Bitcoin is money for the Internet. It is a scarce digital commodity used as money by millions around the world. People buy coffee with Bitcoin at local shops. Others get paid in bitcoin and use it to shop online. Friends use it to settle with whoever paid for dinner. Workers send Bitcoin back home to help family, regardless of where they live.
Bitcoin is money in true sense. It is a medium of exchange. The only thing new about it is the form in which it exists. I am talking about its digital form. But as far as we can buy stuff using anything, it becomes money and so does bitcoin. It is accepted by many as a payment for their offered services.
