President Donald Trump may have defended his family's cryptocurrency ventures this week, but the bigger story for investors isn't the billions tied to crypto—it's what his administration wants crypto to become.

Speaking Thursday, Trump said there was "nothing illegal" about his family earning more than $1.4 billion from cryptocurrency ventures and reiterated that the United States must remain the global leader in both crypto and artificial intelligence to stay ahead of China.

Those comments fit neatly into a much broader policy vision the White House has been building for months.

And that vision isn't centered on Bitcoin (CRYPTO:$BTC).

It's increasingly centered on the U.S. dollar.
