Ok. time it got rejected, but I do believe they will submit a new request. So, the ETF could be accepted right in 2018. I'm positive that sooner or later the SEC will accept the Bitcoin ETF
Unless Bitcoin removes all principles and traces of its original purpose, it's not going to happen. The SEC were very clear on their concerns about fraud and money laundering carried out with Bitcoin, and these are realistically part of the Bitcoin network and they are not things that are just going to magically disappear (rightly so, to be honest).
