Bitcoin is the first global decentralized currency. It is powered by blockchain technology, a chain of segments of high security practically unmodifiable, therefore transactions are ensured safely in transit. Bitcoin uses peer-to-peer transactions through the network without central authorities or banks. Bitcoin is also open-source software; anyone can participate since no one owns or controls it. In 2009 it was made public for the price of $0.09. Ever since, its price has increased by thousands of dollars, making it a volatile asset.
Bitcoin is a poor candidate to be used as a currency for pricing goods or services since it is an experimental, non-official currency with appealing improvements and challenges. Each individual should be aware of government regulations and mandates required before making any purchase.
