In my opinion the most important question to solve is: "What incentive does the customer have to use PINK and not just buy the product with BTC or fiat?".
 
 When compared to credit card payments the Pinkcoin advantage is obvious. The credit card company charges significant fees for example swipe fee, transaction fee, statement fee, monthly minimum fee and so on. The most risky one being the chargeback fee which would not occur when paying with Pinkcoin. These fees usually are hidden from the customer but the customer pays it because it's priced into the goods.
 
 If we could get some arrangement with the shop owner to give some percentage, let's say 2%, back to the customer it is a win situation for the shop and it is a win situation for the customer. It would be possible to introduce a structure to determine how much of it goes into charity for a good cause, how much is the advantage for the customer and how much is incentive for the merchant. If the customer consistently get's a 2% (this is just an example figure) discount on all purchases it would be a strong customer incentive to use Pinkcoin.
