 6  Bitcoin is a free open source peer-to-peer electronic cash system that is
 7  completely decentralized, without the need for a central server or trusted
 8  parties.  Users hold the crypto keys to their own money and transact directly
 9  with each other, with the help of a P2P network to check for double-spending.

18  depending on the speed of your computer and network connection, the synchronization
19  process can take anywhere from a few hours to a day or more.
