Bitcoin extended this month’s losses in Monday trade as investors shied away from risk assets amid a more hawkish outlook for Federal Reserve policy tightening. The largest cryptocurrency slid as much as 3.3 per cent to $38,223, the lowest since March 15, and down more than 20 per cent from last month’s high. It was little changed after paring the earlier loss. The second-biggest coin, Ether, slumped to $2,799, a level not seen since March 18.
