Bitcoin is dropping again after weekend plunge, down another 5 percent on price manipulation concern

Kate Rooney

Bitcoin dropped 5 percent to its lowest level since February following reports of price manipulation. The digital currency fell below $6,200 Wednesday and has struggled to regain footing after dropping 10 percent this weekend. Prices began stumbling after a study was released by the University of Texas saying most of bitcoin's rise last year was due to price manipulation on popular exchange Bitfinex.
