$BTC Bitcoin (BTC) as the first decentralized cryptocurrency pioneered blockchain technology. Its core value lies in its scarcity (with a limit of 21 million coins) and anti-inflation characteristics, making it known as "digital gold". However, high volatility, regulatory uncertainty, and energy consumption controversies remain major challenges. After the halving in 2024, the supply-demand relationship may drive long-term appreciation, but short-term market sentiment is easily influenced by macro policies. The entry of institutional investors (such as ETF approvals) has enhanced mainstream recognition, but to truly become a stable asset, issues like scalability (such as Layer 2 development) and practical application scenarios need to be resolved. The future may continue to evolve amidst the debate between financial innovation and speculative bubbles.
