暗号用語入門：初心者脱却のためのチートシート

FOMO got you scrolling Discord at 3am? Keep seeing HODL and moon in every chat? Here’s the real talk—if you don’t speak crypto vernacular, you’re basically playing poker blindfolded. Let’s decode the 50 most toxic, genius, and absolutely essential terms flying around right now.

The Culture Codes (What People Actually Say)

FOMO = Fear of Missing Out. Watching others moon while you’re holding stables? That panic-buy energy.

HODL = A typo that became a religion. Means hold your coins long-term like your life depends on it (or don’t sell in a bear market, basically).

GM = Good morning. Just crypto Twitter saying hello. No deeper meaning.

Moon/Mooning = Price exploding. Sky’s the limit mentality.

Rekt = Destroyed. Lost bigly. Account in the negatives.

Shill = Hard-pushing a project to get others to buy so you can dump.

FUD = Fear, Uncertainty, Doubt. The pessimist energy designed to tank prices.

Whale = Someone holding millions. They move, market moves.

Pump and Dump = Classic market manipulation: buy low, hype it, sell when normies FOMO in.

DYOR = Do Your Own Research. Essentially “I’m not a financial advisor, bro.”

Rug Pull = Dev takes the money and vanishes. Game over.

ATH/ATL = All-Time High/Low. Your entry point regrets summed up.

LFG = Let’s Fucking Go. Self-explanatory hype meter.

The Tech Stack (What Actually Matters)

DeFi = Decentralized Finance. Banking without banks. It’s the whole rebel movement.

Smart Contracts = Self-executing code. The digital handshake that powers everything.

Staking = Lock your coins, earn rewards. Your passive income if the chain doesn’t die.

Mining = Solve equations, get paid in crypto. Proof of Work’s biggest energy consumer.

Liquidity Pools = Users deposit tokens so traders can swap. You earn fees if whales don’t rug you.

Yield Farming = Put tokens in DeFi protocols, chase APY%. It’s gambling with extra steps.

Oracle = External data piped into smart contracts. The bridge between blockchain and reality.

Airdrop = Free tokens. Community building or exit scam preview.

DEX vs CEX = Decentralized exchange (no KYC, you hold keys) vs Centralized exchange (easier but risky if hacked).

Layer 1 vs Layer 2 = Bitcoin/Ethereum (base chain) vs Arbitrum/Optimism (faster, cheaper settlements).

TVL = Total Value Locked. How much money is actually in a DeFi protocol. Higher = more adoption or more risk concentration.

Gas Fees = Cost to execute transactions on Ethereum. Gwei is the unit. Can be brutal in bull markets.

Cross-chain = Tokens moving between different blockchains. Interoperability is the holy grail.

Hard Fork vs Soft Fork = Hard fork splits the chain (Ethereum going proof-of-stake). Soft fork is backward compatible (minor tweaks).

Hash Rate = Network computing power. Higher = more secure but also more electricity.

Satoshi/SATS = Bitcoin’s smallest unit. 100M sats = 1 BTC.

Seed Phrase = Your password to everything. Lose this, lose your coins. Forever.

Private/Public Keys = Private = password (NEVER share). Public = your address (safe to publish).

KYC/AML = Know Your Customer / Anti-Money Laundering. The compliance tax on crypto.

DAO = Decentralized Autonomous Organization. Community-run entities with no CEO.

NFT = Non-Fungible Token. Digital ownership proof. Art, collectibles, JPEGs people paid 6 figures for.

ICO = Initial Coin Offering. The OG token sale model (90% scams, 10% actual projects).

Soft/Hard Fork = Network upgrades. Hard forks can cause chain splits if not everyone updates.

Block Reward = How much crypto miners/validators earn per block. Halving events matter here.

CBDC = Central Bank Digital Currency. Governments want to track you more closely.

APY = Annual Percentage Yield. The return rate you’re chasing (sometimes delivered, often not).

The Coin Types (Know What You’re Actually Buying)

Altcoins = Everything that isn’t Bitcoin. Ethereum, Solana, Cardano, etc. They either improve on Bitcoin or do something completely different.

Shitcoins = Altcoins with zero utility, no roadmap, and vibes only. High-risk gambling disguised as investment.

Memecoins = Born from internet jokes. Dogecoin is the OG godfather here. SHIB, PEPE, DOGE clones everywhere. Community-driven hype machines.

Golden Dog = Memecoin that actually mooned 100x+. Still a shitcoin technically, but now it’s famous.

Earthcoin/Stagflation Coin = Regular memecoins that never made it. Warnings on what not to buy.

Airtcoin = Project with zero backing, pure speculation, likely a rug pull waiting to happen. Exists only in hype, collapses when attention moves.

The Real Talk

Knowing the lingo means you can at least identify which circles you’re in and what’s actually happening. Altcoins come with different consensuses (Ethereum went Proof of Stake, Dogecoin is still Proof of Work), different speeds, different communities. Some have actual tech (Ethereum’s smart contracts changed the game). Others are just repackaged ideas.

Memecoins are fascinating—they prove crypto isn’t just finance, it’s culture. But they’re also where fortunes die. Dogecoin worked because Elon memed it and people started accepting it. SHIB tried the same formula. Most don’t survive past their initial hype.

Aircoin is basically the crypto equivalent of buying a lottery ticket someone’s already scratched and thrown away.

Bottom line: Understand the mechanics before you’re in them. Research the team, check TVL for DeFi plays, verify the roadmap, and never put money in anything you can’t explain to a friend. The slang is just the wrapping paper—the actual project underneath is what matters.

Now stop scrolling and DYOR.
