December 3rd, 2018 (-15.13% difficulty adjustment)
This date almost coincided with the
official bottom of the last bear market (which is really, really interesting)
Initially, in the 12 days that followed, Bitcoin sank down another -21%, but once it bounced from that bottom,
it never looked back.
One could argue that the bullish price action continued on a steady (albeit slow) pace up until the great market crash in 2020 (when all hell broke loose)
