Bitcoin at key level ATH

In my opinion bitcoin is trying to brake throught the ATH 66k for a second time, after the last day during the last couple weeks it has been retesting the 60k support wich has proved to be a hard buy zone maintaining bullish momentum, my guess is that the bull run is on and it will brake 66k, taking into account that emerging ETFs will make more institutional capital sneak in the market. Disregarding that I'll, propose 2 scenarios: the most likely the bullish one, seeing the FIB level we can expect a run up to the 78k-80k area if BTC breaks the 66k resistance and settles above it will confirm the continuation of the bullrun. In case it doesn't break, we can expect a pullback to FIB level 0.618 at 50k wich merges with the upwards trend line, thus testing the bullish run.
