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.
If Ethereum doesn't solve its GAS fee issue, it might well become a stumbling block for it.
