Why is Bitcoin suddenly rallying?

Bitcoin jumped toward $73,000 after a sharp rebound from about $63,000, which it hit after the weekend US and Israeli strikes on Iran.

ETF money is helping drive the rally, with US spot Bitcoin ETFs taking in more than $680 million over the past two days.

Risk mood improved as stocks climbed and oil stayed steady on signs the Iran conflict could be shorter than people feared, which helped crypto catch a bid.
