Bitcoin held above $85,000 on Tuesday, near its highest level since January, retaining a 7% gain over five days and an increase of about 35% over three months. Softer crude prices, renewed institutional demand and corporate buying supported the advance. US spot Bitcoin ETFs recorded $433 million in net inflows on September 18, while Strategy resumed Bitcoin purchases after a three-week pause. Regulatory sentiment also improved after the US SEC (U.S. securities regulator) granted a five-year exemption to platforms using blockchain infrastructure to facilitate trading in tokenized stocks and other securities. The development came as the US Senate halted further progress last week on the Clarity Act, which seeks clearer digital-asset rules. Traders are also monitoring this week's US-China summit for progress on easing trade tensions and its potential effect on broader risk sentiment.
