As per my technical analysis, this bull run may last till $2000 prices regardless of what would be the result of bitcoin ETF will get. Because bitcoin already got sufficient media coverage to get enough new investors to reach there.
Bull run or no bull run, eventually the price will surely hit the $2000 since it's only a matter of time. However, the ETF approval might give the price a significant boost as it will allow institutional investors to enter the market. The effect of money from these investors flowing into Bitcoin should not be underestimated. If they jump into Bitcoin by great numbers, then even $2000 will be considered peanuts in the long term.
ETF will be finally approved, no matter in 2017 or later years, we can be very patient, and even without bitcoin, the price can be pumping significantly. I don't worry about the price.
