For me, I don't think that Ethereum can beat Bitcoin as the Number One in the crypto market, it's because Bitcoin is getting more and more bigger each day because there are more investors coming every time and Ethereum still has a lot to improve in their blockchain and their security features.
I'm not believe look at the price gap between bitcoin and ethereum in the coinmarketcap, even if th price of bitcoin today are in the dip price between bitcoin and ethereum are almost 60 to 70 percent price higest gap of bitcoin vs ethereum.
