Bitcoin climbed again Friday, reaching its highest since late March.
The cryptocurrency briefly rose more than 6.5 percent over the last 24 hours to a high of $8,204, its highest in more than two weeks, according to Coinbase.
Bitcoin traded near $8,111 as of 11:56 a.m. ET Friday, up 18.9 percent for the week.
The gains followed a sudden spike Thursday from a low of $6,786 to above $8,000. The move forced traders who had bet against bitcoin to buy back into the market, or cover their shorts.
