"USD valuations would also be created via quorum and an average price over a period of 7 days would be used to stop people from attacking the implementation. (e.g. if you dump 10000 coins right before the budget is finalized, you could drop the price by 10% and get 10% more coins as a result, right? To stop this we’ll use quorum based averages)."

Evan,

Can you please explain a little more how this will work?
thanks
