I could imagine retirement homes where the residents sleep all week and just wake up for weekends or holidays, allowing them to extend their lifespan to see their descendants grow up.

Or you set a trigger with your fund manager. You put in 100K and tell him to wake you when you have $2m (in today's dollars) or less than $50K.

I was thinking of this today: enter stasis and set a trigger to emerge only once one’s wealth has compounded to place them within the vaunted ”top 1%” or leave one in cryosleep indefinitely.

Except so many people would do that that it might as well be a death sentence since the cryo fees would eat away at your money faster than it could grow compared to all of the other people in the world.

Cryo fees and compound interest are separate concepts. Just because the second is present, doesn't mean the first one will grow. The opposite is true: When more people want something, you scale up production (or someone else does) and the prices (generally) go down.

The change will probably be really hard on your body so you don't want to do it that often.

Another use case: helping immobile patients who are morbidly obese lose weight.
