In today’s fast-paced financial markets, ETF trading has become one of the most popular and accessible investment strategies. Whether you're a traditional investor or a crypto enthusiast, understanding how ETF trading works can help you make smarter, more diversified investment decisions.

📈 What Is an ETF?

An ETF (Exchange-Traded Fund) is an investment fund that trades on stock exchanges, similar to individual stocks. Each ETF holds a collection of assets, such as:

  • Stocks (like the S&P 500)
  • Bonds
  • Commodities (like gold or oil)
  • Currencies
  • Cryptocurrencies (Bitcoin, Ethereum, etc.)

When you buy a share of an ETF, you're buying a fractional interest in the entire basket of assets. This makes ETFs a powerful tool for diversification, even for beginners.

💹 What Is ETF Trading?

ETF trading refers to the buying and selling of ETF shares on an exchange—just like you would with Apple or Tesla stock. The value of an ETF changes throughout the trading day, based on the underlying value of its assets.

ETF trading is commonly used for:

  • Portfolio diversification
  • Hedging strategies
  • Thematic investing (e.g., AI, clean energy, DeFi)
  • Speculating on short-term price movements

You can trade ETFs via your online brokerage, investment app, or even through certain retirement accounts (like IRAs).

🔄 How Does ETF Trading Work?

Here’s a simplified version of how ETF trading works:

  1. ETF Provider Creates the Fund
    A company like BlackRock or Fidelity creates an ETF that holds a specific basket of assets.

  2. ETF Listed on an Exchange
    The ETF is listed on public stock exchanges such as the NYSE or Nasdaq.

  3. Investors Buy and Sell Shares
    Investors trade ETF shares just like stocks—prices fluctuate throughout the day.

  4. Market Makers Maintain Liquidity
    Authorized participants ensure ETF prices closely match the value of the underlying assets (called the Net Asset Value or NAV).

🪙 What About Crypto ETFs?

In 2025, crypto ETFs have emerged as one of the fastest-growing segments of the ETF market.

Crypto ETFs allow investors to gain exposure to cryptocurrencies without owning the actual coins. These ETFs are regulated, secure, and accessible through traditional finance platforms.

There are two types:

  • Spot Crypto ETFs (hold actual crypto assets like Bitcoin or Ethereum)
  • Futures Crypto ETFs (track the price of crypto futures contracts)

Example: BlackRock’s iShares Bitcoin Trust (IBIT) is a spot Bitcoin ETF with billions in assets under management (AUM) in 2025.

✅ Benefits of ETF Trading

ETF trading offers unique advantages for both retail and institutional investors:

1. Diversification

Instead of buying dozens of individual stocks, ETFs offer broad exposure to sectors, themes, or markets in a single trade.

2. Liquidity

ETFs trade like stocks—buy or sell at any time during market hours. This makes them more flexible than traditional mutual funds.

3. Cost Efficiency

Many ETFs have low expense ratios, often under 0.25%. You avoid the high fees associated with actively managed funds.

4. Accessibility

Trade ETFs using any brokerage account. You don’t need to be an accredited investor or a crypto expert.

5. Tax Advantages

ETFs are generally more tax-efficient than mutual funds due to the in-kind creation/redemption process.

⚠️ Risks of ETF Trading

ETF trading, like all investing, carries risks:

1. Market Risk

ETF prices can go up or down depending on market conditions.

2. Liquidity Risk

Not all ETFs are highly traded. Low volume can lead to wide bid/ask spreads and slippage.

3. Tracking Error

Some ETFs fail to perfectly mirror their benchmark, especially futures-based crypto ETFs.

4. Sector Risk

Thematic ETFs (e.g., blockchain, AI) can be highly concentrated and volatile.

Fundamental Grade Crypto API: Real Crypto Fundamentals in One Score

Token Metrics Team
3

Most traders chase price action; Fundamental Grade Crypto API helps you see the business behind the token—community traction, tokenomics design, exchange presence, VC signals, and DeFi health—consolidated into one score you can query in code. In a few minutes, you’ll fetch Fundamental Grade, render it in your product, and ship a due-diligence UX that drives trust. Start by grabbing your key at the Get API Key page, Run Hello-TM to verify your first call, then Clone a Template to go live fast.

What You’ll Build in 2 Minutes

A minimal script to fetch Fundamental Grade from /v2/fundamental-grade for any symbol (e.g., BTC).

