Bitcoin is the first digital currency introduced in 2009 by a mysterious figure named Satoshi Nakamoto. Bitcoin operates using blockchain technology, which is a decentralized and transparent transaction recording system. The main advantage of Bitcoin is that it is not controlled by banks or governments, thus providing financial freedom for its users. However, its price is highly volatile, making it a high-risk investment. Currently, Bitcoin is becoming increasingly popular as an investment asset and payment method in various countries. Nevertheless, regulations regarding its use still vary in each region.
