ETHEREUM has emerged as the main competitor to bitcoins crypto market dominance and analysts at Weiss Ratings have given ETH a more favourable score for potential profit than bitcoin and looking at the way etherium blockchain is been built where it gives room for many other coin to be built on its blockchain did you think, it can emerge as the most accepted coin later in the future than bitcoin and thereby overtaken bitcoin in price and value. 
I am sure that Ethereum may be more favored. Although Bitcoin is a market leader with tremendous market capitalization. However, Ethereum is equally well developed, with the implementation of fast and economical transactions. It is becoming more and more popular.
