What is Bitcoin ?
Bitcoin is a cryptocurrency, a virtual currency designed to act as money and a form of payment that is not controlled by a person, group or entity, thereby removing the need for third parties to participate in financial transactions. It rewards blockchain miners for the work done in verifying transactions and can be bought on multiple exchanges.
Bitcoin was introduced to the public in 2009 by an unknown developer or group of developers named Satoshi Nakamoto. Since then, it has become the most popular cryptocurrency in the world. Its popularity has inspired the development of many other cryptocurrencies. These competitors will try to replace it as a payment system or use it as a tool or security token in other blockchains and new financial technologies.
