I think 2017 and now are different cases. Many compare this cycle to 2015 and now to 2013 when we btc got pumped, then there was a retracement, but actually each cycle is different. Btc has a very thin chance to drop below the previous low of this cycle - $3200- but it may stuck above the previous accumulation level of around 5800-6500 for a while. If we respect the timing, then more time needed for it to go parabolic. But as the each of the cycles is different, parabolic move can't be excluded.
