Thanks.  We're tentatively planning on 20 billion units, but we might increase that.  We would prefer to have more supply to keep the per coin value down so people don't have to work in units of milli or micro coins.

We plan to use something similar to the Ethereum model, where the bulk of the currency will go to a non-profit Foundation and be distributed through a public currency exchange.  We are also planning to have a limited opportunity for mining where people who help mint the currency will be rewarded with some portion.  Details will be announced shortly, after our next beta release.  If you want to make sure you don't miss it, you can subscribe to our newsletter at CredaCash.com

Thanks much for the interest!
