So you think that Cardano has the potential to take over ETH? More likely than other competitors like Solana or Polkadot?
Cardano, Solana, and Polkadot will not be able to take over ETH in the near future even though all three of them already have their own Blockchain in cryptocurrency, because ETH is neither a strange coin nor a coin that has no selling value in cryptocurrency, so this is very competitive competition hard for the three of them.
Although currently Cardano has become an alternative as long as Ethereum is experiencing a very expensive increase in transaction fees, but Cardano will never be able to take over ETH in the near future even though the project will continue to be developed, because so far ETH has gained high popularity and very strong fundamentals among other altcoins.
But Cardano is slowly closing up and issuing more and more projects (like I wrote above). If people already switch to BNB (see the current BNB price increase) because of the insane ETH transaction fees, I believe they would also like to switch to other alternatives, if ETH does not something fast about its fees.
