Bitcoin Posts First Post-Halving Annual Decline, Ending 2025 Below Opening Level

Bitcoin closed 2025 below its January 1 opening price, marking the first annual decline in a post-halving year, BlockBeats reports. The latest halving occurred in April 2024; BTC reached $126,000 on October 6 before falling over 30% from that peak. Bitgrow Lab founder Vivek Sen said the four-year cycle is dead, while investor Armando Pantoja and 10x Research's Markus Thielen argued institutional flows and macro factors now shape cycle dynamics.
