U.S. Senator and former Bridgewater CEO Dave McCormick has put as much as $1 million of his personal money into bitcoin as his committee prepares to enact cryptocurrency legislation. According to disclosures this week, McCormick has made several recent investments in the Bitwise bitcoin ETF, investing hundreds of thousands of dollars. The latest investment was between $310,000 and $700,000 last month, according to the disclosure. In February, he disclosed that he had invested as much as $450,000 in the Bitwise ETF, with a potential total investment of nearly a million. His investment represents most of Congress' action on bitcoin this year.
