The long-term value of Bitcoin (BTC) as digital gold, being the leader in crypto assets, is still promising due to its scarcity (total supply of 21 million) and global consensus. Although short-term fluctuation is influenced by market sentiment, regulatory policies, and other factors, historical data shows that significant pullbacks are often followed by new highs. After the 2024 Halving, supply will further decrease, and the long-term holding (HODL) strategy remains a choice for many investors. Continuous entry of institutions (such as through ETFs) and macroeconomic uncertainties (such as inflation) may drive BTC to become a safe-haven asset. Short-term fluctuations are inevitable, but the underlying logic of Bitcoin remains unchanged: decentralized and anti-inflation digital gold.
