Decoding crypto slang: Examining origins and meaning of HODL, FOMO, FUD, and more

If you’ve spent even a few days in crypto, you’ve probably come across many crypto slangs.

At first glance, terms like FUD, FOMO, HODL, GM, or WAGMI might sound like random internet slang. In reality, though, these terms have become a language of their own, helping traders describe market sentiment and investor behavior.

More importantly, many of these popular crypto slangs didn’t come from Wall Street or textbooks. Instead, they came from memes, social media, and forum posts.

Here’s a look at some of the biggest crypto slangs and what they actually mean.

Market psychology crypto slangs – HODL, FOMO and FUD

HODL is arguably the most iconic crypto slang. The term originated in 2013 after a Bitcoin investor accidentally typed “I AM HODLING” instead of “I AM HOLDING” in a forum post during a market downturn. 

However, since then, these terms have grown beyond random internet slang.

Instead, these crypto slangs now act as a “bridge” between the social and technical sides of the market, helping traders and communities quickly describe emotions and narratives that often influence price movements. 

In this context, the three most widely used crypto slangs (HODL, FOMO, and FUD) all revolve around one thing: Market psychology.

Together, they explain how investors react during different phases of the market, whether it’s holding through uncertainty, chasing a rally, or reacting to fear-driven narratives. 

A real-time example can be seen in the chart above. 

The Crypto Fear & Greed Index remains in the “Fear” zone, a level that has historically marked the beginning of early FOMO (fear-of-missing-out) phases. When the market enters this phase, it suggests that investors are starting to view weakness as an opportunity.

Now, combining this with the ongoing macro FUD (fear, uncertainty, and doubt) from the Iran-US conflict, the fact that investors are still showing signs of FOMO highlights strong HODL conviction.

Instead of exiting, investors are holding through the volatility, allowing “buy-the-dip” FOMO to gradually build.

So, from a market psychology perspective, these crypto slangs (FUD, FOMO, and HODL) paint a clearer picture: Investors are choosing to hold while waiting for the right opportunity to enter.

If this trend continues, shifting sentiment could become a key driver for crypto’s next major move.

Community and culture slangs – DYOR, WAGMI, NGMI 

Unlike the crypto slangs mentioned above, these terms are less about market psychology and more about reflecting the culture and identity of the crypto community.

DYOR (Do Your Own Research), for example, reminds investors not to blindly follow online hype. Instead, it encourages users to research projects, understand the risks, and make their own investment decisions.

Meanwhile, WAGMI (We’re All Gonna Make It) gained popularity during the 2021 bull market, representing optimism and the belief that the broader crypto community will succeed over the long term.

On the other hand, NGMI (Not Gonna Make It) represents the opposite mindset. The term is often used to describe poor decisions, missed opportunities, or investors who fail to adapt to changing conditions.

In short, each crypto slang is more than internet memes. 

Instead, they provide a quick way to understand both market sentiment and community behavior. HODL, FOMO, and FUD explain how investors react to changing market conditions, while terms like GM, WAGMI, and DYOR reflect the culture that makes crypto different from traditional finance.

Together, these slangs bridge the gap between technical market analysis and the social narratives that continue to shape the crypto ecosystem.

Final Summary

• Crypto slangs like HODL, FOMO, and FUD reveal market psychology.
• Terms like DYOR, WAGMI, and NGMI highlight crypto’s unique community culture, bridging social narratives with market behavior.
