tl;dr?
I seem to have missed the part where you explain where the yield comes from.
Naturally, because I never explained it
Presumably from trading fees, worker proposals, and so on, but it wasn't something that I really wanted to get in on the post.
Rather, the main question was .. does it even make sense to have yield (for smartcoins), in terms of sound economics.
And while I wouldn't mind if my bitUSD magically grew for essentially doing nothing, it does seem unsound: other than using Bitshares, I'm taking pretty close to zero risk (black swan) holding the funds there - the same way holding a dollar bill doesn't give you any interest.
And we are hailing this sort of technologies as digital
cash, right?
