Bitcoin uses peer-to-peer technology to operate, without central authority or central bank; transaction management and bitcoin publishing are done collectively by the network. Bitcoin is an open source; the design is general, no one is the owner and control of Bitcoin and everyone can take part. By its unique nature, Bitcoin enables ways of usage that other payment systems can not do before.

Maybe friends and friends want to try a business with bitcoin.
