Some of the biggest moves in crypto lately aren’t coming from Bitcoin alone but from altcoins building strong ecosystems or pulling in serious trading activity. These networks are showing up in whale wallets, stacking presale capital, or signing new deals with Web2 giants. If you’re looking for the top altcoins to buy now, the four listed below are getting real attention, not because of hype, but because of growth, speed, and usage. The recent rally in on-chain activity, presale momentum, and protocol upgrades across these altcoins makes them hard to ignore. BlockDAG’s presale is approaching a cut-off. Tron is still dominating stablecoin transfers. Aptos just signed deals with both Google Cloud and Franklin Templeton. And while Cosmos hasn’t made big headlines this month, its steady price climb is keeping it on radars. These are the top altcoins to buy now if you’re watching near-term moves with long-term potential. 1. BlockDAG – $235M Raised and Presale Ends May 13 BlockDAG is in its final presale stretch with over $235 million raised and 19.9 billion BDAG coins sold. The current price of $0.0019 is only available until May 13, after which it’s expected to rise. With a projected listing price of $0.05, the potential ROI sits around 2,520%. That upside is backed by major infrastructure already in place. Over 1 million users are active on the X1 mobile miner app, and 17,000 ASIC miners have already been shipped. A live beta testnet is also running, supporting 800 transactions per second. The network blends DAG architecture with Proof-of-Work to reach speeds up to 15,000 TPS while staying secure and efficient. It’s fully EVM-compatible and audited by CertiK and Halborn. A major referral campaign called Buyer Battles is distributing 100 million BDAG, with referrers earning a 25% bonus and referees getting 5%. More than $1.2 million in BDAG has been rewarded this week alone. BlockDAG has also secured a partnership with Inter Milan and is planning 10+ CEX listings. With real products, growing adoption, and short-term token availability ending soon, it’s not just another presale, it’s one of the top altcoins to buy now before the price moves up and supply tightens. 2. Tron – $19B Daily in Stablecoin Transfers Tron is holding strong at $0.2626 with steady volume support, having recently reached $0.2592 after some whale movement in late April. Its real strength, however, is in usage, especially for stablecoins. Tron moves $19 billion in USDT every day, making it the top chain for stablecoin transactions. Tether minted another $1 billion USDT on Tron recently, which further cements its role as a liquidity hub for exchanges and DeFi platforms. With over 303 million user accounts and 10 billion+ transactions, Tron’s usage stats are among the highest in crypto. Tron DAO is also making moves to expand TRX access across the U.S. through a new partnership with MoonPay, allowing users to buy TRX directly. That adds ease of access at a time when most retail users are looking for fast onboarding. While it may not be making loud headlines, Tron’s quiet consistency in high-volume use cases keeps it on every serious watchlist of top altcoins to buy now. 3. Aptos – Token Unlock Ahead, But Trading Volume Spikes Aptos is back in the spotlight with a price of $6.01 and a 5.81% gain over the past 24 hours. On May 12, the network will unlock 11.31 million APT tokens, roughly $65 million worth, yet the sentiment around this unlock is different. There’s a sharp rise in buying activity on Binance, where APT’s order book is showing 60% more buys than sells. Daily active addresses have jumped 25% to hit 120,000, showing increasing user traction ahead of the unlock event. Analysts are watching how the market responds, but on-chain data shows growing interest. Backing the optimism is a wave of new partnerships. Google Cloud is working with Aptos on blockchain-based AI integration, while Franklin Templeton plans to launch a tokenized fund using Aptos infrastructure. The network itself has improved block speeds by 40% in just 2.5 months, dropping from 220ms to 130ms. Aptos also has a strong technical setup with its RSI still under 60 and a bullish MACD crossover in play. These shifts support why it’s one of the top altcoins to buy now, especially ahead of more network expansion. 4. Cosmos – Stable Climb Despite a Quiet Month Cosmos (ATOM) has seen a quiet but consistent performance this month, trading at $5.28 with a 5.18% 24-hour gain. While there have been no major headlines or upgrades since April 25, its price range and resilience are keeping it in play. The recent highs and lows of $5.40 and $5.00 show that ATOM is bouncing within a strong support zone. Traders are watching for breakouts, but the base is solid and daily sentiment remains bullish without any aggressive sell pressure. Even without big announcements, Cosmos still holds relevance because of its core interoperability mission. It powers multiple zones and remains foundational to networks using IBC (Inter-Blockchain Communication). Many developers continue to build on Cosmos SDK, which gives it long-term value even during short quiet periods. While it’s not surging in headlines right now, its steady price action and deep utility layer are good enough reasons to count it among the top altcoins to buy now, especially for those eyeing undervalued infrastructure tokens. Key Insights When looking at the top altcoins to buy now, what really matters is whether they’re active, on-chain, in the news, or inside user wallets. BlockDAG has momentum from every angle: presale funds, tech milestones, mining hardware, and user participation. Tron continues leading stablecoin flows with strong partnerships and network stats. Aptos is speeding up and bringing in big names from TradFi and Web2. Cosmos is holding its ground and staying relevant as a cross-chain backbone. Each of these networks brings a different type of value, BlockDAG is about early-stage access with upside, Tron is about scale and liquidity, Aptos is about speed and innovation, and Cosmos is about steady infrastructure. If you’re tracking where attention, users, and development are going, these four rank among the strongest top altcoins to buy now heading into the second half of 2025.
