**[Bitcoin Down 23% Over First 50 Trading Days of 2026, Marking Worst Start to a Year in History]** According to a report by Jinse Finance, Bitcoin has fallen 23% over the first 50 trading days of 2026, marking the worst annual start in recorded history. In January, Bitcoin dropped 10%, followed by a further 15% decline in February. If the downward trend continues, this will be the first time in Bitcoin's history that it has recorded consecutive monthly declines (January and February), and it may also set the weakest consecutive monthly performance since 2022. On-chain data platform Checkonchain noted that in typical down years, the average index reading on the 50th day is 0.84, while the current reading is 0.77, highlighting the significant magnitude of this pullback. Notably, Bitcoin fell 17% in 2025. Historically, post-U.S. presidential election years tend to perform better overall compared to election years and most other years of growth, making this sustained weakness particularly striking.
