TOKYO -- Bitcoin suffered its biggest weekly loss for the year amid a string of regulatory setbacks, posing fresh challenges in broadening the appeal of cryptocurrencies.
The price of bitcoin fell to $3,447 on Sunday, its lowest level since last September, according to CoinDesk, bringing the fall for the week to 30%, its biggest seven-day slide this year. On Monday, it pared back some of the losses, trading at around $4,000 by afternoon trading in Tokyo, less than half the $8,400 achieved in July.
