Ethereum lost 2nd place in terms of capitalization, but this project continues its development, so the creators of Cardano need to prove their words - in practice.
ethereum is nice and i doubt that it can be obercome within few years so ylu will see that ethereum is one of the strongest right now
the State owned Cardano continues to undergo development and progress that continued to rise with the increase that regularly occur and improvements continued incrementally with a difficult situation. This ability makes the Cardano will be very capable to take over the Ethereum.
