If you look at previous Bitcoin price roughly on the 21st of july BTC left a demand zone and spiked massively to the upside.
If we notice price has not yet tapped that zone and i feel that is the reason why the alpha cryptocurrency has refused to cross the 42 to 45k resistance area .

In my opinion i think BTC will still dip further more into the demand zone before we can see a new ATH on the asset.Thou we may still continue trading within the rising wedge area.

Purely my opinion and not financial advice.
