  • Pulls live data from Token Metrics (price, signal, grade)
  • Evaluates the signal (e.g., bullish)
  • Executes a buy trade if the signal is positive

The contract is compiled in Remix IDE, connected via MetaMask (on testnet), and deployed using testnet ETH and LINK tokens.

After deployment, you’ll receive a contract address that can be added to your Chainlink subscription.

4. Create a Chainlink Subscription

To fund your contract for data requests:

  1. Go to the Chainlink portal
  2. Create a new subscription (testnet or mainnet)
  3. Fund it with some LINK
  4. Add your deployed smart contract as a consumer

This allows your contract to make external data calls using Chainlink’s decentralized oracle network.

5. Run a Script to Invoke Real-Time Token Metrics Data

Using the provided JavaScript scripts, you can interact with the smart contract and test data flow:

  • Check the bot’s active status
  • Retrieve token price, trading signal, and grade
  • See how the smart contract responds to live market conditions

In the demo, the bot received a bullish signal, saw that the grade was high, and executed a buy trade accordingly. This logic can be expanded into full-scale trading strategies, rebalancing rules, or even on-chain governance triggers.

 Introduction: The High Stakes of Moonshot Crypto

Moonshot investing in crypto is a double-edged sword. On one side, you have tokens that can 10x, 50x, or even 100x your portfolio. On the other side? Complete capital loss. While these asymmetric bets can lead to explosive profits, they also carry extreme risk—especially for uninformed or impulsive investors.

This guide will break down the risk landscape of moonshots: what makes them so volatile, common pitfalls to avoid, risk management strategies, and how tools like Token Metrics help reduce blind spots when betting on the next big thing.

What Makes Moonshot Investments So Risky?

Moonshots live in the outer rim of the crypto market. They are typically:

  • Low market cap (<$20M)
  • Light on liquidity
  • Not listed on major exchanges
  • Lacking product-market fit
  • Speculative or narrative-driven

These factors create an environment where price moves fast—but fundamentals are often thin. You're betting more on potential than proof.

Common Risks in Moonshot Investing

‍

‍

You must assume every moonshot has some of these risk factors — and plan accordingly.

Risk Profile: Moonshots vs. Blue Chips

‍

‍

Moonshots = high variance. Don’t treat them like stable assets.

🛡️ How to Manage Moonshot Risk (and Stay Sane)

  1. Use Proper Position Sizing
    Never allocate more than 1–3% of your total portfolio to a single moonshot.

  2. Diversify Your Moonshots
    Build a “moonshot basket” of 5–10 different bets across categories (AI, DePIN, L1s, Meme, etc).

  3. Set Clear Entry and Exit Plans
    Know your take-profit and stop-loss targets before entering.

  4. Track Vesting & Unlock Schedules
    Use tools like Token Unlocks to avoid buying before big token dumps.

  5. Don’t Fall in Love With Your Bags
    Stay objective. Exit when the narrative fades or fundamentals change.

đź§Ş Risk Evaluation Checklist

If you answer “no” to 2 or more of these, tread cautiously.

How Token Metrics Minimizes Risk Exposure

Token Metrics helps de-risk moonshots by analyzing over 80+ data points using AI and quant models:

  • Risk-adjusted momentum scores
  • Tokenomics evaluations
  • On-chain behavior analysis
  • Contract audit status
  • Community health signals
  • Bullish/Bearish alerts based on AI

You get a comprehensive view of upside and downside before making a decision.

Mental Models for Risky Investing

  • “Play with house money” – Take profits early and only risk profits.
  • “Barbell strategy” – Majority in stable assets, small % in high-risk/high-reward.
  • “Expected Value (EV)” – Even if 8/10 fail, 1 big win covers losses.
  • “Don’t chase losses” – Accept failures quickly and move on.

Moonshot investing is mental warfare. Stick to frameworks, not FOMO.

Final Thoughts: Risk is Inevitable — Manage It, Don’t Fear It

The path to 100x gains in crypto will always be riddled with landmines. But risk isn’t inherently bad — it’s the price of asymmetric upside. The real danger is unmanaged risk, impulsive decisions, and poor research.

