Coinffeine

Coinffeine is an open source project that enables exchanging fiat money for bitcoins in a decentralized, anonymous and secure way.

Based in Spain, Coinffeine is an open-source, P2P bitcoin exchange platform that enables its users to purchase and sell the digital currency in countries, including Russia, China, Indonesia, Brazil, and the Eurozone. The platform uses bitcoin's decentralized nature to create a secure way for people to exchange the digital currency with an untrusted third party. Coinffeine is not currently charging fees from its clients for the services provided by the company and does not handle its customers' funds. By not handling or holding customer's bitcoin or fiat deposits, Coinffeine is not required to enforce know-your-customer guidelines, simplifying user registration and lowering operational costs.
