Bitcoin surged about 6% to around $77,370 on Friday, extending weekly gains to more than 20% for its strongest weekly advance in more than three years and reinforcing a breakout that earlier reached as high as $79,345.51 after a prolonged range largely between $60,000 and $70,000. The U.S. Treasury’s plan to at least double purchases of longer-dated government bonds pushed long-term yields lower and the dollar weaker, improving risk appetite, while President Donald Trump’s meeting with crypto industry leaders and call for progress on a crypto market-structure bill, alongside the Clarity Act and related regulatory optimism, supported sentiment. U.S. spot Bitcoin ETFs attracted more than $1 billion in weekly inflows, higher than an earlier reported about $606 million, and more than $2.75 billion in Bitcoin short positions were liquidated in a major squeeze. Ethereum rose about 5% to $2,384.78, and U.S.-listed crypto stocks advanced, with a newer report showing Robinhood up 12.98%, Gemini 10.03%, Coinbase 9.6% and Circle 9.25%. Despite the rebound, Bitcoin remained well below its October record above $126,000, and analysts questioned whether the rally can last without sustained new capital, spot demand and strong macroeconomic conditions.
