Bitcoin Finds Robust Support Near $80,000
CoinDesk explains that Bitcoin’s price has rallied above $90,000, anchored by three cost‑basis metrics— the 2024 yearly volume‑weighted cost basis, the True Market Mean, and the average U.S. spot‑ETF cost basis— which together create a structural support zone around $80,000. Analysts note that the True Market Mean, reflecting recent on‑chain purchases, has held firm near $81,000 since October 2023, suggesting investors are likely to defend positions in any pull‑back. This confluence of metrics underscores Bitcoin’s resilience amid broader market volatility.
