Bitcoin extends gains above $82,000

The cryptocurrency was trading near $82,500, fast approaching its May high of $82,814. That level was first breached to the upside on Nov. 21 and then vigorously defended for several days before giving way on Thursday.

The focus is now on whether bitcoin can reclaim that level. A failure to do so would strengthen the immediate bearish outlook, as technical analysts typically view a rejected retest of a former support level as a negative signal.
