Bitcoin dips below $81K amid institutional sales and pending US crypto regulation.

Bitcoin fell slightly below $81,000 following a rally to three-month highs, driven by Strategy Inc.'s plan to sell some holdings to pay dividends. This move by a major institutional holder has caused caution among investors. Meanwhile, the US is pushing for a key crypto regulation bill with a July 4 deadline, which could bring more ETF inflows but also stricter rules. Altcoins showed mixed results, and Coinbase's upcoming earnings report is closely watched as a market health indicator.
