Bitcoin gained 23.47% over the five sessions through Friday, its strongest weekly advance since March 2023, rising from roughly $62,800 Monday to above $77,000 by Friday morning. The rally followed two developments in Washington: the Treasury said it would at least double long-dated buyback operations to $4 billion apiece starting Sept. 9, while President Donald Trump urged the Senate to pass the CLARITY Act during a meeting with crypto executives at the White House. The bill would define whether digital assets are securities or commodities and faces a procedural vote Sept. 15. About $2.7 billion in crypto short positions were liquidated as prices accelerated. Bitcoin remains about 40% below its October 2025 record.
