According to online reports, Naeem Aslam, an analyst at Zaye Capital Markets, pointed out in a report that Bitcoin prices fell due to U.S. regulatory uncertainty and widespread risk aversion putting pressure on cryptocurrencies. A cryptocurrency summit held at the White House on Friday did not reveal any details of President Trump's plans to regulate the industry. Aslam said markets are also responding to concerns about global trade tensions and expectations that the U.S. economy may weaken.
