If trump is to win the second term, he needs to do everything possible to bring this debt down rather than increasing it the more before they declare state of emergency on their economy, and I expect him to have been thinking of how they can take advantage of the new cryptocurrency to see what they can do about it.
I don't think Trump (or anyone else for that matter) can actually do anything to bring the debt down. It's already at a stage where you can calculate forward as to how much debt there is next month, next year, etc. The most they can do (realistically speaking) is to slow down the rate at which the debt is groing. The US is too far gone to actually reduce the debt. It's wishful thinking to expect that.
And no, I don't think that they have spent a second thinking about how they can benefit from crypto. Instead, they have spent their time thinking about how they can firmly regulate it.
