Basically we could've written any number to attract the audience, but realistically we would've just introduced (pick a number)% inflation and lower the value of the coin.
in my opinion the rewards schedule, or lack of one, does more to lower the value than any amount of interest does.
There's nothing that brings the value down more than unstable network. We had to fix that first, before continuing with anything else. We will put the rewards schedule on our top priorities list, although in our case it'll be more prediction/estimation than schedule.
