You've heard, perhaps, that the most recent nuclear weapons agreement between Russia and the United States has lapsed.

And look, nuclear weapons are nothing to turn a blind eye to, obviously.

But...

Nukes ain't the only race in town.

China and the United States are in a race of their own, each trying to dominate in cutting-edge technologies, robotics and AI, quantum computing.

Also, though, the energy to power all of those things.

And given that you can't do any of them without being able to plug them in, as it were, the stakes of the energy race might well be the most important.

Marketplace's Sabri Beneshour has more on that one.

This final note on the way out today in which the operative phrase is disorderly decline.

It's most often used in association with the dollar, as in the dollar going down for reasons everybody understands is fine-ish.

But when nobody can figure out what's going on and it falls a lot quickly, that is a disorderly decline.

The subject at hand today is not the dollar, but Bitcoin, which, while yes, still an almost entirely speculative asset, is nonetheless a sizable asset class.

Well, what we have this week in the OG cryptocurrency is a classic disorderly decline.

BTC against the dollar off as much as 14% today, 25% for the week, 31% the past 30 days, $63,000 and change per Bitcoin at one point on this day.
