Top 10 coins. Yes, that's generally if I mention top 10 or top 100 coins that have good potential, because that's the truth in my opinion. In particular, the ones with good potential are BNB, Cardano, Solana, Polygon. Not to match Ethereum, but they have potential like Ethereum.
Of course, it's not easy to compete with ethereum at this point and I totally agree with you, but being a partner to complement each other, where the current need is there must be an alternative as a necessity that is really needed.
Of course, the top ranking in CMC/CG is very reliable to be used as an alternative, such as BNB, ADA, SOL, DOT maybe now can be considered, but all decisions and analyzes you can do yourself to make sure whether it is correct and can be used as a guideline.
Ethereum is increasingly unmatched by other Altcoins under it now, but it should also be realized that the coins that are under Ethereum are now always trying to approach Ethereum by using many new ways to make it very easy for each of them.
It's normal for all coins to try to be the best, even though their intention is maybe to be an alternative so they can take some of what has been on ethereum so far. but to be able to replace it is definitely not something easy when viewed from the market capitalization of ethereum is already very high. maybe in the future they will be able to get a better portion.
