To me, BTC seems to form a broadening wedge, a pattern that you rarely see on charts and that indicates rather emotional trading. I expect price to break the wedge to the downside soon, with a subsequent retrace to around 3750-3600, where it would find a lot of support (4h 200MA, Ichimoku cloud, VPVR). From there, there is a possible rally to around 4400 (resistance level and daily 50 EMA).
