There could be a doubling in price if the ETF goes through on the 11th of March.
I think much of the expected ETF "price boost" is already priced in in the actual price level. It's even possible we will see a short correction around March 11 ("Sell the news"). But nevertheless I expect a continuing of the uptrend if the ETF is approved, but if 2000 can be broken has to be seen (I expect a major correction just before $2000).
If the ETF isn't approved then focus will return to the outcome of the scalability debate. Segwit had a minimal increase in support in the last 2 weeks (about 3-4 percentage points). If this rate continues then we can see the critical 50% level in about 2 months and that would be positive, but it could also be simply a statistic deviation. If the stalled situation continues I expect a downtrend at least well into triple digits.
