This looks pretty textbook. Price has been bound in a rising wedge for almost 3 months. Bearish div on the RSI. Volume going down. Looking for the price to break the support trendline and possibly come back to test resistance before continuing down. This is one possible way it could play out but it is virtually guaranteed it won't be exactly as shown.
In the longer term BTC is looking bullish so depending on how it bounces I'll be looking for a long setup after all the sellers and over-leveraged longs are flushed out.
A break of the resistance trendline would invalidate the setup.
