$BTC Bitcoin (BTC), as the first decentralized cryptocurrency, has become the "digital gold" due to its scarcity (maximum limit of 21 million coins) and blockchain technology. Its price is highly volatile, influenced by institutional entry, regulatory policies, macroeconomics (such as interest rate hikes by the Federal Reserve), and market sentiment. The 2024 halving event highlights its deflationary attributes, but concerns remain regarding the high-energy consensus mechanism and scalability debates. In the short term, it has significant speculative attributes, while in the long term, it serves as an experiment in value storage against fiat currency inflation, with its future direction depending on the global regulatory framework and the development of the Layer 2 ecosystem.
