I think Cardano's scientific approach will create a new Altcoin.
Cardano is a much more complete blockchain, now we can only look at the top of the aisberg but in the future I think it will provide a solid foundation for what is to come.
but the solid foundation of cardano is not as strong as ethereum in any way. such as market capitalization. Ethereum market cap is very strong in the crypto market. I see if Cardano has to really prepare everything carefully to be able to overthrow ethereum and still have to take a long time.
