Dec 9 (Reuters) - With a series of record highs and crushing sell-offs, 2025 has been a rollercoaster ride for bitcoin, the world's largest cryptocurrency, which is at risk of ending the year with its first annual decline since 2022.
The world's main stock benchmarks have also had a turbulent year, repeatedly hitting record peaks and then pulling back as worries over tariffs, interest rates and a possible AI bubble whipsawed markets. While equities are mostly up year-to-date, bitcoin's overall correlation with share prices has strengthened markedly this year.
