If you're searching for the best altcoins to buy now, 2025 is shaping up to be a pivotal year. Emerging trends like Layer-2 scaling, real-world asset (RWA) tokenization, and AI integration are driving the next wave of crypto innovation.

Projects such as Dawgz AI, which combines AI-driven automation with meme coin appeal, are gaining attention for their unique approach. In this article, we’ll explore top altcoins poised to benefit from these developments and why they might be worth considering for your portfolio.

What the HODL Summit Reveals About Altcoin Trends in 2025

Held in Dubai on May 14–15, the HODL Summit 2025 brings together some of the most influential voices in crypto and Web3. And this year’s focus is crystal clear: real-world adoption is no longer a dream, it’s already in motion.

The spotlight topics? Layer-2 scaling, real-world asset (RWA) tokenization, and AI integration. These aren’t just buzzwords anymore. From Ethereum rollups to tokenized treasury bills and automated AI-driven trading, projects that solve real problems are taking center stage.

Speakers at the event will highlight how these technologies are merging to build more scalable, secure, and intelligent blockchain systems.

For investors, the takeaway is simple: the best altcoins to buy now are the ones riding these trends early.

Best Altcoins to Buy Now: Layer-2, RWA, and AI Projects Leading the Way

With the HODL Summit setting the tone, investors are shifting focus toward altcoins that go beyond hype, coins that are building real infrastructure around Layer-2 speed, RWA utility and AI-driven functionality.

1. Dawgz AI ($DAGZ)

Dawgz AI is one of the more unique altcoins to watch in 2025 because it doesn’t just ride the meme coin wave, it builds on it with actual functionality. The project blends humor, accessibility, and community with AI-powered trading bots that run 24/7.

These bots are designed to help users earn passive rewards through automated strategies, even if they have zero trading experience. That makes it not only entertaining but also potentially useful, which is rare in the meme coin space.

Right now, Dawgz AI is still in presale and has already raised over $3.5 million USDT, with the current token price at $0.004. The next price hike is coming soon, which is why early adopters are taking notice.

It’s been audited by SolidProof, adding a layer of credibility that many early-stage tokens lack.

What makes it especially relevant this year is that Dawgz AI is positioning itself at the intersection of several key themes from the HODL Summit, AI automation, retail engagement, and simplified access to DeFi tools.

If you’re looking to diversify with something fresh but functional, this one could be worth keeping on your radar.

2. Arbitrum (ARB)

As one of the leading Layer-2 networks built on Ethereum, Arbitrum continues to dominate the conversation around blockchain scalability.

With gas fees still a major issue for everyday users and DeFi platforms, Arbitrum offers a real solution for faster and cheaper transactions while staying anchored to Ethereum’s security.

As of May 12, 2025, ARB is trading at $0.4705, showing a 1.57% daily gain, based on CoinMarketCap data. Its market cap is $2.23 billion, with a 24-hour trading volume of $399.4 million, showing strong market activity despite a temporary volume dip.

The current circulating supply stands at 4.75 billion ARB, out of a total supply of 10 billion tokens.

Zooming out, the recent price action paints a bullish picture. In just one week, ARB has climbed from roughly $0.32 to $0.47, marking a breakout fueled by renewed attention on Layer-2s.

As Ethereum continues to face congestion, Arbitrum’s adoption is only expected to grow, especially with more dApps, gaming platforms, and DeFi protocols migrating to its ecosystem.

3. Render (RENDER)

While most AI-related crypto projects focus on automation or user-facing tools, Render is all about powering the engines behind the scenes. It provides decentralized GPU rendering, a vital service for scaling AI models, gaming environments, and metaverse applications.

With demand for compute skyrocketing, RNDR is becoming essential for projects that need heavy lifting without relying on centralized cloud services.

As of May 12, 2025, Render is trading at $5.40, up 3
