We are seriously considering doing this with Nitrous and the whole thing, but you are right that its the 1 ENG per active user that holds us back. If we get the influx of users we hope to get but the revenue doesn't balance out we could get thrashed.
So we're waiting to see how Weedcash and the other early communities go. If their token sales prove profitable enough to get them a solid reserve of ENG for future bills, cool, we're in too.
