Bitcoin revolutionized digital finance by enabling decentralized, borderless transactions without intermediaries. It is often referred to as "digital gold" due to its fixed supply of 21 million coins, which creates scarcity and helps hedge against inflation. Bitcoin’s adoption has led to the development of an entire cryptocurrency ecosystem, influencing financial markets, central bank policies, and investment strategies. As a decentralized asset, Bitcoin provides financial sovereignty, allowing users to control their funds independently of banks or governments.
