Crypto by Category – AI, Web3, Gaming: Best Cheap Coins to Watch in 2025

In 2025, investors are shifting focus from hype-driven picks to sector-specific altcoins with real use cases. From meme coins under $0.01 to scalable AI, Web3, and gaming tokens, tracking crypto by category helps identify undervalued gems with stronger fundamentals and long-term growth potential.

AI Crypto Coins – Smart Contracts, Data & Automation

AI crypto coins power the intersection of blockchain and artificial intelligence, enabling use cases like predictive analytics, machine learning, data sharing, and smart contract automation. Leading projects in this space include FET (Fetch.ai), TAO (Bittensor), and GRT (The Graph)—each offering unique infrastructure for decentralized data and AI training.

Some Top Altcoins under $1 in the AI sector may offer early exposure to rapidly expanding ecosystems, making them attractive to investors seeking innovative, low-cost tokens.

For those looking to uncover hidden potential, it’s essential to learn how to find undervalued crypto in high-tech categories like AI—by tracking metrics such as developer activity, tokenomics, and real-world partnerships.

Web3 Coins – Decentralized Internet & Identity

Web3 represents the next evolution of the internet — where users own their data, identities, and digital assets. In crypto, Web3 tokens power platforms focused on decentralization, privacy, and user empowerment.

Popular projects include AR (Arweave) for decentralized storage, ENS (Ethereum Name Service) for blockchain-based identities, and MASK (Mask Network) for social data privacy.

Many Web3 protocols also introduce cheap DeFi coins with staking, allowing users to earn passive income while supporting decentralized infrastructure.

To identify long-term potential, investors should evaluate token utility, network adoption, and whether the project solves real-world Web3 challenges — all key indicators when assessing how to find undervalued crypto in this space.

Gaming Coins – Play-to-Earn & NFT Economies

Blockchain gaming has unlocked new economic models like play-to-earn (P2E) and NFT ownership, allowing players to earn real value through gameplay.

Leading gaming coins under $1 include AXS (Axie Infinity), GALA, and IMX (Immutable X) — all powering decentralized gaming platforms with active user bases and growing ecosystems.

To catch early trends and entry points, investors should track cheap crypto in real time, monitoring price, volume, and community engagement for gaming tokens.

As on-chain gaming continues to evolve, expect deeper integration of NFTs, cross-chain economies, and AI-driven gameplay, making gaming crypto a promising category for long-term growth.

Meme Coins vs Sector Coins: Speculation or Substance?

While meme coins under $0.01 thrive on hype, community memes, and viral marketing, sector-based tokens — such as AI, Web3, and gaming coins — are often backed by real-world utility and development roadmaps.

Meme coins like SHIB, PEPE, or DOG can deliver explosive short-term gains but carry higher volatility and fewer use cases. In contrast, sector coins often represent infrastructure, applications, or ecosystems that support the long-term growth of the blockchain space.

Smart investors often diversify between speculative meme coins and utility-focused assets to balance risk and potential upside. Knowing how to find undervalued crypto across both types can be a game-changer for building a resilient portfolio.

How to Research and Categorize Crypto Projects

To navigate the crowded altcoin landscape, it’s essential to know how to research and categorize crypto projects effectively. Tools like CoinMarketCap, TokenInsight, and DeFiLlama let you filter tokens by sector (AI, Web3, Gaming), market cap, volume, and on-chain activity.

Set up watchlists by category to track trends in real time — for example, following price movements of Top Altcoins under $1, or monitoring TVL and staking options for Cheap DeFi coins with staking.

This method also helps surface promising meme coins under $0.01 before they go viral, especially when combined with strategies on how to find undervalued crypto using developer activity, tokenomics, and community engagement.

Final Thoughts: Invest by Trend, Not Just Price

Chasing low-priced coins can be tempting, but without strong fundamentals, it’s a risky move. Whether you’re exploring Crypto by category – AI, Web3, Gaming or speculating on Meme Coins under $0.01, understanding the sector trend matters more than price alone.

Incorporating themes like Top Altcoins under $1 or Cheap DeFi coins with staking into your broader investment strategy helps diversify risk while targeting innovation.
