¿What is the Bitcoin?
Bitcoin is a global cryptocurrency and digital payment system called the first decentralized digital currency, since the system works without a single central repository or administrator.
It was invented by an unknown programmer, or a group of programmers, under the name Satoshi Nakamoto and released as open source software in 2009. The system is point-to-point, and transactions are made between users directly, without intermediaries. These transactions are verified through network nodes and recorded in a distributed public ledger called blockchain.
In addition to being created as a reward for mining, bitcoin can be exchanged for other currencies, products and services. As of February 2015, more than 100,000 merchants and vendors accepted Bitcoin as payment. Bitcoin can also be maintained as an investment. According to research conducted by the University of Cambridge in 2017, there are 2.9 to 5.8 million unique users who use a cryptocurrency wallet, most of them with bitcoin.
