The post Best Bitcoin (BTC) Days: Holidays Outshine Weekdays, Study Shows appeared on BitcoinEthereumNews.com. Lawrence Jengar May 14, 2026 06:39 CoinGecko’s analysis of Bitcoin returns reveals US holidays deliver 4x higher next-day gains than non-holidays. Mondays and New Year’s Day also outperform. A 13-year study by CoinGecko reveals a surprising trend: Bitcoin (BTC) purchases made on U.S. federal holidays deliver significantly higher next-day returns than any other days on the calendar. The analysis, covering 4,753 days from 2013 to 2026, found that U.S. holidays averaged a +0.77% return the following day, four times higher than the +0.19% baseline for non-holidays. Holidays like New Year’s Day, Columbus Day, and Christmas showed particularly strong next-day performance, with New Year’s Day leading the pack at an average +2.01% return and an 84.6% win rate (positive next-day performance in 11 of 13 years). This outperformance could be tied to broader market dynami