With the right approach, the right tools, and a clear head, moonshot investing can be one of the most rewarding strategies in crypto.

Just remember: You only need to be right once.

Are Moonshots Only Meme Coins?

Token Metrics Team

Introduction: The Meme Coin Myth

When most people think “moonshot” in crypto, they think of meme coins like Dogecoin, Shiba Inu, or Pepe — volatile, viral, and often with no utility. While it’s true that meme coins have historically delivered explosive returns, they’re just one type of moonshot. In reality, some of the best moonshots are deeply technical projects with innovative real-world use cases.

In this blog, we’ll explore why moonshots go far beyond memes, the other types of high-potential assets you should be watching, and how to distinguish hype from substance in your moonshot hunt.

Why Meme Coins Became the Face of Moonshots

Meme coins dominate headlines and retail attention for good reason:

  • Low entry barriers – Often priced at fractions of a cent
  • Viral marketing – Driven by memes, humor, and community hype
  • Explosive gains – SHIB, DOGE, and PEPE all had 1,000x+ runs
  • Community-driven – Holders often act as evangelists

Because of these qualities, meme coins are often perceived as the only moonshots. But perception doesn’t equal reality.

The Reality: Many Moonshots Are Utility-Driven

Some of the most successful moonshot investments didn’t begin as memes — they were innovative, under-the-radar projects that grew into billion-dollar ecosystems:

None of these were memes — they were tech-focused moonshots.

Categories of Non-Meme Moonshots

Here are several non-meme sectors producing moonshot-level gains:

  1. AI Coins – e.g., Fetch.ai, Render, Akash
  2. DePIN (Decentralized Physical Infrastructure) – e.g., Helium, IoTeX
  3. RWAs (Real-World Assets) – e.g., Centrifuge, Goldfinch
  4. L2 & Interoperability – e.g., Starknet, Hyperlane, Axelar
  5. Privacy Coins – e.g., Namada, Secret Network
  6. Early-stage L1s – e.g., SEI, Monad

These projects combine visionary ideas with real-world applicability — and many began as stealth moonshots before going mainstream.

How to Spot Utility-Based Moonshots Early

Look for:

  • Unique narrative fit – Aligns with hot macro themes (AI, DeFi 2.0, Web3 infra)
  • Underexposed – Not yet listed on major CEXs or hyped by influencers
  • Backed by smart money – VC involvement or known crypto angels
  • Product roadmap – Testnet/Mainnet imminent or newly launched
  • Active GitHub or whitepaper – Real builders, not marketers

Meme coins may be powered by emotion — but utility moonshots are powered by execution.

Token Metrics Helps Spot Both Meme & Utility Moonshots

Token Metrics doesn’t just chase hype — it grades thousands of tokens using 80+ data points including:

  • Momentum and price trends
  • Community sentiment and buzz
  • GitHub commits and developer activity
  • Market cap ranking
  • AI-generated bull/bear signals
  • Smart contract risk analysis

This means you can discover both emerging meme coins and tech-driven moonshots based on real metrics — not just Twitter noise.

Can Meme Coins Still Be Valid Moonshots?

Yes — but they should be treated like short-term plays with proper risk management. When timed right (early launch, CEX rumor, meme trend), meme coins can 10x fast. But unlike utility tokens, meme coins often lack long-term sustainability unless they evolve (like DogeX or SHIB ecosystem).

Use tools like Token Metrics AI Signals to time entries and exits.

⚠️ Avoiding the Meme Coin Traps

‍

Don’t confuse “meme” with “momentum.” Use data.

Conclusion: The Smart Moonshot Portfolio is Diversified

If your moonshot portfolio is 100% meme coins, you're gambling. If it’s 100% early L1s with no traction, you may be stuck waiting years. Smart investors build a balanced basket that includes:

  • Memes with momentum
  • Mid-cap undervalued alts
  • Undiscovered AI, RWA, and DePIN gems
  • Fundamental plays with strong tokenomics

Meme coins are just one path to the moon — don’t miss the others.
