At the moment I am considering BNB with a potential similar to that of ETH, because it is managing many projects through its BSC network, which makes it one of the best networks for NFT games and projects, of course it is not equal to ETH, but if it is approaching because in a short time it is reaching a great value, of course we have to wait when btc falls to see how it continues to behave, but so far it has gone very well, and another that I see with great potential is Solana, because it is entering one of the most favorite currencies for investors, besides that it is giving very good returns, I think it has great potential.
I agree with you that BNB and SOL have close to ETH potential, as they both perform as well as ETH. Especially BNB which as you said has a BSC
which provides almost the same service as the ETH network. So it's no wonder some new projects are starting to choose to use the BSC network
over ETH, maybe because BSC has much cheaper transaction fees than ETH. But when compared overall still better ETH, especially with
the existence of ETH 2.0 it makes ETH even more difficult to beat. So until now ETH is still the best altcoins and is always in second place under BTC.
So it is very unfortunate if we do not include ETH in our portfolio, if we have enough capital, there is no harm in investing not only in BTC
and ETH. However, we can include BNB and SOL into our portfolio as well.
