# Bitcoin's Easiest Trading Days Are Disappearing

 Research • Pavel Kycek • February 3, 2026

 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.
