HODL, FOMO and DYOR: a guide to crypto community slang

Crypto discussions often mix English abbreviations with internet slang in a single sentence. Knowing the meanings helps you follow the conversation, but jokes and rallying cries should not become reasons to invest.

Common English abbreviations

  • HODL: Holding an asset instead of selling it. The expression spread from a misspelling of HOLD in a 2013 Bitcoin forum post.
  • FOMO: Fear Of Missing Out—the anxious feeling that everyone else will catch an opportunity you miss.
  • FUD: Fear, Uncertainty, Doubt. It describes claims that create unease or suspicion. Calling something FUD does not prove it is false.
  • DYOR: Do Your Own Research. A reminder to check the evidence yourself; adding it does not verify the author's claims.
  • NFA: Not Financial Advice. This phrase alone does not automatically establish the reliability of a post or the author's responsibility.
  • ATH / ATL: All-time high and all-time low under a given dataset. Check the exchange and quotation currency used.

Expressions common in Korean communities

  • Gajeua (가즈아): A rallying cry, roughly “Let's go!”, often expressing hopes for rising prices.
  • Mullyeotda (물렸다): Being stuck with a loss after the price falls below your purchase price.
  • Multagi (물타기): Buying more after a price drop to lower your average entry price. Your amount invested and potential loss can also increase.
  • Bull market / falling market (불장 / 하락장): Descriptions of a broadly rising or falling market mood, without a single clear official test.
  • Whale (고래): A holder of a large amount of assets. One large wallet does not necessarily represent one individual.
  • Rug pull (러그풀): Fraudulent conduct that harms users, such as operators withdrawing funds or liquidity. A sharp price fall alone does not establish the cause.

What to check when reading a post

Claims like “a whale bought” or “it's definitely going up” often mix facts with hopes. Look for verifiable evidence, such as a transaction hash or an official notice. Check whether the writer holds the asset or benefits from referral rewards.

Understanding a term is different from agreeing with what someone says. If a post pressures you to act quickly, checking the original source and its date matters more than looking up an abbreviation.
