Bill Pulte， As the director of the Federal Housing Finance Bureau nominated by Trump, he took office after being approved by the Senate in March this year. After working for less than three months, he issued an executive order requiring Freddie Mac and Fannie Mae to accept Bitcoin as collateral. Trump (and his staff) is really pushing forward to build the United States into a "crypto city". Of course, Bitcoin itself is also compatible. What liquidity is real estate and what liquidity is Bitcoin? High liquidity assets can certainly serve as collateral for low liquidity assets.
