I'm more interested in Polygon than Solana. Besides we can use the same wallet as Ethereum or BSC. Many Dex platforms have been developed through the Polygon blockchain. This can help us in making transactions as well as in buying tokens from the Polygon blockchain. But Solana is also a good coin. But if we say competitor BTC, I also think it is still very far from expectations, because to compete with Ethereum alone is not yet capable, how can it compete with Bitcoin as the king of crypto.
