Polygons potential in the future is good, because transaction costs are cheaper than BSC, but regarding the selling price it may not necessarily provide the best value, to compete with BSC is not the target for now, what Polygons needs to do is provide maximum selling value for now, considering the current BSC is still quite stable and promising in the market, so to compete with them is quite difficult.
Polygon still needs some updates to be able to compete with others because he himself is still very new in the crypto space so he will not be able to compete if he only relies on cheap gas costs because from past experience with Tron which also has very low costs but cannot compete with the ERC20 and BEP20 networks to date.
