In the weekly chart, Bitcoin is showing a descending wedge. Current price is under the pressure of the threshold around 9300.
The reversal since this March is powerful, but I don't consider the chart as a pennant. In the past 4 weeks, it has been hesitating for too long to be a pennant.
The future 4 weeks are quite a decisive period for Bitcoin, if it fail to break out 9300, it'd most likely to retest 8000.
