Bitcoin has value because it is useful as a form of currency. Bitcoin has the mathematical properties of money (persistence, portability, interchangeability, scarcity, severability, and legibility) rather than relying on physical characteristics (such as gold and silver) or the trust of the central authority ( Such as legal tender). In short, bitcoin is supported by mathematics. With these characteristics, what is needed for a monetary form to have value is trust and use. For Bitcoin, this can be seen in its growing base of users, merchants and start-ups. Like all currencies, the value of Bitcoin comes directly from people who are willing to accept it as a means of payment, and this is the only source.
