0146 GMT - Bitcoin rises in early Asian trading hours, as risk appetite is improving after President Trump promised not to attack Iran before the midterm elections and unveiled a deal with Russia to secure more diesel. However, expectations for the Fed's policy path remains a key driver of cryptocurrencies' performance, says Antonio Di Giacomo at XS.com in a note. A potential pause in interest-rate increases could offer support, he adds. Higher borrowing rates tend to weigh on risk appetite, hurting cryptocurrencies. Bitcoin is 0.2% higher at $83,785.65.
