What Does the Bitcoin Weekly Close Say About a Trend Reversal?

Bitcoin closed the week ended September 20 above its 50-week moving average for the first time in 45 weeks, trading near $81,600 after gaining almost +1.5% over the week and +20% over the previous 35 days, according to CoinGecko data.

The moving average itself sits near $78,115, putting Bitcoin above a long-term trend line that had acted as a barrier during the decline.

That distinction, a weekly close above the average rather than a fleeting intraday move through it, is central to the technical case, and multiple analysts are all in agreement.

Galaxy Research found that Bitcoin avoided setting a new low after 11 of 13 previous weekly moves back above the 50-week average. The immediate question is whether Bitcoin can remain above the level long enough for the former resistance area to act as support.

Why the 50-Week Moving Average for Bitcoin Matters

The 50-week moving average calculates the average weekly closing price over the past year and indicates Bitcoin’s long-term trend. During price increases, Bitcoin typically trades above this average, while during declines, rally attempts often fail below it.

Galaxy Research views this average as a ceiling during drawdowns; once Bitcoin drops below it, recovery attempts usually fail until it reaches a market low. Conversely, successfully closing above the average has historically marked the end of bear markets, followed by significant price rallies.
