Bitcoin Mempool Congestion Eases as On-Chain Velocity Hits 18-Month Low

Mempool backlog has fallen 65% from its May peak to 45,000 transactions, but on-chain transaction velocity has dropped to 18-month lows, signaling a collapse in network demand.

⚡ EXECUTIVE 30-SECOND INVESTOR MATRIX

🎯 THE SIGNAL

Bearish for BTC near-term as declining on-chain activity undermines the fee-driven security narrative and points to waning retail and institutional usage.

📈 BULLISH VECTORS

Accumulation by long-term holders: entities with >1 year holding period now control 68% of supply, reducing liquid float and setting the stage for a supply shock when demand returns.

📉 BEARISH VECTORS

Miner capitulation risk: with hashprice at $45/PH/s and fees at 1.2% of revenue, miners may liquidate BTC holdings to cover operational costs, pressuring spot prices.

⚠️ PRIMARY RISK TRIGGER: A sudden spike in Ordinals or Runes inscriptions could reignite mempool congestion, causing fee volatility and disrupting normal transaction flow.
