polygon, causing Matic prices to rise significantly, just my humble opinion.
