Bitcoin is a digital and global money system currency. It allows people to send or receive money across the internet, even to someone they don't know or don't trust. Money can be exchanged without being linked to a real identity.

Bitcoin adoption and use continues to grow a lot every year. Since 2012, Bitcoin has gained the attention of the mainstream media; one way is the WannaCry ransomware created in May 2017. Adoption growth has not only happened for consumers, but also for many companies, who are looking to make use of all of the advantages of Bitcoin.

Bitcoin is a cryptocurrency and worldwide payment system. It is the first decentralized digital currency, as the system works without a central bank or single administrator. The network is peer-to-peer and transactions take place between users directly, without an intermediary.
