the 100% POS returns for how long, annual or monthly?
I am not sure myself but I think you misinterpreted what that meant. If that is the case, we will get flooded with ODN in a very short while...you don't want that.
This is what I think (and I could be mistaken). In most POS/dPOS, you don't get 100% of what was "mined"...only certain percentage (say 80%) that could later (depending on difficulty level) translate to say 10% of your coins annually. In this case, if my interpretation is correct and based on my example, you get about 20% more annually than the regular POS/dPOS.
