2 billion coins has been said before. I think PPC estimated that they will create roughly 100M coins until it becomes too difficult. Yacoin is creating 13-15M coins per year. Unless the rate is too high for it's popularity in future I wouldn't worry about it.


In other news I created a Yacoin mining profitability Google docs spreadsheet. Thanks to aso118 from Yacointalk for the initial idea.

Other than the actual math the most speculative part of the calculations are the hashrate guesses.
