I dont think so that Ethereum can reach the value of BTC , atleast not now , not today that ethereum value are suffering and going dip. Ethereum is a potential token but what we see now is not normal in a token that competing to btc for a long period of time.
Ethereum may be second in terms of its stability and prominence in the market next to bitcoin. But I don't think it can surpass btc in terms of its price.Especially now wherein eth is experiencing down the dip. But we can't know for certain what would happen in the future, of course.
