Do you think Cardano will replace Ethereum?
Personally, I think that both blockchains will develop in different directions in the future.
Both blockchains would therefore be relevant and coexist.
I personally think of something like this:
Ethereum = DeFi
Cardano = dApp
I also thought of something like this:
Ethereum = NFT & Gaming
Cardano = dApp & DeFi
why are you asking something when you know there is a different direction between ethereum and cardano. how can they change positions from different directions. so I think both work in their own direction. and nothing can replace ethereum or cardano in cryptocurrency. and I agree that the two will coexist in the future.
