Not sure, how you can make commerce, cryptocurrencies and charity work together but I'm interested to see, what'll come out of this.
As I guess, the main objective of this project is charity. Commerce is for loyalty program (encouragement of donators). Blockchain technology (cryptocurrencies) is needed to make p2p platform more decentralized, safety and clear.
The mix of commerce and cryptocurrencies will help to increase the number of donors.
