Since its inception in 2009, Bitcoin (BTC) has gradually developed into the most representative cryptocurrency globally. Its decentralized nature means it is not controlled by governments or financial institutions, and it ensures the transparency and security of transactions through blockchain technology. As global awareness of digital currencies increases, more and more institutions and investors view Bitcoin as digital gold for asset preservation. However, Bitcoin's price volatility remains significant, influenced by market sentiment, policy changes, and technological developments. Additionally, despite Bitcoin's limitless potential, it still faces challenges such as regulation and energy consumption. In the future, whether Bitcoin can become a mainstream global payment tool remains to be further observed.