  • Optional curl to smoke-test your key in seconds.
  • A drop-in pattern to display the grade + key drivers in dashboards, screeners, and research tools.

Endpoints to consider next

  • /v2/tm-grade (technical/sentiment/momentum)
  • /v2/price-prediction (scenario planning)
  • /v2/resistance-support (risk levels)
  • /v2/quantmetrics (risk/return stats)

Why This Matters

Beyond price, toward quality. Markets are noisy—hype rises and fades. Fundamental Grade consolidates hard-to-track signals (community growth, token distribution, liquidity venues, investor quality, DeFi integrations) into a clear, comparable score. You get a fast “is this worth time and capital?” answer for screening, allocation, and monitoring.

Build trust into your product. Whether you run an investor terminal, exchange research tab, or a portfolio tool, Token Metrics discovery helps users justify positions. Pair it with TM Grade or Quantmetrics for a balanced picture: what to buy (fundamentals) and when to act (signals/levels).

Where to Find

The Fundamental Grade is easily accessible in the top right of the API Reference. Grab the cURL request for seamless access!

Ready to build?

  • Run Hello-TM — verify your first successful call.
  • Clone a Template — deploy a screener or token page today.

Watch the demo: VIDEO_URL_HERE. Compare plans: Scale confidently with API plans.

FAQs

1) What does the Fundamental Grade API return?

A JSON payload with the overall score/grade plus component scores (e.g., community, tokenomics, exchange presence, VC backing, DeFi health) and timestamps. Use the overall grade for ranking and component scores for explanations.

2) How fast is the endpoint? Do you publish SLOs?

The API is engineered for predictable latency. For high-traffic dashboards, add short-TTL caching and batch requests; for alerts, use jobs/webhooks to minimize round-trips.

3) Can I combine Fundamental Grade with TM Grade or signals?

Yes. A common pattern is Fundamental Grade for quality filter + TM Grade for technical/sentiment context + Trading Signals for timing and Support/Resistance for risk placement.

4) How “accurate” is the grade?

It’s an opinionated synthesis of multiple inputs—not financial advice. Historical studies can inform usage, but past performance doesn’t guarantee future results. Always layer risk management and testing.

5) Do you offer SDKs and examples?

You can use REST directly (see JS/Python above). The docs include quickstarts, Postman, and ready-to-clone templates—start with Run Hello-TM.

6) Polling vs webhooks for fundamentals updates?

For UI pages, cached polling works well. For event-style notifications (upgrades/downgrades), prefer webhooks or scheduled jobs to avoid spiky traffic.

7) What about pricing, limits, and enterprise SLAs?

Begin free and scale as you grow. See API plans for allowances; enterprise SLAs and support are available—contact us.

How It Works (Under the Hood)

Fundamental Grade aggregates multiple project-quality signals into a normalized score and label (e.g., Strong / Average / Weak). Typical sub-signals include:

  • Community: momentum across channels (dev activity/user traction signals where applicable).
  • Tokenomics: supply schedule, distribution, unlock dynamics, incentives.
  • Exchange Presence: venue coverage, depth/liquidity proxies.
  • VC/Investor Signals: quality/durability of backing and ecosystem support.
  • DeFi Health: integrations, TVL context, composability footprint.

At query time, you call /v2/fundamental-grade with a symbol; responses include the overall score plus component scores you can visualize. For dashboards with many assets, batch fetches and short-TTL caching keep pages responsive. If you push alerts (e.g., “Fundamental Grade upgraded”), prefer webhooks or queued jobs to avoid hammering the API.

Production Checklist

  • Rate limits: Know plan caps; add client throttling and request queues.
  • Retries/backoff: Exponential backoff + jitter; surface actionable error messages.
  • Idempotency: Prevent duplicate downstream actions on retried calls.
  • Caching: Use memory/Redis/KV with short TTLs; pre-warm popular symbols.
  • Webhooks & jobs: For alerts, use signed webhooks or scheduled jobs; log delivery outcomes.
  • Pagination/Bulk: When covering many tokens, paginate or process in batches.
  • Error catalog: Map 4xx/5xx to user-visible fixes; log request IDs.
  • Observability: Track p95/p99 and error rate per endpoint; alert on spikes.
  • Security: Keep API keys in secrets managers; rotate regularly.

