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.
Basically Ethereum is one of the best altcoins and that is without a doubt,
the opportunity to overtake Bitcoin I think will always be Ethereum but again it's not easy and if it does it doesn't look like it will be anytime soon,
what is clear is that we will see what will happen in the future.
