Bitcoin crossed $80,000 for the first time since mid-May, rising 4 per cent, driven by improving liquidity expectations and lower regulatory risk.

The US Treasury's decision to double repurchases of long-dated securities to at least $4 billion boosted risk appetite and supported the rally.

President Donald Trump's push for Congress to pass a "fair version" of the Clarity Act strengthened expectations of easier institutional participation in crypto markets.

Progress on the Clarity Act could spark a broader digital-asset recovery, though political impasse risks keeping market volatility elevated.
