Top 5 gem coins to watch in December 2025

By: WEEX|2025/12/10 17:30:00

The crypto market at the end of 2025 is witnessing many potential projects (“gem coins”) across diverse sectors such as GameFi, DeFi, Layer 2, AI, and real-world assets (RWA). Below are the gem coins to watch in December 2025, selected based on high growth potential (in terms of technology, products, and team), backing from reputable funds, and especially important events/updates in December 2025 (mainnet launches, testnets, upgrades, or major partnerships, etc.).

Talus – A unique AI competitive gaming platform (GameFi + AI)

Talus is a GameFi platform that incorporates artificial intelligence, where AI “agents” compete against each other and users can predict the outcomes of these matches. This creates a novel form of “AI esports” on the blockchain, known as the Agent vs Agent (AvA) model. For example, two AIs can play chess or a strategy game, and users bet on which AI will win; if the prediction is correct, they receive a reward. This concept turns AI matches into a public entertainment prediction market, with transparency guaranteed on-chain.

Talus is gaining attention thanks to its PredictionAI technology – a combination of AI agents and prediction markets – built on the Sui Network. The project has raised over $10 million in seed funding led by Polychain Capital, with participation from the Sui Foundation and Walrus Protocol. Talus has a testnet (the Idol.fun platform) running AvA matches to engage the community, and plans to launch AvA Markets on mainnet in Q1 2026. The fact that a GameFi project combining AI has received investment from a major fund like Polychain highlights its growth potential, making Talus a “gem coin to watch” in the blockchain gaming sector at the end of this year.

Limitless – Short-term crypto price prediction market (DeFi)

Limitless is a DeFi prediction market platform built on the Base blockchain (Coinbase's scaling chain). The difference with Limitless is its focus on predicting short-term price fluctuations of crypto assets (and even traditional stocks), rather than political or sports events like other platforms. Users can bet on the price direction of BTC, ETH, or stocks within a timeframe of a few minutes, hours, or days and earn a profit if their prediction is correct. For example, you can predict “BTC price will exceed $40,000 in the next 24 hours”; if it happens by the deadline, you receive a reward from the betting pool. Conversely, if you are wrong, you lose your stake. This approach turns short-term trading into a simple prediction game that is beginner-friendly (with an intuitive mobile interface), creating opportunities for everyone to “trade” without complex technical knowledge.

Limitless has attracted significant attention from the investment community. The project has raised $7 million (with $4 million in the most recent strategic round), led by Coinbase Ventures, with participation from 1confirmation, Collider, Node Capital, and even former BitMEX CEO Arthur Hayes as an advisor. The fact that a new project is backed by Coinbase Ventures and has achieved a trading volume of over $250 million even before launching its token shows significant growth potential. Limitless has announced plans for an LMTS token airdrop for active users, and the TGE (Token Generation Event) is expected to take place at the end of 2025. By meeting both the criteria of unique technology and backing from major funds, Limitless deserves to be a gem coin to watch this December.

Aztec Network – Private Layer 2 solution for Ethereum (Layer 2)

Aztec Network is a Layer 2 (L2) project on Ethereum focused on privacy. Simply put, Aztec helps you perform transactions or interact with smart contracts on Ethereum while protecting your secrets – transaction content is encrypted, and only the sender and receiver know the details, similar to how Zcash secures transactions. This is very friendly for those who want financial privacy, as currently, all Ethereum transactions are public on the blockchain. Aztec achieves this by combining zero-knowledge (ZK) technology and advanced Fully Homomorphic Encryption (FHE).

Key milestone: In December 2025, Aztec launched its mainnet (“Ignition chain”) – becoming the first fully decentralized Ethereum L2 network (not controlled by a single company). They even “took off the training wheels” by relinquishing control of the rollup contract, not allowing the team and investors to operate nodes for the first 12 months, ensuring the network is community-operated from the start. Along with that, Aztec implemented a staking mechanism that allows users to stake AZTEC tokens to participate in consensus and receive block rewards.

