Crypto conversations mix technical language, jokes and internet shorthand. Knowing the vocabulary can help you understand a post, but slang should never replace evidence. A confident phrase may describe a mood, not a fact about a project.
Market emotions and behavior
HODL means holding through volatility. FOMO is fear of missing out, while FUD means fear, uncertainty and doubt. Diamond hands praises someone who refuses to sell; paper hands criticizes an early exit. To the moon or mooning predicts a dramatic rise. Rekt means suffering a severe loss.
Ape in describes buying quickly with little research. Degen, short for degenerate, is often used jokingly for highly speculative behavior. Bag holder describes someone left holding an asset after a major fall. These words can normalize risk, so pause before copying the behavior they celebrate.
Community language
WAGMI means “we are all going to make it,” while NGMI means “not going to make it.” GM is simply “good morning,” and ser is an intentionally altered “sir.” IYKYK means “if you know, you know.” These expressions build group identity but prove nothing about value or safety.
Research and promotion
DYOR means “do your own research.” NFA means “not financial advice,” but writing NFA does not make a misleading claim harmless. A shill aggressively promotes an asset, sometimes without revealing a financial interest. Always look for evidence and conflicts of interest.

Coins, networks and scams
A whale holds enough of an asset to potentially influence a market. A shitcoin is a dismissive label for a coin seen as low quality. Altseason describes a period when many non-Bitcoin assets outperform Bitcoin. Gas is the fee-related measure for blockchain computation. Sats are satoshis, the smallest Bitcoin unit. A rug pull is a scam where insiders remove value or use hidden control against buyers.
Look up a term before reacting
The Crypto Slang Decoder lets you search all 24 terms, open a plain-English definition and read a simple example. When a post uses slang to create urgency, slow down and check the underlying claim separately.
Context matters too. The same word can be playful between friends, promotional in an influencer post or critical in a risk discussion. Read the full sentence, identify who benefits from the message and confirm any factual claim through independent sources. Understanding the vocabulary helps you follow the conversation; it does not make a token, trade or account trustworthy.
