Best Altcoins to Buy Now: BlockDAG, LINK, HBAR & ONDO Show Real Growth Signs

As the second half of 2025 begins, many are once again looking for the next strong performers in crypto. This year’s market surge has brought attention to projects with scalable systems, real-world asset connections, and key Web3 services. But finding the best altcoins to buy now means spotting growth early, before listings, ETFs, or mainstream demand drive prices higher.

Four projects are now leading the conversation: BlockDAG, Chainlink (LINK), Hedera (HBAR), and ONDO Finance. Each plays a different role in the Web3 world, from core infrastructure to advanced finance tools, but they share one thing, active development, expanding users, and long-term potential.

Here’s a look at why these four may be the best altcoins to buy now, and why BlockDAG’s $0.0016 price could soon be history.

BlockDAG (BDAG) 

BlockDAG is gaining traction as one of the best altcoins to buy now, and its recent numbers highlight why. It has raised over $355 million in its ongoing presale and sold more than 24.4 billion BDAG. Its hybrid design blends Proof-of-Work with DAG, making it scalable, energy-aware, and decentralized.

Two key tools lead its growth. First, the X1 mobile app, already used by over 2.5 million people worldwide. Second, the X10 miner, a simple device with 18,800 units sold, bringing mining to more homes and more users. These tools help make BDAG more accessible and widely used.

What makes BlockDAG (BDAG) notable at this moment is its No Vesting Pass. Those who take part before the August 11 GLOBAL LAUNCH release will have full access to BDAG on day one. With a current price of $0.0016 and a confirmed listing at $0.05, this setup offers a possible 3,025% return. With over 4,500 developers creating 300+ dApps already, BlockDAG’s pace is driven by progress, not just attention.

Chainlink (LINK)

Chainlink continues to hold a strong position among the best altcoins to buy now due to its steady technical progress and key role in the Web3 space. LINK is trading near $18.92, showing a 2.8% gain in the last 24 hours and a weekly rise of over 3.3%, putting it among the more stable large-cap coins in the current cycle.

On-chain trends show ongoing exchange outflows, pointing to long-term holding and growing interest from larger players. The use case remains clear, Chainlink’s decentralized oracles are critical to hundreds of smart contract-based apps.

From a chart view, LINK is forming a rising channel and testing resistance around $19. With current momentum, a move past $20 is possible. As more platforms rely on Chainlink for secure data feeds, it continues to be a major name in DeFi and cross-chain services. Its long-term presence and role in building trust across networks make it one of the best altcoins to buy now.

Hedera (HBAR)

Hedera has seen a strong performance this month, rising more than 100% and crossing the $0.30 mark for the first time in 2025. A recent 9% daily gain has boosted attention, helped by its listing on Robinhood, which expanded its reach in the U.S.

Analysts highlight a Crab harmonic pattern that signals a possible price move to $0.426, which would mean a 45% upside. Technically, HBAR remains above important moving averages and holds support in previous accumulation zones between $0.13 and $0.17.

Its focus on fast performance and energy-aware consensus continues to attract attention from those who prefer steady growth. If volume stays high and price stays above key breakout levels, HBAR may continue its run as one of the best altcoins to buy now for those focused on useful network tech.

ONDO Finance (ONDO)

ONDO is gaining ground this year as one of the top platforms for tokenizing real-world assets. It trades at around $1.05, with daily volume between $140 and $145 million, showing steady activity despite wider market changes.

The recent ETF filing by 21Shares for a spot ONDO product shows growing institutional interest, which may lead to more market access. ONDO’s launch of tokenized U.S. Treasuries on the Sei blockchain also supports its position in long-term financial tools.

Technically, ONDO is moving between support at $0.95–$1.05 and resistance at $1.16. A breakout above that could lead to $1.25–$1.35 soon. With its strong setup and clear link to real-world finance, ONDO is one of the best altcoins to buy now as the DeFi sector continues to evolve.

Four Projects Making Their Mark in 2025

In a space full of hype, BlockDAG, Chainlink, Hedera, and ONDO stand out due to real progress, strong developer activity, and important price patterns. Whether it’s Chainlink’s data tools, Hedera’s enterprise reach, ONDO’s RWA model, or BlockDAG’s active user system, each brings value in a different way.

BlockDAG is especially notable with signs that it could be a major new Layer 1 project. At a presale price of $0.0016 and a listing goal of $0.05, the potential return setup is uncommon. Alongside working apps, daily users, and more than 4,500 builders, it is already among the best altcoins to buy now, even before going live.

For anyone tracking smart moves in 2025, these four names stand out. Once wider attention arrives, the best entry chances may already be behind.
