As of my knowledge cutoff date (July 2024), Bitcoin (BTC) is a decentralized digital currency proposed by Satoshi Nakamoto in 2008 and officially launched in 2009. Bitcoin is based on blockchain technology and ensures the security and immutability of transactions through cryptographic algorithms.
### Key Features of Bitcoin:

4. **Global Circulation**: Bitcoin can be freely traded worldwide, without regional restrictions.
### Use Cases of Bitcoin:
- **Investment and Speculation**: Bitcoin's price volatility attracts a large number of investors and speculators.
