DO NOT PANIC!
This!
As a daytrader.... yes, the ones that normally never look past a 5 minute chart... I can't stress how important it is to look at the higher time frame levels first.
Just look at that chart you've posted above. If you saw that on another time frame, you'd be creaming yourself over how bullish the chart looks!
We all just need to take a deep breath, look at the higher time frame support levels that are ALL still in play and relax :)
While Segwit throws a bit of a spanner in the works, it's still just like any other news release that markets react to BEFORE the event. I wrote my latest piece on the market psychology behind this move in Bitcoin and why I'm still bullish so please check it out if you want some accompanying reading.
