I see Solana climbing up to the third position but I do not think it will replace Ethereum. Just like Bitcoin will never replaced by any crypto, including Ethereum, Ethereum will never be replaced by any crypto including Solana.
In my opinion, Solana had great potential, but now there are many projects that are ready to replace it, so there is no question of replacing even ethereum
I think several things about Solana, I think it is a great Blockchain with great potential, but they must fix internal problems in a blockchain, such as network crashes or congestions, although I think they have not had this problem in quite some time, another problem is its low decentralization, some pros are that it has transactions with extremely low fees and I think it is the fastest blockchain of all, in addition to having quite a lot of adoption
