Non one can tell who will be the winner in this crypto race, but Ethereum does pack a punch due to its innate mode of investment for ICO's. Bitcoin however is up to actual mass adoption and as a mode of payment platform accepted in a lot of countries, so I think Ethereum has a long way to go before it can actually overtake Bitcoin. There are also a lot of DAPPS that are quite strong fundamentally, so ETH might fail in some way if they can't solve their own issues.
