Bitcoin (BTC) : a revolutionary digital currency

Bitcoin is the first digital currency created in 2009 by a person or group known as Satoshi Nakamoto. Its goal is to enable transactions without going through a bank or intermediary.

This currency operates using a technology called Blockchain, which ensures the security and transparency of transactions.

Bitcoin allows you to send and receive money anywhere in the world quickly and securely. It is also limited to 21 million units, which can increase its value over time.

However, its price is quite volatile (we're talking about volatility), which poses a risk for investors. Today, Bitcoin is used worldwide, both as a payment method and as a long-term hold.
