I'm stacking Bitcoin, but I'm increasingly unsure of what I'd ever spend it on.

Bitcoin will maintain its purchasing power, or even steadily rise in purchasing power, but the price of everything will also crash down.

Bitcoiners will have more money than they could ever spend, so most of it will end up just retiring, when they die. I suppose. I suppose that's how it'll redistribute. People will simply not spend it and it will become dead keys.
