Bitcoin has spent the past month doing something the market has been waiting to see: staying on the right side of a trend line that has often separated prolonged declines from more durable recoveries.
On the week ending Sept. 20, Bitcoin closed above its 50-week moving average for the first time in 45 weeks. Alex Thorn, head of research at Galaxy Research, described the move as a potentially important sign that the market’s long decline may be behind it and that a new advance could be taking shape.
The timing is hard to miss. Bitcoin gained nearly 6% over the week and was trading around $81,000, bringing its rebound over the previous 35 days to about 29%.
The important detail is not simply that Bitcoin moved above the average. It finished the week there.
Bitcoin trades continuously, but its weekly candle closes at 23:59 UTC each Sunday before the next one begins. Analysts generally give more weight to a daily or weekly close above a major moving average than to a short-lived move that merely crosses the line.
Why Bitcoin’s 50-week line has become such a big deal
The 50-week moving average is exactly what it sounds like: the average of Bitcoin’s weekly closing prices over roughly the past year.
For traders and market watchers, it is often used as a simple gauge of the cryptocurrency’s longer-term direction. Bitcoin has tended to spend stronger stretches above the line, while rallies during extended declines have frequently stalled underneath it.
Galaxy has characterized the average as a kind of ceiling during major Bitcoin drawdowns. Once the price slips below it, efforts to reclaim the level have historically failed until the market is closer to a lasting low.
When those reclaims do stick, the consequences have sometimes been dramatic.
Galaxy reviewed major Bitcoin declines dating back to 2011 and found 13 occasions when Bitcoin closed a week back above its 50-week moving average. In 11 of those cases, the cryptocurrency did not go on to establish another low, suggesting the deepest part of the decline had already passed.
The historical examples are striking.
After the 2011 crash, Bitcoin reclaimed the average in January 2012. The decline was effectively over, and the cryptocurrency later surged roughly 600-fold, climbing from about $2 to a then-record high near $1,200 in late 2013.
Following the 2014–15 downturn, Bitcoin moved back above the line in October 2015 and did not return to the cycle low. From roughly $200, it went on to rise about 100-fold before reaching a record near $20,000 in December 2017.
The pattern appeared again after the 2018 crash. Bitcoin reclaimed the average in May 2019 and did not revisit the December 2018 low. From around $3,200, it eventually climbed roughly 22 times to a record above $69,000 in November 2021.
After the 2022 market bottom, Bitcoin crossed back above the average in March 2023 and stayed above it for more than two years. From a low near $15,500, it later posted an increase of roughly eightfold, reaching about $126,000 in October 2025.
The multiples are approximate because early Bitcoin price records are inconsistent. More importantly, they do not prove that moving above the 50-week average caused any of those rallies. They simply show what happened after previous successful reclaims.
Bitcoin has broken this signal before
There is an important wrinkle in the pattern, and it comes from one of the most turbulent stretches in Bitcoin’s recent history.
Two of the 13 reclaims did not hold. Both came between late 2021 and early 2022, when Bitcoin briefly moved above the average before reversing and eventually falling toward $16,000.
Galaxy identifies those failed crossovers as Dec. 26, 2021, and March 27, 2022.
That history makes the latest move more interesting, but also more conditional. As of the reference article’s latest figures, Bitcoin was trading near $81,450 while the 50-week moving average stood at about $78,115.
The gap is meaningful, but the real test comes next. Bitcoin would need to remain above the average in the weeks ahead for the latest reclaim to resemble the more durable examples from previous cycles.
Based on that historical record, the latest move is consistent with the possibility that the recent low was established near $60,000. It also leaves open the prospect of Bitcoin pushing toward new highs.
But the moving average is not a crystal ball. The signal has worked often enough to command attention, while its past failures are a reminder that one weekly close is not the same thing as a guaranteed change in direction.
