Would Nvidia see their lucky day and operate like any rational iffy actor? Sure. But I think it's important to be clear on the fact that demand suddenly exploded with crypto, and then kept going.
Nvidia may not be a saintly actor, but let's be sure to not ignore the laws of supply and demand. But! I feel my grasp on the matter is fairly basic, and I'm sure there are other points that may add nuance here - and highlight uncool practices by them. But there are only so many foundries; they take a lot of time to spin up (to the chagrin of every nation state); and when demand goes up, prices generally follow.
Nvidia did a great job at engineering a central bank-style AI funding bubble for as long as possible. Unfortunately, Cisco did the exact same thing.
Before, there was denial about the circular financing bubble, now look at them believing that a crash is coming.
