The “world’s largest shadow bank” BlackRock Inc. has said Bitcoin is a “scary” sign of “excess” in global markets. Speaking in an outlook presentation Tuesday and quoted by Bloomberg, the company’s global chief investment strategist Richard Turnill appeared to think the current downturn in cryptocurrency prices was little of a surprise. “When when we look for signs of excess in the market, I look at bitcoin and to me that looks pretty scary,” he told the audience.
