$BTC Bitcoin is a type of digital currency that uses encryption techniques to control the creation of new units and to secure financial transactions. It was invented in 2008 by a person or group under the name "Satoshi Nakamoto". Bitcoin is traded on a decentralized network called "Blockchain", which is a distributed public database that records all transactions and ensures transparency of operations. One of the unique characteristics of Bitcoin is that it is not affected by the financial policies of countries or central banks, making it an independent means of payment. While some consider Bitcoin to be a long-term valuable financial investment, others see it as subject to significant fluctuations in value. Bitcoin is used in various fields such as e-commerce, international money transfers, and some industries that accept digital currencies. However, due to the unregulated nature of Bitcoin, it faces challenges related to laws, taxes, and security breaches.
