Best Altcoins to Buy Now: BlockDAG, Ethereum, Chainlink, Cardano Set the Stage for Explosive Growth

4 Best Altcoins to Buy Now: BlockDAG, Ethereum, Chainlink, & Cardano Could Lead the Next Bull Market Surge

As the crypto market gears up for its next major run, a select few projects are emerging as potential leaders for 2025. These aren’t fleeting hype plays but platforms with strong fundamentals, network upgrades, and practical applications. Established names like Ethereum and Cardano continue to strengthen, while new arrivals like BlockDAG are drawing attention with impressive funding milestones and large-scale adoption plans.

In this overview of the best altcoins to buy now, we examine four projects making a strong case for long-term growth. Ethereum’s institutional traction, Chainlink’s expansion into CBDC connectivity, and Cardano’s renewed developer funding are all key drivers. Still, it’s BlockDAG, now priced at $0.0276 after raising $370 million and selling over 25 billion coins across 29 batches, that’s turning heads with a projected 2,660% return for its earliest participants.

1. BlockDAG: Low Entry Price with Major ROI Potential

BlockDAG is one of the most closely watched names among the best altcoins to buy now, offering a Layer 1 framework that merges DAG scalability with Proof-of-Work security. Currently priced at $0.0276 in Batch 29, it has already secured $370 million in funding. Early participants from the first batch are eyeing a projected 2,660% ROI.

Beyond its fundraising success, BlockDAG’s traction is evident. It has drawn in 2.5 million mobile app users via the X1 mining app and sold 19,000 ASIC miners, showing both community engagement and hardware adoption.

In a space where many projects remain theoretical, BlockDAG stands out with operational products, active users, and a detailed roadmap. For those tracking the best altcoins to buy now, it offers a compelling balance of low entry pricing, proven traction, and high upside potential.

2. Chainlink: Expanding From Oracle to Core Infrastructure

Chainlink’s role as a trusted data oracle has been pivotal to blockchain operations, but its reach is expanding. In a recent milestone, Chainlink and Visa completed a pilot for cross-border CBDC–stablecoin transactions between Hong Kong and Australia. This reduced intermediaries and improved settlement times, demonstrating LINK’s ability to deliver on large-scale, real-world use cases.

Its relevance among the best altcoins to buy now comes from this broad utility, powering DeFi platforms, enabling CBDC interoperability, and supporting tokenised asset infrastructure. The CBDC pilot reinforces Chainlink’s readiness for institutional-grade systems, positioning it as a key player in the future of cross-border value exchange.

With central banks and corporations exploring tokenised payment rails, LINK’s integration into these systems could establish it as a foundational protocol in global finance.

3. Ethereum: Institutional Accumulation, Layer 2 Growth, and Price Targets

Ethereum continues to hold a prime position in the conversation about the best altcoins to buy now. Institutions are building substantial ETH positions, using it both as a long-term store of value and a yield-generating asset. Public companies collectively hold more than 966,000 ETH (around $3.5 billion) as of July 2025, a sharp rise from 116,000 ETH in late 2024.

Trading near $3,700, Ethereum could see a rally toward $8,000 if it breaks past $4,000. This outlook is supported by post-Dencun upgrades, expanding Layer 2 solutions like Arbitrum and Base, and wider adoption in decentralised finance. Staking returns of 3–4% remain attractive, though regulation continues to be a factor to monitor.

Ethereum’s unmatched developer ecosystem, liquidity depth, and proven scalability make it a core holding for long-term portfolios.

4. Cardano: Developer Treasury Boost Signals Renewed Growth

Cardano’s path this year has been uneven, but fresh funding is injecting momentum. The community approved a $71 million (96.8 million ADA) allocation to support Input Output Engineering’s 2025 development roadmap. This commitment strengthens the network’s capacity to deliver upgrades and expand functionality.

Price action remains choppy, with whale sell-offs of over 180 million ADA in recent days keeping ADA around $0.63. A move beyond $0.75 would mark a stronger reversal, but the fundamentals remain intact. Cardano’s slow-and-steady development style, combined with robust governance, gives it durability in a market prone to overextension.

For those evaluating the best altcoins to buy now, Cardano’s mix of funding support and ecosystem maturity makes it a strong candidate for long-term growth.

The Bottom Line on 2025’s Strongest Contenders

Crypto’s next growth cycle is likely to reward delivery over empty hype. BlockDAG, Ethereum, Chainlink, and Cardano are all progressing with tangible developments and solid market positioning.

BlockDAG offers rare upside with proven user adoption and early-backer rewards. Ethereum remains the most established smart contract platform with deep institutional trust. Chainlink is embedding itself into the future of CBDCs and tokenised settlements. Cardano is reinforcing its long-term vision through significant developer funding.

As capital returns to high-confidence projects, these are among the best altcoins to buy now, projects not only prepared to ride the next wave but also to help shape it.
