A must-read for newbies! Over 50 encryption terms explained in one article.

Just entered the crypto world and confused by all kinds of terminology? We can help you clarify. From the basics of blockchain, wallet, and private key, to exchange, mining pool, and smart contract, and then to the latest DeFi, NFT, and oracle—these terms are actually not that mysterious.

Core concept: Blockchain is a decentralized ledger, Bitcoin/Ethereum are encryption currencies, and miners verify transactions through PoW/PoS mechanisms. Wallets are divided into hot wallets and cold wallets, the private key is your absolute authority and must not be leaked.

Trading Level: CEX is a centralized exchange like Binance, requiring KYC; DEX is a decentralized exchange, enabling peer-to-peer transactions. There are also financing methods such as ICO (Initial Coin Offering) and IEO (Initial Exchange Offering).

Market Terminology: ATH is All-Time High, ATL is All-Time Low, "to the moon" is a surge, FUD is fear, uncertainty, and doubt, HODL is holding long-term. A single move by a whale can shake the market.

Risks to be aware of: Pump&Dump is a typical market manipulation where a group of people drives up the price and then dumps it, leaving later retail investors with significant losses. Those who are stuck are called "bagholders."

Advanced Concepts: DeFi is a decentralized financial ecosystem, including lending, liquidity mining, etc. NFTs are non-fungible tokens, each unique. Layer 2 (Lightning Network) can significantly reduce transaction fees.

Remember these, and you can basically understand the crypto circle when people boast.
