*Bitcoin: The First Revolutionary Digital Currency*
Bitcoin is the first and most famous decentralized digital currency launched in 2009 by an individual or group under the name "Satoshi Nakamoto". It relies on *blockchain* technology that allows transactions to be recorded transparently and without the intervention of third parties like banks.
The aim of Bitcoin is to provide a secure, fast electronic payment method that is independent of traditional financial systems. What distinguishes it is its limited number of units (only 21 million), giving it a rare character and increasing its value over the long term.
Bitcoin has experienced sharp price fluctuations, rising significantly and then falling repeatedly, making it a risky investment. Nevertheless, many see it as a *digital store of value*, and it is referred to as the "Gold of the Internet".
*How Bitcoin Works*: Bitcoin is traded over the internet using *blockchain*, a decentralized database that securely documents all transactions. Each transaction is recorded in a *block* that is added to the chain, which is known as the "blockchain". This ensures security and prevents tampering or forgery.
