I'm not a mathematician but I think your models assumption that coin
loss is proportional to number of coins misses something, correct me if
I'm wrong but as value of coins goes up is it not reasonable to expect
coin loss to go down as people are more careful (not to mention
improvements in tooling and education).

Is it really possible to model coin loss as exponential decay
considering such things (I'm not being facetious, that is a real
question, like I said I'm not a mathematician)?

Cheers,
Tobin.
