For the first time in history, people are no longer dependent on the currency and financial systems of their country. The world has a global currency, that allows anyone to set up an account and transact on the network regardless of who they are and where they live. More people in the world have mobile phones than bank accounts. These people are able to access the internet but are unable to open a bank account or apply for loans. Without a bank account, there are billions of people excluded from the financial systems that many of us take for granted. Bitcoin has no exchange rates and no expensive international transaction fees. Bitcoin is the first truly inclusive, global world currency that transcends political and socioeconomic borders. In the next few chapters, we’ll cover the history of Bitcoin and a detailed look at how Bitcoin works.
