Not completely sure if this will happen. It just seems so super obvious that I will critise my own "idea" here. Plus this setup is probably posted everywhere on the internet already.
But a retest is most of times an indicator that we get another leg down (towards fib 0.618)
A scenario to consider in our bullish week and the reason why we sold 10% crypto this week (of total 42%).
If it happens, you are glad that you sold so much in profits.. to do some shopping in the 35-20k BTC zone.
