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
Cardano will not be able to replace Ethereum. because we can see that the ecosystem in Ethereum continues to develop rapidly. Not only in Layer 1 but layer 2 is also developing rapidly, such as Arbitrum which is also continuing to develop. ADA actually also has its own advantages. So I also think that both will go side by side and have their respective advantages and disadvantages.
Both of them have their strengths and weaknesses, but i see that those weaknesses and strengths will complement each other (if only they work together) i noticed a lot of things that would be mutually beneficial to each other that you might also realize.
