The Bitcoin and other cryptocurrencies rate depends on many factors. The price is largely dependent on the demand and supply mechanism, which is further influenced by the limited number of Bitcoins that can be created. In addition, the price may change due to information about government policies towards cryptocurrencies, the support of crypto projects by large companies like Microsoft, as well as a result of growing acceptance of Bitcoin as a form of payment.
