0714 GMT - Bitcoin edges higher, trimming last week's declines caused by increased expectations of the U.S. Federal Reserve raising interest rates during Wednesday's policy decision. Higher rate-rise expectations have boosted the dollar and reduced the rally in dollar-alternative assets. However, bitcoin remains well below the psychologically important $80,000 level. Bitcoin rises 0.3% to $77,590, below the three-month high of $82,163 reached on September 4, LSEG data show.