Use Cases & Patterns

  • Screener Maker: Rank tokens by Fundamental Grade, filter by market cap/sector, and add “rising fundamentals” badges for discovery.
  • Dashboard Builder: On each token page, show the headline grade with a component chart; link to methodology for transparency.
  • Research & PM Tools: Flag downgrades/upgrades to prompt re-evaluation; attach notes to component changes (e.g., DeFi health drop).
  • Allocator / Risk: Require a minimum Fundamental Grade before inclusion; rebalance only when grade crosses thresholds.
  • Community/Discord: Post weekly upgrades as digest messages with links back to your app.

Next Steps

  • Get API Key — generate a key and start free.
  • Run Hello-TM — verify your first successful call.
  • Clone a Template — deploy a screener or token page today.
  • Watch the demo: VIDEO_URL_HERE

It’s designed for hands-off allocators who want disciplined exposure and for active traders who want a core that adapts to regimes—without guesswork or endless rebalancing.

Join the waitlist to be first to trade TM Global 100.

Why Indices Matter in October 2025

Search intent right now: investors want credible, rules-based crypto exposure that can participate in upside while reducing drawdown pain. A crypto index is a basket of assets selected and maintained by rules—so you avoid one-off bets and constant manual rebalancing.

With liquidity rotating quickly across sectors, weekly rebalancing helps maintain alignment with current market-cap leaders, while regime switching provides a disciplined, pre-defined response to bearish conditions. The result is a clear, consistent process that removes emotional decision-making and operational drag.

Definition

A crypto index is a rules-based basket of digital assets that’s constructed, weighted, and rebalanced on a set schedule.

  • Regime switching: Bullish: Hold the top-100 crypto assets by market cap.
  • Bearish: Exit all positions into stablecoins and wait for a new bullish signal.
  • Weekly rebalancing: Reflects updated rankings and weights across the market-cap universe.
  • Transparency: Strategy modal shows methodology and thresholds; Gauge → Holdings Treemap → Transactions Log make every change visible.

What you’ll see on launch: Price tile, gauge (“rebalances weekly”), 100 tokens, one-click Buy Index flow, and a 90-second checkout via embedded wallet.‍See the strategy and rules.

Benefits at a Glance (Why This Beats DIY)

  • Lower execution drag: One click vs. dozens of individual orders that can add slippage.
  • Stay current: Weekly rebalances help you capture market-cap changes without constant monitoring.

FAQs

1) What is a TM Global 100 index?

It’s a rules-based crypto index that holds the top 100 assets by market cap in bullish regimes and moves to stablecoins in bearish regimes. It rebalances weekly and shows transparent holdings and transactions.

2) How often does the index rebalance?

Weekly, with additional full-portfolio switches when the market regime changes.

3) What triggers the move to stablecoins?

A proprietary market signal. When bearish, the index exits all token positions into stablecoins and waits for a bullish re-entry signal.

4) Can I fund with USDC or fiat?

At launch, funding and settlement options surface based on the embedded wallet and supported chains. USDC payouts are supported for selling; additional entry options may be introduced later.

5) Is the wallet custodial?

No. The Embedded Wallet is self-custodial—you control your funds while using a streamlined, on-chain checkout.

6) How are fees shown?

Before you confirm, the Buy flow shows estimated gas, platform fee, maximum slippage, and the minimum expected value.

7) How do I join the waitlist?

Go to the Token Metrics Indices hub or the TM Global 100 strategy page and submit your email. We’ll notify you the moment trading opens.

Security, Risk & Transparency

  • Self-custody: Embedded smart wallet; you hold the keys.
  • 2FA & session hygiene: Use strong auth practices for your TM account.
  • Fee clarity: Gas, platform fee, and slippage are displayed before you confirm.
  • Auditability: Holdings, treemap, and transactions log are always visible.
  • Model limits: Regime logic can be wrong, and markets can gap; rules reduce discretion—not risk.
  • Regional availability: Product surfaces may vary by region as we expand.

Crypto is volatile and can lose value. Past performance is not indicative of future results. This article is for research/education, not financial advice.

Conclusion

If you want a disciplined, rules-based core that adapts to market regimes, Token Metrics Global 100 is built for you. Weekly rebalances, transparent holdings, and one-click buy remove operational friction so you can focus on your strategy.
