Starting with the most common—FOMO stands for “Fear of Missing Out,” describing the fear of missing out on profitable investments.

Then there’s LFG, which stands for “Let’s F***ing Go”—an expression of high enthusiasm showing excitement or positive momentum in community conversations. When someone shouts “LFG!” in forums or social media, it means they are very excited about something, usually a price surge or positive news about a project. Understanding LFG is important because it reflects the energy and optimism driving the crypto community.

Yield Farming is a strategy to earn income by providing assets to DeFi liquidity pools. Liquidity Pool is a pool where users deposit tokens to facilitate decentralized exchanges.

Mining is the process of earning new cryptocurrency as a reward for validating transactions. Gas Fee is the transaction fee on networks like Ethereum, usually measured in Gwei (0.000000001 ETH). Smart Contract is a program that automatically executes contract terms on the blockchain. These Smart Contracts enable developers to create decentralized applications (DApps).

Blockchain and Infrastructure Terms:

Cross-chain supports interoperability between different blockchains. Oracle is a system that provides real-world data to smart contracts.

Understanding Coin Classifications: Altcoin, Shitcoin, Meme Coin, and Air Coin

Altcoin: Innovation Beyond Bitcoin

Altcoins collectively refer to all cryptocurrencies except Bitcoin—they are alternatives to Bitcoin. They mainly emerge to improve certain features or provide functions Bitcoin lacks. Many altcoins adopt different consensus mechanisms, such as Proof of Stake (PoS) used by Ethereum or Delegated Proof of Stake (DPoS) used by EOS.

Some altcoins focus on increasing transaction speed and reducing costs for everyday payments. Ethereum is one of the most famous altcoins, introducing smart contract functionality that allows developers to create decentralized applications. Others are designed for specific community needs, like supporting DeFi services or governance.

The diversity of altcoins offers many options but also carries different risks. Investors should understand the technology, team, market position, and potential risks before investing.

Shitcoin: When Innovation Turns to Speculation

Shitcoin is a term for cryptocurrencies considered to lack substantial content, often just minor variations without significant innovation. They are characterized by a lack of innovation or uniqueness, driven by hype and market sensation, with little long-term support plans from developers.

Such coins are vulnerable to market manipulation, lack transparency, and pose high investment risks. While the term is often used critically, some coins may have potential or community backing. Deep research and risk assessment are crucial before investing.

Meme Coin: Internet Culture Meets Cryptocurrency

Meme Coins are cryptocurrencies created based on internet memes or pop culture elements, characterized by their humorous, entertaining, or satirical nature. Their value and popularity are closely tied to social media activity and internet trends.

Meme coin communities are often very active online, promoting through social media. Since prices are heavily influenced by community sentiment, market performance can be highly volatile. Many lack clear practical use cases—they are more internet culture products meant to entertain.

Dogecoin (DOGE) is the most famous meme coin, originally created as a parody of Bitcoin featuring the Shiba Inu dog logo. Over time, Dogecoin gained thousands of loyal followers and was openly supported by Elon Musk. Meme coins highlight the fun side of crypto culture while showcasing unconventional market volatility.

A notable phenomenon is the “golden dog”—when meme coin prices like DOGE jump dozens, hundreds, or even thousands of times, suddenly changing their status in the public eye. Besides Dogecoin, PEPE and Shiba Inu (SHIB) are also popular meme coins praised by communities.

Air Coin: Castles in the Air Without Foundations

Air coins refer to cryptocurrencies believed to lack real value, support, or practical application—just castles in the air, based only on hype and names without solid fundamentals. They are usually not backed by strong business models, technological innovation, or practical use cases. Most of their value depends on market hype and false propaganda.

Investing in air coins is very risky because their prices are susceptible to manipulation and highly volatile. Development teams are often opaque and sometimes involved in scams. These coins can disappear quickly after market bubbles burst.

Overall, air coins are a negative term for cryptocurrencies that seem attractive but lack lasting value. Proper market research and risk assessment are essential to avoid losses.
