In altcoins, if you are investing in Ethereum and new projects, it is safe to choose to invest in Ethereum. Among altcoins, Ethereum is like Bitcoin. There are also many sayings that Ethereum will surpass Bitcoin. All I can say is that Ethereum and Bitcoin work differently and they don't need to compete with each other. And they each have a lot of fans.
even though I do agree that ethereum have smaller chance of ever overtaking bitcoin throne but if it's ranked based by capitalization then it could be said that ethereum and bitcoin could become a competition.
the thing is that, they are indeed in different niche but we are comparing the market valuation of each these coins, so it's still apple to an apple comparation.
