Although the "Golden Fork" or "Fibonacci Fork" can be used in it's most simplistic format which is simply multiplying the circulation by the golden ratio and rationing the extra coins for the purpose of inflation, there are more subtle techniques that can be employed in smaller increments while at the same time maintaining the relationship to the golden ratio. in the case of bitcoin which has a circulation of 21,000,000 we have several Fibonacci increments to work with below the 13,000,000 coins. Namely 8, 5, 3, 2, and 1 Million.

http://frass.woodcoin.org/the-saga-of-the-lukeaudi-fibonacci-relation/This conversation I had with funkenstein_ of woodcoin shows a relationship to the Fibonacci numbers that I think is relevant and could potentially shed more light on other smaller, more incremental, changes that could be implemented over a time period while ultimately achieving the same ratio.
