ETH is already the second best Cryptocurrency in the world, and I dont think there is any other cryptocurrency that can compete with that. Ripple seems to be competitive, but not to the level of competing with BTC and ETH
I can only beat other cryptocurrencies. But I dont think ETH will take down BTC from the first position, my reason for saying that is because BTC is the first to be released and that will make it the first choice for people, cause whenever people are talking about investing on cryptocurrencies, Bitcoin is always the first in their mind. So I dont see anyway that ETH take on it. it is acknowledged everywhere throughout the world and there is a change for the exchange expenses and handling.
