The cryptocurrency's value plummeted by nearly a third last week, and was dealt another potential blow when the Israeli Securities Agency said it would bar companies trading in bitcoin from operating on the Tel Aviv stock exchange and investigate how to regulate the digital currency because of concerns about volatile prices.
