no, SEC will most probably reject this ETF and any new ETF in the near future for about a year or two and will not change their stance against bitcoin and its ETFs anytime soon.
and no even if they approve this ETF there will not be any "big" bull runs because you can not change the trend with a simple news. what you can do is that the news can speed up the process. for example now we are in a fixed trend of accumulation then soon after a small rise followed by testing of resistance. and then we have bull run if the resistance is broken.
what positive news can do at this point is that it can speed up the accumulation to reach its end and the "small" rise to begin.
I read from some news and articles that the deadline for the review about Bitcoin's ETF will be on February 27, 2019, and I don't really think that they will approve this because they stand firm on what they believe about the manipulations of Crypto Currencies through exchanges and about those pump and dump group that circulates in telegram. Bullrun might happen even without that ETF thing but it only depends on the community's hyping and way of thinking, if the majority of the Crypto Community thinks and believes that the Value of Bitcoin might increase and the majority of the people keeps on hodling the price of Bitcoin has a very high chance to increase because of this same idea phenomenon.
Seriously. a positive news might affect Bitcoin's value and negative news affects it too just like we have seen the past years and months. So, there is a possibility that if the SEC approves the Bitcoin ETF there might be an increase in Bitcoin's value, just what I have said if the majority of the minds of the hodlers cooperate with each other skyrocketing isn't impossible. I do really think that the SEC will not approve the ETF of Bitcoin but who knows there might be a change of heart and point of view.
