Bitcoin surged Friday on optimism over US cryptocurrency legislation and the US Treasury’s surprise move to buy back more of its own bonds, which fuelled a shift to riskier assets.

The world’s biggest cryptocurrency by market value climbed 6.9 percent to $77,675.94, after reaching its highest level since May, and is up more than 20 percent since Wednesday.

Friday was the third consecutive day in which bitcoin jumped more than five percent.

The sharp rise came after US President Donald Trump urged lawmakers on Wednesday to pass the Clarity Act, a bill to spur cryptocurrency use that has stalled in the Senate.
