I 100% believe that ethereum follows bitcoin instead. People do not realize that whenever something major happens it is usually bitcoin that goes up first and then we see every altcoin moving accordingly, doesn't matter if it is ethereum doesn't matter if it is 12432421th marketcap coin, ALL altcoins go together whenever bitcoin moves.
That's bitcoin advantage, being the prime mover, everyone depends on it, trading pairs obviously. Although there are times that ETH move by itself, bitcoin is not left behind. And then when bitcoin goes up, everyone goes up as well.
This is why ETH is not different from any other coin. Obviously we are talking about something that is as cool as it gets because ETH is getting so much better that people are talking about ETH fighting against bitcoin itself, that is why I honestly believe that this is a good thing, since ethereum is second that means if we see eth and btc fighting each other that is only something good for all of crypto. At the end of the day, we need to applaud any try to beat bitcoin since if we see them all get better that is all the better for us.
If bitcoin is the king of crypto, Ethereum is the altcoin version. However, I don't think at this point we will see coins that will overtake bitcoin, not ETH and not any in the top ten coins.
