5.) Permissionless: You dont need to ask anybody to use cryptocurrency. Its just a software that everybody can download for free. After you installed it, you can receive and send Bitcoins or alternative cryptocurrencies. No one can prevent you. There is no gatekeeper.

Unlike traditional currencies, that can be issued by central banks, Bitcoin has no central monetary authority. Instead it is underpinned by a peer-to-peer computer network made up of its own users machines, akin to the networks which underpin BitTorrent, a file-sharing system, and Skype, an audio, video and chat service. Bitcoins are mathematically generated since the computers in this network execute tough number-crunching tasks, a procedure known as Bitcoin mining.  The mathematics of the Bitcoin system were set up so that it gets increasingly more difficult to mine Bitcoins over time, and the total number which can ever be mined is limited to around 21 million.
