I really doubt Eth reaches BTC ever. I think ETH will have a great year but don't see it passing BTC.
Yes and considering their gap as to market capitalization, price and dominance, ETH is way too far from BTC right now. Let's just say that ETH can reach 20,000$/ETH soon but for sure BITCOIN will even double that market price. So while BTC is around, I think it will remain as the alpha of the cryptocurrencies.
