$BTC **Bitcoin (BTC) Core Value and Controversies: **

As the first decentralized crypto asset, BTC is based on blockchain technology, shaping its status as "digital gold" through the scarcity of a total supply of 21 million coins, becoming an alternative investment target resistant to inflation. Its price is highly volatile and is influenced by multiple factors including institutional holdings, regulatory policies, and market sentiment. After the halving in 2024, the rise in miner costs may support long-term value. However, the high-energy consumption mining model, regulatory uncertainties (such as the repeated approval of US ETFs), and challenges of technological iterations (such as Layer 2 scaling) remain controversial. Currently, companies like MicroStrategy continue to accumulate coins to reinforce the store of value narrative, while El Salvador's fiat experiment highlights the potential disruptive nature of decentralized currency. However, retail investors need to be cautious of leverage risks and market manipulation.
