If Cardano would like to replace ETH, then the price should increases without following up the ETH either the Bitcoin.
I agree with you, to say Cardano will replace eth does not mean anything. Every new coin is looking to replace the ETH but they have to improve themselves a lot. EOS would replace the ETH.
Yes it's true, EOS to date has shown potential for it, not Cardano. If indeed Cardano will replace ETH, the coin should have gone up at this time. It has been around four months since the news came out. Ah, actually I'm also upset when I see the current cryptocurrency fluctuations. Hopefully soon there will be enlightenment.
