polygon looked like try catching up with other platform that it try to follow like bsc. although right now most of people prefer to expect something big coming from cardano but i think polygon also have the same potential as cardano and same like solana. if cardano can reach the $2.7 polygon is also possible since the total supply of polygon is far less than cardano. polygon will need big platform for non fungible token like opensea to attract more investors and to make its price higher than $3 but thats not easy to build something like opensea.
The only advantage of Polygon I think compared to BSC is that it also builds for Ethereum,,, so all projects on ETH already bridge to Polygon whenever they need to take advantage of cheaper fees and faster transactions. In that sense, it will always have business rather than BSC competing to TAKE business from Ethereum.
