The 200-week moving average is Bitcoin’s most famous long-term floor: the average closing price of the last ~4 years — one full cycle. In every bear market since 2015, price has bottomed at or briefly below this line, and it has never stopped rising, because each 4-year window still contains more adoption than the last.

When price trades far above the MA (100%+), the market is historically stretched; when it approaches or touches the line, it has historically been the deepest value zone of the cycle. Note the chart begins mid-2021 — a 200-week average needs 200 weeks of history, and reliable exchange data starts in August 2017.
