Bitcoin opens a new week above 80,000 dollars after briefly plunging towards 75,000 dollars during the Federal Reserve’s decision. The economic calendar seems lighter, but three appointments stand out: a series of interventions from Fed officials, the first US PMIs for September on Wednesday, and the meeting between Donald Trump and Xi Jinping on Thursday. Last week, the US central bank raised its rates by 25 basis points, for the first time since July 2023. The Bitcoin market must now digest this return of monetary tightening.
