Bitcoin (<a href="https://yellow.com/asset/btc" rel="noopener noreferrer nofollow">BTC</a>) closed the fourth quarter of 2025 with its second-worst Q4 performance on record, highlighting how sharply market momentum <a href="https://yellow.com/news/why-bitcoins-holiday-lull-could-be-setting-up-a-bigger-move" rel="noopener noreferrer nofollow">deteriorated after October’s peak.</a>
Data from Coinglass <a href="https://www.coinglass.com/today" rel="noopener noreferrer nofollow">shows</a> Bitcoin fell 23.07% in Q4 2025, a result that sits far below its historical fourth-quarter average return of 77.07% and median return of 47.73%.
The only worse Q4 performance in Bitcoin’s history occurred in 2018, when prices collapsed 42.16% during the depths of the previous bear market.
The weak quarter capped a turbulent end to the year that contrasted starkly with Bitcoin’s long-term seasonal pattern, where Q4 has historically been its strongest period.

Since 2013, Bitcoin’s fourth quarter has typically delivered outsized gains, often coinciding with post-summer recoveries and year-end risk appetite.
Coinglass data shows that Q4 has produced positive returns in the majority of years, with several triple-digit advances during prior bull cycles.
That pattern broke decisively in 2025.
After hitting record highs earlier in the quarter, Bitcoin reversed sharply, erasing gains and closing the period with a double-digit loss.
The -23.07% return places Q4 2025 as a clear outlier against historical norms, surpassed in severity only by the 2018 capitulation.

<a href="https://yellow.com/asset/eth" rel="noopener noreferrer nofollow">Ethereum</a> mirrored Bitcoin’s weakness, recording a 28.28% decline in Q4 2025.
According to Coinglass, this ranks as the fourth-worst fourth quarter in Ethereum’s trading history.
While Ethereum has also tended to benefit from strong year-end performance in past cycles, Q4 2025 instead reflected broad-based risk aversion across digital assets, with losses extending beyond Bitcoin into major altcoins.

The magnitude of Q4 losses has reshaped how investors assess late-cycle risk.
Historically, strong fourth-quarter performance has reinforced bullish sentiment heading into new years.
In contrast, the sharp declines seen in both Bitcoin and Ethereum in Q4 2025 highlight a market that entered the final months of the year under sustained pressure rather than recovery momentum.
With Bitcoin posting its second-worst Q4 on record and Ethereum logging one of its weakest year-end quarters, the data exhibits how exceptional the 2025 finish was relative to more than a decade of crypto market history.
