Hoping to stay ahead in the 2025 cycle? In crypto, timing can change everything. As major names move closer to daily use and wider access, the space is seeing serious traction. New technologies, rising user numbers, and strong project updates are pushing some coins higher. Not all will hold up, though; a few are clearly moving toward stronger roles while others slow down.
This list looks at the next biggest altcoins based on their current moves, ecosystem strength, and upcoming developments. From large-scale mining rollouts to real-world tech use, these four coins are showing strong signs. First up is BlockDAG, the only presale coin in this group, followed by solid picks like Cardano, Tron, and Stellar.
1. BlockDAG: Rapid Growth, Strong Mining Setup, and Presale Surge
BlockDAG is quickly becoming a major name as it nears the end of its presale phase. Currently in Batch 29, the BDAG coin is priced at $0.0020 until June 24, after which it rises to $0.0030. The projected listing price stands at $0.05, meaning early supporters could see 25x gains if the launch target is met. With 23.2 billion coins sold and $320.5 million already raised, this isn’t a small-scale event; it’s one of the largest presales of 2025 so far.
The tech setup includes over 2 million users already active on its X1 mobile mining app, and an upcoming delivery of X30 and X100 miners in July, with the X10 expected by mid-August. Security has been a focus, too. BlockDAG (BDAG) has completed one audit with Halborn and is undergoing another with CertiK.
Following the recently completed “GO LIVE” reveal, the project has confirmed listings on 20 exchanges, including MEXC, LBANK, BitMart, XT.com, and CoinStore. With tools to support liquidity and reduce launch volatility, BlockDAG has already given early backers a 2,660% rise in value since Batch 1. It earns its place among the next biggest altcoins for its real user activity, fast rollout, and limited-time pricing window.
2. Cardano: Enterprise Focus and Growing DeFi Moves
Cardano (ADA), trading near $0.565 in late June 2025, has seen a minor dip, about 2% today and 9% over the past week. But beyond the price charts, there’s more in motion. Whale wallets moved 230 million ADA recently, sparking discussion. Meanwhile, the Cardano treasury is boosting efforts in DeFi and stablecoin tools.
The network is staking over 22 billion ADA across roughly 3,000 pools and now records over 110 million on-chain transactions. A notable event this month is a pilot with Ford Motor Company. It’s built using Cardano’s Iagon protocol for secure document storage. These kinds of trials point to real-world use that can matter in the long run. ADA isn’t surging right now, but solid fundamentals and enterprise steps make it one of the next biggest altcoins to monitor.
3. Tron: An Expanding Stablecoin Base
Tron (TRX) has stayed around $0.274 and continues to expand. It’s entering the public market through a reverse merger with Nasdaq-listed SRM Entertainment, forming “Tron Inc.” This deal is valued at up to $210 million, and SRM’s stock jumped more than 650% on the news. Few crypto projects have made this move, showing long-term planning.
Smart contract energy use on Tron has jumped 108% year-over-year. The JUST DeFi protocol running on Tron holds $9.2 billion in TVL, and the network manages about $78 billion in stablecoins, mostly in USDT. A recent Nobitex breach impacted some TRX-linked holdings, but Tron’s core systems were not responsible. With scale, high daily use, and public trading steps in place, TRX makes a case for being one of the next biggest altcoins this year.
4. Stellar: Consistent in Digital Payments Utility
Stellar (XLM) is trading close to $0.238 after a small 2% drop. Though the price has held steady, Stellar keeps showing up in use cases around digital transfers and cost-efficient payments. As of mid-June, no big new deals have been shared, but Stellar is still active in areas like token distribution and financial tools.
What keeps it relevant is the stable tech it offers and its ability to serve fintech builders. Speed, simplicity, and trust make it attractive to those creating tools in finance. It might not be the most hyped, but XLM’s real value shows up when demand for digital payment rails increases. With that in mind, Stellar stays on the list of the next biggest altcoins to watch as things heat up.
Final Take!
With market energy building up again, choosing which altcoins to follow can make a big difference. BlockDAG brings huge presale numbers, solid miner delivery, and US-based sponsorships. Cardano keeps working with major firms and building tools for stable DeFi growth. Tron is now heading into public trading, and Stellar continues to deliver on payment tech.
While each one stands apart in focus, these four next biggest altcoins are all worth tracking now. Their progress, updates, and consistent results give them an edge heading into 2025. If you’re planning for the future, keeping an eye on these could pay off before the next price rally begins.
