2025 Rewind: Bitcoin Hits $126K as ETFs, Institutions Power Bull Run

Bitcoin reached a lofty all-time high in 2021, thanks in part to the surprising support of traditional finance. Bitcoin’s journey in 2025 was nothing short of spectacular. The year saw BTC climb from around $87,600 in January to a historic all-time high of $126,200 on October 6. Institutional adoption, ETF inflows, and macroeconomic trends all played a role, cementing Bitcoin as the undisputed king of digital assets for the year. The peak didn’t last, however and Bitcoin pulled back, trading around $83,800 to $90,400 by early December. Bitcoin is surprisingly trending towards a -5% loss for the year, despite the all-time high in October. On the bright side, Bitcoin’s dominance is holding strong at roughly 57% of the digital asset market.  BTC 1Y Chart Source: Yahoo Finance  October’s perfect storm: what propelled Bitcoin to $126K October saw Bitcoin surge to $126K as multiple factors came together.
