In fact bitcoin going parabolic has been happening for over a year, maybe 2 years. It looks like a straight line on a log price scale.
I think bitcoin is reaching a danger zone. Top of this channel marked by an Andrews pitchfork only been breached a couple of times followed by steep corrections.
Bullish scenario, bitcoin breaks up above the channel and goes hyperbolic in full on bubble mode, god knows how high, ending with full on epic crash.
Bearish scenario, bitcoin corrects down a few hundred dollars and continues its merry path along this channel.
