The Bank of England sent a clear warning:

Sam Woods, the Bank of England deputy governor responsible for financial supervision said that “in their short history, crypto-assets have exhibited high price volatility and relative illiquidity.”

Writing in a letter to the chief executives of banks and insurers he said: "Crypto-assets also raise concerns related to misconduct and market integrity – many appear vulnerable to fraud and manipulation, as well as money-laundering and terrorist financing risks.”
