Here are some other key points about the cryptocurrency world:

Consensus mechanism: rules and methods to ensure that nodes in a blockchain network reach consensus, such as proof of work and proof of equity.

Decentralized applications (DApp): various applications developed based on blockchain, covering multiple fields such as finance, games, and social networking.

Token: a digital certificate that can represent a variety of rights or values. In addition to being a currency, it may also represent equity, points, etc.

ICO (initial coin offering): a way for project parties to raise funds by issuing digital tokens, but there are greater risks and regulatory issues.

IFO (initial fork offering): a new currency is generated by forking the original digital currency.

Blockchain browser: a tool for viewing transaction records, block information and other data on the blockchain.

Node: each computer participating in the blockchain network, jointly maintaining the operation of the network.

Cold wallet and hot wallet: cold wallets are usually devices for storing digital currencies offline, with higher security; hot wallets are connected to the network, which are relatively convenient to use but have certain security risks.

Hash value: a unique identifier calculated by a specific algorithm, used to verify the integrity and consistency of data.

Air coin: a digital currency that has no actual value or application scenarios and is issued purely for the purpose of making money.

The cryptocurrency world is a complex and evolving field. You must remain rational and fully understand it when you approach and participate in it.
