rcoin is not only a P2P currency (like bitcoin) and not only having a demurrage fee (like Freicoin), but it is also a communal coin, which is re-distributed equally between the community's members. As it is communal, it can buy only nearby things, whereas the remote things can be bought using money by the community. In each re-distributing cycle, it can be liquidized by equally distributing money instead of rcoin. The community is not only defined as a region, but by the relations of its members. Such communities can be build up and be opened up by the comcom contract, which allow another option liquidizing. Click on "Terms & Reasons" for the contract and on "Join" for creating your contract.
