That's something I've never been clear on myself, and would love to know. I should probably go re-read the whitepaper. I had a skim through it before I first signed up here, but I didn't really grasp the concepts at the time. It would make sense to me that it would have to decrease over time though because frankly 0.0066%/day is ludicrous.

If you look at the biggest whale accounts, they're earning mind boggling amounts per day in interest. That surely can't be sustainable?

On the other hand, I really love watching my balance, modest as it may be, go up.. I don't really want to see that slow down any :/
