George Soros has previously stated that the rise of Bitcoin is based only on speculation. The words of the richest hedge fund manager, and one of the wealthiest people, in the world carry a lot of weight. But now the Rockefeller family – another giant of the American financial establishment – is joining the crypto-party. The venture capital arm of the Rockefeller Foundation, Venrock, has signed a partnership with Coinfund, a Brooklyn-based cryptocurrency investment fund. Venrock (a compound of “venture” and “Rockefeller”), is turning its sights to cryptocurrency projects and markets.
