This is a bit more than a blip. It's a crash. This makes sense considering the huge November-December rally which inflated the price above what it should naturally be. This crash isn't quite a price correction, but the result of this crash will most likely be a correction above the floor and below where it was over December and January.
Someone with better analysis skills than I should form a strong estimate of where exactly the floor will be. If we know the floor we can make some estimates of where the price will be corrected to.
Besides of the TA, I think that people feelings will make BTC hit the 20k ATH in a reasonably short time of/when it survives all the FUD being spread right now.
