1W chart shows a descending triangle which is usually a bearish pattern. One characteristic of a descending triangle is a contraction of volume which is evident in the chart. Upon breakout volume spikes up. If it breaks out of this pattern, BTC might be going lower to mid 4,000's. Bollingers are also pinching which means volatility is impending. The bulls need to step in for a reversal, all signs point to trouble for BTC.
Descending triangles/wedges are actually bullish by textbook definition. I think you're referrig to an aescending wedge. It could very well break down though. At this point it's anyone's guess.
