Chart is self explanatory. This first (purple) trendline is a critical trendline to watch now. It has been tested frequently. If it breaks, then the support levels and fib levels testing may begin.
BTC has repeatedly failed to break (or sustain above) the 72k USD mark.
BTC price can go back up from here, but if this trendline breaks, the correction could be deeper. It will then open the door to 56k support zone testing or even 46k support zone testing.
No trading advice, neutral stance.
