It is pretty hard for developers to find something comparable like ether. And there are hundreds of startups already investing like crazy in Ethereum. Why they gonna change that ? Only because of a Hardfork? Ethereum already done a Hardfork(some people say: Yeah but this was on the protocol level...). It actually do not matter at all. The community, The Foundation and all Startups want the Hardfork, and they will get it!
RE: Will the Ethereum Blockchain still be #2 after the Hardfork?
