Bitcoin has surged past the $88,000 mark, its highest since early April, driven by a weak EUR/USD and thin trading volumes. Meanwhile, Donald Trump has criticized Fed Chairman Jerome Powell, raising concerns about the Fed's independence as the central bank prepares for its May meeting. Investors are eyeing the $90,000 threshold, but ongoing trade disputes pose downside risks, with potential profit-taking at lower levels like $84,000 and $80,000.
