So determining the value of bitcoin is not the question at stake here.
Suppose there's a new bitcoin with a production algorithm that's tied to the feedback rule proposed by McCallum and adjusts according to a datafeed of Nominal GDP. http://en.wikipedia.org/wiki/McCallum_rule
Part of the feedback rule linked above is the variable of Velocity. It's pretty straightforward to calculate it. http://en.wikipedia.org/wiki/Velocity_of_money
Can anyone provide a straightforward answer? Velocity will have to be calculated in a way other than simple bitcoin days destroyed since the velocity figure from this calculation would be far too high if actors transfer between personal wallets.
edit: topic=46241.0 <-- thread on bitcointalk discussing velocity as well. (Won't let me link directly)
