Bitcoin plays a complex role in the global macroeconomy. As a decentralized cryptocurrency, it operates outside traditional financial systems, offering an alternative store of value and medium of exchange. Its fixed supply (21 million coins) contrasts with fiat currencies, making it a potential hedge against inflation, especially in economies with unstable monetary policies. Bitcoin’s volatility attracts speculative investment, while its blockchain technology enhances transparency and security in transactions. However, its limited adoption, regulatory uncertainty, and energy-intensive mining process challenge its scalability and integration into mainstream economics, positioning it as both a disruptor and a niche asset.
