BTC, or Bitcoin, is the world’s first and most popular digital currency, introduced in 2009. The main goal of Bitcoin was to provide a financial system that works without the control of any government, bank or institution. This currency is based on blockchain technology, which makes transactions secure, transparent and immutable.

The special thing about Bitcoin is that its supply is limited, meaning that only 21 million Bitcoins can be created in total. That is why many people also call it “digital gold”. Over time, Bitcoin’s popularity has increased and it is now being used as an investment, online payment and store of value.

Although BTC has brought financial benefits to many people, it is also quite volatile. That is why thorough research, understanding and caution are very important before investing in Bitcoin.

In short, BTC is a revolutionary step in the modern financial world that is laying the foundation for future digital finance, but it is extremely important to be responsible and knowledgeable in its use and investment.
