Bitcoin will change a lot more than finance. It could also change how software is built and upend a bunch of today's biggest web companies and Bitcoin was designed this way to make sure that the same Bitcoin, which has no physical form, isn't spent twice by the same person.
Bitcoin will change alot but not everything....Although Bitcoin will become a famous and Popular but it cant change everything...Bitcoin can change the lifestyle of users but cant change the whole status of life of one person or user.
It could, bitcoin could just replace dollar, bitcoin could be a currency that we will be able to pay everywhere, bitcoin could just bring new look of payment in nearest years.
