The investment fund of billionaire George Soros, otherwise known as the man who “broke the Bank of England”, has reportedly started trading bitcoin.

Speculation that the storied investor’s firm has waded into cryptocurrencies stemmed from a 30 June report from TheStreet.com, citing two sources who said Soros Fund Management’s chief investment officer Dawn Fitzpatrick had given “the internal green light to actively trade bitcoin.” The firm is also looking at other digital currencies, the report said.
