AI Market Summary
On-chain data shows $686M of BTC net withdrawn in a single day from Binance, Coinbase, and Bybit, materially above the 30-day average and among the largest recent daily outflows. Reduced exchange balances typically tighten readily available spot supply and can reflect increased self-custody or long-term holding behavior. The timing alongside BTC testing the $66K psychological/technical area reinforces near-term bullish positioning and sensitivity to breakout attempts.