Especially in December 2025, Aztec is holding a community token sale: after a whitelist round for the community (ending December 1), it will be sold publicly from December 2–6 using a continuous auction model. A total of ~15% of the supply (1.547 billion AZTEC) is being sold, with a floor price of approximately $0.03/token (a diluted valuation of approximately $310 million). The project previously raised $100 million in its Series B round and is backed by a series of big names: Vitalik Buterin, Coinbase Ventures, Paradigm, ConsenSys, Andreessen Horowitz (a16z), HashKey Capital... With breakthrough privacy technology and major events right in December (mainnet + token sale), Aztec Network is emerging as a gem coin to watch in December in the Layer 2 scaling solutions space.

Bittensor (TAO) – Decentralized AI network with a halving event (AI)

Bittensor is a unique project that combines blockchain and AI, creating a decentralized network for machine learning. You can think of Bittensor as the “Bitcoin of the AI sector”: instead of mining coins with computing power to secure the network (like Bitcoin), Bittensor participants contribute computing resources and train AI models. The Bittensor network encourages developers and AI experts to bring their models to build an open-network super AI, in exchange for which they receive TAO tokens as rewards. This helps decentralize AI power, without depending on a few large corporations – which is very meaningful in the context where traditional AI is controlled by a small number of large companies.

Bittensor's TAO token has an economic mechanism similar to Bitcoin, with a limited supply of 21 million and a halving program every 4 years. December 2025 marks the first halving of TAO, expected to take place around December 14, 2025, when the block reward decreases from 1 TAO to 0.5 TAO per block – meaning a reduction in reward inflation from ~7,200 TAO/day to ~3,600 TAO/day. This halving event creates a supply shock similar to Bitcoin, which could drive prices up if demand remains steady or increases. In fact, demand for TAO is trending upward: Bittensor is attracting more and more users and institutional investment (Grayscale has even established a Bittensor trust for institutional investors). Some venture capital funds and publicly traded companies (such as Synaptogenix, Oblong) have also purchased TAO as a strategic asset. With a novel technological foundation in the AI sector and an important deflationary event in December, Bittensor (TAO) is emerging as a gem coin to watch for both the crypto investment community and the AI community.

Ondo Finance – Tokenized real-world assets, bridging DeFi and traditional markets (RWA)

Ondo Finance is one of the pioneering projects in the RWA (Real-World Assets) trend – tokenizing real-world assets. Ondo focuses on bringing traditional financial assets such as US Treasury bonds, stocks, and ETFs onto the blockchain in the form of tokens, allowing crypto investors to easily access safe assets or the stock market right within the DeFi space. For example, instead of buying US Treasury bonds through a bank, you can buy tokens representing those bonds on Ondo and receive similar yields, while still being able to trade 24/7 and use these tokens as collateral in DeFi. Ondo acts as a bridge, complying with regulations to ensure that RWA tokens are 100% backed by real-world assets.

In December 2025, Ondo recorded important legal milestones: The US Securities and Exchange Commission (SEC) has officially closed its investigation into Ondo without any charges of violations. The investigation, which lasted from 2024, aimed to determine whether Ondo's tokenization of bonds and offering of ONDO tokens complied with securities laws. The SEC's conclusion of the investigation without charges is seen as a turning point: US regulators are beginning to support the trend of securities tokenization, paving the way for RWA to develop more strongly. At the same time, Ondo has also been licensed by the Liechtenstein financial authority (EU passport) to provide stock and ETF token services across Europe. Thanks to this license, Ondo can reach up to 500 million investors in 30 countries within the European Economic Area – a major step forward in bringing traditional assets onto the blockchain in the international market.

Currently, Ondo prides itself on being the largest stock and ETF tokenization platform by asset value, with >315 million USD in tokenized assets locked on the platform and over 1 billion USD in trading volume since its launch. The project has also previously attracted capital from well-known funds (including Founders Fund, Pantera Capital in previous rounds). With a solid foundation and approval from both US and EU regulators in December, Ondo Finance is building great confidence in the potential of RWA – deserving to be on this list of gem coins to watch in December for investors interested in the intersection of DeFi and traditional finance.
