Polygon and Stellar are altcoins that have potential and growth for the future, but if we follow the current development of Altcoins there are still many other altcoins that have large communities, and great developers and are supported by future use. such as ethereum, cardano, bnb and also for now what is trending is NFT. So I'm sure some of the altcoins I mentioned will have very good growth and have the potential to be even better.
