BTCUSD near term Retrace watch: Bitcoin to test 3900 ?

Quick plot to see if this ABC retrace plays out.
This is a lot of support in the 3900-3928 zone.
If it holds, then we have a shot at break of 4.2k.

We are also up against the previous Negative Impulse plotted here:

Prior to that, I had anticipated the top at 4.2k

Comment:

well this just became more likely, with a burst of market sells breaking the 1.618 support
