Detailed introduction

Bitcoin is a decentralized digital currency proposed by Satoshi Nakamoto in 2008 and officially launched on January 3, 2009. Here are the main features of Bitcoin:

1. Decentralization : Bitcoin does not rely on central institutions, and transactions are conducted through a peer-to-peer network and jointly maintained by global nodes.

2. Blockchain technology : Transactions are recorded on the blockchain, each block contains multiple transactions, linked in chronological order, ensuring transparency and tamper-free.

3. Limited supply : The total amount of Bitcoin is capped at 21 million, and it is gradually released through "mining". Mining is the process of verifying transactions and obtaining new Bitcoins.

4. Anonymity : Users conduct transactions through addresses without providing their true identity, but transaction records are publicly verified.

5. Global circulation : Bitcoin can be traded globally without geographical restrictions, fast transaction speed and low fees.

6. Great volatility : Bitcoin price fluctuates violently, and is affected by market supply and demand, policies and other factors, and investment risks are high.
