1, what is BTC
BTC stands for Bitcoin, a digital currency and one of the first cryptocurrencies to be introduced and widely used. Bitcoin was conceived in 2009 by a person or group of people using the pseudonym "Satoshi Nakamoto" and has been developed and promoted ever since. Bitcoin is a decentralised transaction and bookkeeping system via blockchain technology that allows users to conduct peer-to-peer transactions globally without the need for intermediaries. It is regarded as digital gold with a certain store of value and means of payment, and is widely recognised and used globally.
2、What are the advantages of BTC
Bitcoin (BTC) has a variety of advantages over traditional currencies and other digital currencies, some of the main advantages include:
1. Decentralisation: Bitcoin's transaction system is built on top of blockchain technology, removing the control and intervention of a central authority. This means that no single administrator or central bank can manipulate the issuance or value of Bitcoin.
2. Limited Supply: The total supply of Bitcoins is fixed at around 21 million, which makes Bitcoins a scarce resource. In contrast, many traditional currencies can be continually printed, leading to inflation.

3. Security: Bitcoin's blockchain technology provides a highly secure transaction system. Every transaction is recorded on the blockchain and protected by cryptographic algorithms, making Bitcoin transactions virtually impossible to tamper with or spoof.
4. Convenience: Bitcoin allows for instantaneous peer-to-peer transactions around the globe, and transactions are often faster than traditional financial systems. In addition, cross-border payments using Bitcoin are often cheaper and faster than traditional international transfers.
5. Transparency: Bitcoin's blockchain is open and transparent, and anyone can view transaction history. This transparency helps prevent fraud and misconduct, while also increasing trust in transactions.
Overall, Bitcoin's advantages include decentralisation, limited supply, security, convenience and transparency, which have made Bitcoin a popular digital currency and widely used worldwide.
