Tool Lab: Categories + Narrative Tagging

You're Not Diversified Just Because You Own 8 Tokens

Vikram owned BTC, ETH, SOL, AVAX, MATIC, ARB, OP, and ATOM. Eight different tokens. He thought he was well-diversified. Then the crypto market corrected 30% in a week, and all eight dropped between 25% and 45%.

Why? Because seven of his eight holdings were in the same category: Layer 1 and Layer 2 infrastructure. When that narrative fell out of favour, everything in it dropped together. Owning eight correlated assets isn't diversification — it's concentration with extra steps.

What Are Narratives in Crypto?

In the stock market, you have sectors: IT, banking, pharma, FMCG. When one sector falls, others might hold steady. Crypto has something similar called narratives — thematic categories that groups of tokens belong to.

Common narratives include:

• Layer 1s — Base blockchains (ETH, SOL, AVAX, SUI)
• Layer 2s — Scaling solutions (ARB, OP, MATIC, BASE)
• DeFi — Decentralised finance protocols (AAVE, UNI, CRV)
• AI/Compute — Decentralised AI and computation (RNDR, FET, TAO)
• Gaming/Metaverse — Blockchain games (AXS, IMX, GALA)
• Real World Assets (RWA) — Tokenised real-world assets (ONDO, MKR)
• Memecoins — Community-driven tokens (DOGE, SHIB, PEPE)
• Infrastructure — Oracles, storage, bridges (LINK, FIL, ATOM)

Tokens within the same narrative tend to move together. When AI tokens are hot, most AI tokens pump. When the narrative cools, they all drop — regardless of individual fundamentals.

How to Find Categories on CMC

CoinMarketCap has a Categories section that groups tokens by narrative. Every token page also shows tags — clickable labels like "DeFi," "Layer 1," "AI," "Gaming."

To use this:

1. Open any token on CMC
2. Look for the tags section (usually near the top or under the coin info)
3. Click a tag to see all tokens in that category
4. Note which categories your holdings fall into

If 70% of your portfolio is in one category, you're not diversified. You're making a concentrated bet on one narrative.

Building a Narrative Map of Your Portfolio

Take every token you own and write down its primary narrative:

Now look at the distribution. If one narrative dominates, you know exactly where your concentration risk is. This isn't about selling everything — it's about knowing what bet you're actually making.

Using Narratives for Research

Narratives also help you find new projects to research:

• If you believe AI and crypto will converge, browse the AI category on CMC to find the top tokens by market cap in that space
• If you think real-world asset tokenisation will grow, look at the RWA category
• If a narrative is heating up (you see multiple tokens pumping), check the category page to understand what's driving it

The key insight: narratives cycle. DeFi Summer 2020, NFTs in 2021, AI tokens in 2024 — what's hot rotates. Understanding this helps you avoid chasing a narrative after it's already peaked.

Quick Recap

• Owning multiple tokens in the same category isn't diversification
• Crypto narratives (L1, DeFi, AI, Gaming, etc.) behave like stock market sectors
• Tokens within a narrative are highly correlated — they pump and dump together
• Use CMC's categories and tags to map your portfolio by narrative
• If one narrative dominates your portfolio, you have concentration risk
• Narratives cycle — today's hot sector is tomorrow's underperformer

Checklist

• Map every token in your watchlist to its primary narrative/category
• Check if more than 50% of your holdings fall into a single narrative
• Browse at least 2 CMC categories you haven't explored before
• Identify which narrative is currently "hot" — and check if you're late to it

Common Mistakes

• Thinking you're diversified because you own many different tokens — narrative correlation matters more than token count
• Chasing a narrative after it's already pumped 300% — the easy gains are over
• Ignoring narrative rotation — holding last cycle's winners while this cycle's narratives pass you by
• Not tagging your watchlist tokens by category, making it impossible to spot overconcentration
