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.
There is no actual competition that may happens on the economic state of one crypto-currency to another, it is much more a relation that shows direct development for one to another. It just like mutual relation which affects both variable to progress. And it's just like a mutual understanding that may cost for further development of each other. So it's better to continue our support for both cryptocurrency that may lead for further development and progress for the transaction, price, value, and of course security.
