4 Best Altcoins to Watch in 2025: BlockDAG, Solana, TRON & Ethereum Are on Every Whale’s Radar
Are you seeing prices shift day by day and wondering which cryptocurrencies big holders are buying? With market uncertainty as retail sits on the sidelines, whales are quietly accumulating smartly. They’re focusing on BlockDAG, Solana, TRON, and Ethereum.
These aren’t casual picks; they each show real growth in tech, adoption, or support. Among them, BlockDAG stands out. This emerging Layer 1, with a mix of Proof‑of‑Work security and DAG scalability, is drawing attention as one of the best altcoins to watch. Let’s dig into why these four are currently on the radars of whales.
1. BlockDAG: Whales Betting on Hybrid Tech
Whales are buying into a project combining PoW and DAG for faster speeds and strong decentralization. It’s more than hype: BlockDAG (BDAG) has raised $325 million across 29 Batches and sold over 23.3 billion coins. Those who bought BDAG in Batch 1 are looking at a 2,660% return in Batch 29.
It supports thousands of transactions per second while remaining compatible with Ethereum’s smart contracts. Over 18,000 ASIC miners have been sold, and 2 million users have downloaded the X1 Miner App, making it accessible to many. These numbers reflect strong groundwork, not just buzz.
The team also rolled out a 100 million coin airdrop for users, based on testnet activity, referrals, miner purchases, and social sharing. It’s a community-first approach, building interest ahead of the mainnet. The presale is currently offering a special limited-time price of $0.0080.
Whales are taking note of this trajectory. As it heads toward its mainnet debut in late 2025, BlockDAG is being marked as one of the best altcoins to watch, with infrastructure, community, and price momentum all coming together.
2. Solana: Real-World Deals Fuel Growth
Solana (SOL) continues to attract large holders. With its high-speed and low-cost network, it’s a top choice for DeFi and NFT platforms. SOL is trading around $144 and has recently climbed due to a deal with Kazakhstan’s Digital Development Ministry.
This partnership aims to bring local capital markets onto Solana’s blockchain, expanding real-world use. The network also hosts growing DePIN and AI projects. All of this makes SOL worthy of the best altcoins to watch list by whales.
3. TRON: Eyeing Public Markets and Visibility
TRON (TRX) is quietly making a comeback. With a system that can process 2,000 transactions per second, it’s ideal for high-demand apps. This month, whales took note when TRON announced plans to become public in the U.S. through a reverse merger with a Nasdaq-listed firm.
That step could make it the first major Layer 1 tied directly to equity markets. TRX saw a 2% jump in response, and whales are viewing this as a sign of institutional growth. TRON now ranks among the best altcoins to watch for its link between Web2 and Web3 possibilities.
4. Ethereum: Strong Foundation with Upgrade Momentum
Ethereum (ETH) remains essential among whale portfolios. Though prices move often, ETH is still the second-largest coin by market cap. More than 55% of DeFi value locks reside on Ethereum.
After the recent Pectra upgrade, improving speed, cutting gas fees, and adding identity support, ETH trades near $2,424, with analysts eyeing $2,850. Its blend of stability and innovation makes it one of the best altcoins to watch, even as newer platforms gain attention.
Final Take
While the overall market remains uncertain, whales are quietly building their positions. What connects BlockDAG, Solana, TRON, and Ethereum is their strong infrastructure, growing user base, and long-term potential. BlockDAG stands out as the only one still in presale, with a very low entry price and a full ecosystem already in place. It has raised $325 million, sold 23.3 billion coins, and seen over 2 million downloads of its X1 Miner App.
These numbers show strong traction even before launch. With a 100 million BDAG airdrop and a U.S.-based sponsorship added in, whales are clearly paying attention. For everyday buyers, these moves suggest which cryptos could lead the next big wave, and BlockDAG is one of the best altcoins to watch.
