I'm writing a full analysis of Augur and REP tokens, and value comes down to two things-- market volume and market fees. Volume can be estimated in various ways, but I'm curious about calculating average fees. I've seen 1% thrown around in various places, and I know that there are measures in place to prevent 0% fees, but is there a way to calculate the floor on fees?
The incentives for people to hold and use REP depend almost entirely on how much the platform generates in fees, so I'm hoping to get as accurate an estimate as possible (or at least a few different possibilities). Any insight that could be provided would be much appreciated. As Augur grows and volume increases dramatically, will fees become much, much lower? Is there some sort of equilibrium for how much REP holders can earn?
