The traditional model of most online marketplaces is to take a % fee for each sale, then rely on a payment processing system that will in turn also take % fee for each transaction like Paypal. Even those crypto currency payment systems such as bitcoin have % for each transaction. 

Citify, has thought it well, to create a payment system that does not takes away a % for each transaction.  A ZERO payment processing fee. This means that there will be more $$$ in the pockets of merchants who in turn can sell their products at a lower price for their products. 

Is there a need for a crypto currency on Citify? We think the advantages are there.
