Key bitcoin price levels to watch as downward pressure builds

As bitcoin remains in a downtrend, several technical and onchain levels stand out as critical areas of support. What to know : The 100-week moving average at $87,145 remains the main line of defense. Below this, the cost basis of U.S. spot bitcoin ETF buyers at $84,099 has provided support during recent consolidation. A sustained break below $80,000 would likely open the door to a revisit of the April 2025 low near $76,000.
