Newcomers just entering the crypto circle are inevitably confused by professional terms like “arbitrage,” “breaking issue,” and “airdrop,” and often puzzled by questions like “how to make money in the crypto circle” and “where to find industry news.” In fact, mastering these basic concepts is key to getting started. Below is a compilation of core crypto terms and essential knowledge to help you quickly understand the logic of the crypto world.

1. What is the Crypto Circle?

The crypto circle, simply put, is an exclusive community of cryptocurrency enthusiasts, investors, and practitioners. It's not a mainstream public circle, but it gathers many core participants, with unique earning models inside—such as trading coins, ICO crowdfunding, mining, and other common strategies that are quickly practiced and spread within the circle. However, note that the proportion of people making money in the crypto circle is not high, and risks coexist with opportunities.

2. Common Ways to Make Money in the Crypto Circle

There are multiple profit paths in the crypto circle, with the core and mainstream ones including:

  • Trading Coins: Buying low and selling high digital currencies to earn the price difference, which is the most common method.

  • ICO Crowdfunding: Participating in blockchain project crowdfunding early to obtain tokens issued by the project, expecting future appreciation.

  • Mining: Running computing power through computers or professional equipment to obtain newly issued digital currencies.

  • Arbitrage: Exploiting price differences between different exchanges by buying on a low-price exchange and transferring to a high-price exchange to sell for profit.

3. Where to Find Crypto Circle News?

To stay on top of market trends and information in a timely manner, focus on two main types of platforms:

  • Market Data Websites: Feixiaohao, MyToken, AICoin, which allow real-time queries of prices, gains, trading volumes, and other data for various digital currencies.

  • News Websites: Jinse Finance, 8BTC Community, BiShiJie News, focusing on crypto industry dynamics, project developments, policy news, and more.

4. Comprehensive List of Core Crypto Terms

  • Fiat Currency: Legal tender issued by a country or government, backed by government credit, such as RMB, USD, EUR, etc., serving as the statutory payment tool in circulation in the real world.

  • Token: A core concept in the blockchain field, not simply a “coin,” but a proof of rights. It must satisfy three elements: a digital form of rights certificate (representing specific rights and intrinsic value), secured by cryptography for authenticity and privacy, and freely circulable and verifiable on the network at any time.

  • Opening a Position: A trader newly buys or sells a certain amount of digital currency, formally initiating a trade.

  • All-In: Investing all capital at once into a certain type of digital currency, which is a high-risk operation.

  • Airdrop: A common marketing method for cryptocurrency projects, where the project team distributes tokens for free to potential investors and users to promote and expand influence.

  • Hedging (Locking Position): After investors buy or sell contracts, if the market trend goes against their position, they open a new position opposite to the original one to hedge risks.

  • Candy: Tokens that digital currency projects distribute for free to users during the ICO stage, serving as a hype and promotional tactic by the project team.

  • Breaking Issue: When the market price of a digital currency falls below its issue price, for example, if a coin's issue price is $1 and it later drops to $0.8, it's considered a break.

  • Private Placement: A method for blockchain project founders to raise funds, also a pathway for investors to participate early, typically targeted at specific investment groups.

  • K-Line: Also known as candlestick chart or yin-yang line, drawn based on core data like opening price, highest price, lowest price, and closing price for each analysis period; it's a key tool for analyzing coin price trends.

  • Arbitrage: A colloquial term for cross-exchange arbitrage, buying digital currency on an exchange with a low price and transferring it to a higher-price exchange to sell for the difference.

  • ICO (Initial Coin Offering): Derived from the stock market's IPO concept, blockchain projects issue their own virtual currencies in exchange for mainstream virtual currencies on the market to achieve financing.
