It's an interesting idea. Did you write something to explains how it produces and maintains an economy?
That's not to say the amount distributed can change in some obvious way. My current thinking is that if person A, B, C say person X gets money, then they get the same "agreed upon" (or fixed) distribution as everyone else.
On the other end the coins that are created have a "depreciation" built in. Something that depreciates 100% in 5 years won't appear too valuable. But something that depreciates over the course of an entire lifetime will feel plenty valuable to the people who are the original recipients. So in other words my current target is 100 years.
