#BTC重返12万 Bitcoin (Bitcoin, abbreviated as BTC) is a decentralized digital money that was proposed in 2008 by an individual or group using the pseudonym "Satoshi Nakamoto" and officially launched in 2009. It is the world's first successfully implemented crypto asset, operating on blockchain technology, and has the following core features:

1. Core Features

- Decentralization: The Bitcoin network is maintained by global nodes without the need for centralized institutions such as banks or governments.
- Constant supply: The limit is 21 million coins, with the issuance rate controlled by algorithms (approximately "halving" every 4 years). As of now (2025), over 19.5 million coins have been mined.
- Blockchain technology: All transaction records are on a public ledger, immutable, and transparent and traceable.
- Anonymity: Users trade through addresses without directly binding their real identities (but transactions can be analyzed).

2. Current Status (August 2025)

- Price Volatility: Influenced by factors such as market supply and demand, regulatory policies, institutional adoption (like ETFs), and macroeconomics (like inflation), Bitcoin's price may be in a high volatility phase. Specifics should refer to real-time data (such as CoinMarketCap).
- Mining and Halving: The fourth halving has been completed in 2024 (block reward decreased from 6.25 BTC to 3.125 BTC), and miners' earnings further depend on transaction fees.
- Layer2 Development: Scaling solutions such as the Lightning Network improve transaction efficiency and reduce fees.

3. Main Uses

- Investment/Speculation: As a high-risk, high-volatility asset, it has been included in the portfolios of some institutions and individuals.
- Payments and cross-border transfers: A few merchants accept Bitcoin payments, and the cost of cross-border transfers is lower than traditional banks.
- Anti-inflation tool: Some view it as "digital gold" to hedge against fiat currency depreciation.

4. Disputes and Challenges

- Regulatory risk: Different policies in various countries (such as the advancement of compliance in the United States, while some countries prohibit it).
- Environmental Issues: The energy consumption controversy of the PoW (Proof of Work) mechanism is driving mining farms to shift towards clean energy.
- Technical risks: Issues such as loss of private keys, exchange hacking, and other security problems still exist.

5. How to Participate

- Trading: Buying and selling through compliant exchanges (such as Coinbase, Binance) or OTC markets.
- Storage: Use hardware wallets (cold storage) or software wallets (like Electrum).
- Mining: Requires specialized equipment (ASIC miners) and low-cost electricity, making the entry barrier relatively high.
