ethereum is the next bitcoin, and it will not be replaced by cardano. I think etherum will not be replaced, at this time when the price decreases even ethereum still exists.
I also think so. ethereum are strong enough to defend its position and its position, up and down price is not a bad sign. basically, the ethereum was able to show that he is indeed the coins did not disappoint, coins that are able to survive and live with the surge in prices is becoming increasingly improved.
