You shouldn't see it as a threat from the price perspective because It means nothing, you should however see how much Its mentioned on the news, how many shops (local and online) use it, how many ATMs does it have, how active the development is etc. Bitcoin wins in all these things beside Ethereum is not meant to be an electronic cash but bitcoin is.
Yes those are the facts that support bitcoins in our wolrd. Eth is just starting to bloom, compared to btc which are way too far from it. It is the most powerful crypto currency, it can be exchange into a real money using banks. While on the other hand eth cannot be converted into cash using banks, you will exchange it into a different medium. Which is less reliable than btc can give.
