Bitcoin surges past $77,000 on policy hopes

Bitcoin surged past $77,000, marking its best weekly gain in more than three years, as investors reacted to the Treasury's bond buyback plan and hopes for US crypto legislation.

The rally lifted the entire cryptocurrency market, with altcoins following suit.

Analysts attribute the move to a weaker dollar and increased institutional adoption.

Bitcoin's market cap rose nearly 7.5% in 24 hours.
