MMM is a community of people providing each other financial help on the principle of gratuitousness, reciprocity and benevolence. We use BITCOIN crypto-currency in our transactions. In MMM you don't have to make contracts or pledge your property. In MMM there are no lenders and no debtors. Everything is very simple: one participant request for help - another participant provides help. http://mmmglobal.org/?i=triplerdm
