As I observe it, the answer is yes. First, ethereum is currently the second most popular cryptocurency. It gets a lot of attention just like bitcoin. Second, most start-up companies in ICO also make use of eth as their token due to smart contract technology. Everex is an example, goo.gl/E2NDF2

Perhaps, as we speak, eth isn't as a big threat but time only tells when it starts to rev up, and be a clear threat to the frontrunner.
