The price of Bitcoin on the Luxembourg-based Bitstamp exchange has now fallen by more than half from a peak of almost $20,000 hit in December. Last week it suffered its worst weekly performance since 2013.
British bank Lloyds Banking Group on Sunday said it was banning customers from buying Bitcoin using credit cards. It joined US banking giants JPMorgan Chase & Co and Citigroup who announced similar bans on concerns the lenders could be held liable when the volatile currencies plunge in value.
