Bitcoin's easiest trading days are disappearing.
In 2017, 11% of days had strong directional trends. In 2025, it's 3%.
Here's what's happening and how you should adapt.
First, How Do We Measure This?
Kaufman's Efficiency Ratio (KER) tracks how "clean" price movement is.
KER near 1 = strong trend. KER near 0 = choppy noise.
I tracked every day since 2014 where Bitcoin's KER crossed key thresholds.
Here's What the Data Shows
KER > 0.5 = market moving with moderate direction. KER > 0.75 = market moving with strong direction.
The table tells the story year by year.
Moderate Trends
Moderate trends (KER > 0.5) have declined, but gradually.
27% of days in 2014 → 21% in 2025.
Not dramatic. Bitcoin still trends. Just slightly less often than a decade ago.
Strong Trends
But look at the strong trends (KER > 0.75).
This is where the easy money lived.
2017: 11% of days with powerful, clean trends. 2025: 3%.
Now you can see why it was difficult to make large profits on directional BTC-only trades in 2025.
Volatility Is Vanishing Too
But trendiness isn't everything. Traders also need volatility.
Look at how Bitcoin's big moves have disappeared:
Days with 10%+ swings (over 10 days):
- 2017: 56.6%
- 2025: 10.1%
Days with 20%+ swings:
- 2017: 28.2%
- 2025: 0%
The explosive moves that made Bitcoin tradeable are vanishing.
The Broader Market
This is why systematic traders shouldn't limit themselves to Bitcoin.
The broader crypto market still offers the volatility and trend clarity that Bitcoin had in earlier days.
