The number of BTC is much less than the number of FTC. Why did you decide to put such a big number of FTC in circulation?
This is very legacy.
Bitcoin was the first coin and started with 21 Million
Then litecoin forked and multiplied by 4, so 84 million
then Feathercoin originally forked the Litecoin code base and again multiplied by 4 so 336 million
--
Now Feathercoin is a direct fork of Bitcoin with all the necessary Feathercoin parameters added.
Hope that helps.
