We expect that GGCurrency can be launched in six months from launch of this website (May 2015).  That would mean late in 2015 we will be ready for a launch of the currency system. It will take a year or more for GGCurrency to be "widely accepted".  But as with Bitcoin, there will be slow initial growth, growing faster and faster until it is accepted widely, similar to Bitcoin.  This will be affected by the external economy, and by the number of local economies which choose to integrate into this system.  A strong national economy would cause delayed acceptance of GGCurrency.  Weaker national economy and more strong local economies would decrease the time required.
