Previously, the tense US-Iran situation and the anticipated disruption of shipping through the Strait of Hormuz would increase global market uncertainty, prompting funds to flow into safe-haven assets like Bitcoin and gold, supporting price increases.

Trump's statements directly reduced the risk of large-scale conflict in the Middle East and shipping disruptions, causing a rapid cooling of safe-haven demand. This would directly weaken the short-term buying momentum of Bitcoin and even trigger profit-taking, putting downward pressure on prices.
Concurrent effects: Crude oil prices would fall due to eased shipping risks, inflation expectations would marginally weaken, the Federal Reserve's rate cut expectations would be delayed, and the US dollar index would strengthen, further bearish for Bitcoin priced in USD.
