Mathematical Proof the Bear Market is Over?

This is the log of the difference between the 80 Week SMA and the 20 Week SMA and its first derivative (slope) on the BTCUSD chart

The white line = [log(80 W SMA - 20 W SMA)] and the red and green waves are the first derivative of said measurement.

This measurement quite clearly indicates that we are moving out of a bear market and into a bull market.
