**Understanding Bitcoin: The First and Most Popular Digital Currency**
Bitcoin is a cryptocurrency that was launched in 2009 by a person or group of people known as Satoshi Nakamoto. Bitcoin is considered the world's first successful digital currency and the most widespread and widely used.
**How does Bitcoin work?**
Bitcoin technology is based on a concept called “blockchain”, which is a public ledger that records all Bitcoin transactions that take place across the network. These operations are encrypted and grouped into groups known as “blocks.” Transactions are then confirmed and blocks are added to the blockchain by a group of users known as “prospectors” or “miners.” Once a transaction is confirmed, it cannot be modified or cancelled, making Bitcoin an unforgeable and safe currency to use.
**What distinguishes Bitcoin?**
- Decentralization: Bitcoin is not controlled by any central entity such as governments or central banks, which makes it independent and separate from the traditional financial system.
- Global spread: Bitcoin can be used anywhere and at any time without the need for permissions or authorizations.
- Security and Privacy: Bitcoin transactions are secured by complex encryption
