I dont think ETH will reach bitcoin price, in my opinion bitcoin is just too mainstream to get dethroned for the most expensive cryptocurrency category. One thing i believe on though, is that in 2018 Ethereum will rise more percentage wise than bitcoin, so that being said, in my opinion you will make more money if you have your money on ethereum than if you have your money on bitcoin.
Yes i do exactly think the same that ethereum would never reach bitcoin price and i do think ethereum is more profitable than bitcoin. bitcoin already too high and dont think the price will ever reach more than 20k $ anymore. ethereum have been uses by many businesses and it will survive cause they offer real project and already have a lot customers. i do believe ethereum atleast could reach 1200 $ in few month.
