Bitcoin wavered near $11,000 on Friday, as Mark Carney, Bank of England Governor warned cryptocurrencies were failing as a form of money and needed to be regulated.
Bitcoin was trading at $10,872 up 0.45% as of 14:11 GMT on the Bitfinex exchange after hitting an overnight high of $11,151. Bitcoin has struggled to stay above $11,000 since it hit a two-month low of $6,000 in early February.
On Friday Carney warned that cryptocurrencies are a financial bubble and investors need to be protected.
“Cryptocurrencies act as money, at best, only for some people and to a limited extent, and even then only in parallel with the traditional currencies of the users. The short answer is they are failing,” Carney said in a speech in London.
