The Top 10 Altcoins of H1 2025
Before we dive into comparative analysis, let’s take a look at the best altcoins for 2025:
Saros (SAROS):1,379%
Saros surged 1,379% in H1 2025, setting a record among top 300 crypto assets, driven by the launch of its Dynamic Liquidity Market Maker (DLMM). This made it one of the best coins to invest in 2025.
Product innovations like its DLMM, AMM, decentralized perpetuals exchange, staking, and launchpad fueled adoption on Solana, attracting liquidity providers and traders.
Strong user engagement and growing DeFi activity could sustain momentum, while ongoing market volatility and regulatory uncertainties remain potential risks for the token.
Onyxcoin (XCN): 551%
XCN is one of the top altcoins in 2025, and its price surged 550% in the first half of the year, driven by the Binance Futures listing and increased trading activity following its mainnet launch.
Shift to a Layer 3 blockchain using Arbitrum Orbit and Coinbase Base, a new whitepaper narrative, staking, and democratized governance through the Onyx DAO drove adoption and community engagement.
Technical innovation and strong community participation can help maintain growth, although regulatory developments and market volatility remain key risks to XCN’s momentum.
Zebec Network (ZBCN): 298%
ZBCN’s price surged by 298% in H1 2025, after a key partnership with Circle to integrate USDC across its products.
Growth was fueled by the launch of its RWA payment network, real-time payroll streaming, crypto-enabled Mastercard cards, treasury solutions, and strategic acquisitions like WageLink and Gatenox, enhanced with Web3 capabilities.
Zebec’s focus on bridging real-world payments with blockchain and expanding adoption could sustain momentum, though market volatility and regulatory risks remain key considerations for ZBCN.
Maple Finance (SYRUP): 288%
Another top altcoin in 2025 is SYRUP. It rose 288% in H1 2025, climbing from $0.156 to a high of $0.65 per token, with total value locked (TVL) growing from $510M to $3B.
Growth was fueled by a pivot to over-collateralized lending, the launch of the Syrup protocol and SyrupUSDC, partnerships with CoreDAO, Lido, and integration with platforms like Ether.fi and Pendle, plus expansion to Solana.
Institutional adoption, including listing by Grayscale, also boosted demand. Continued product expansion, DeFi integrations, and yield-bearing offerings could sustain growth, though regulatory and market risks remain.
Toshi (TOSHI): 284%
TOSHI grew 284% in H1 2025, climbing from its January 1 price to $0.0048 by June 30, ranking as the fifth-best-performing asset among the top 300 cryptos.
Key growth factors included exchange listings on Coinbase, Bybit, and Kraken, as well as strong community engagement and platform developments such as Toshi Mart, a memecoin launchpad on Base Layer 2.
Continued community support, platform utility expansion, and wider adoption could sustain momentum, though market volatility and meme-coin-specific risks remain key considerations for TOSHI’s performance.
Venom (VENOM): 255%
VENOM grew 255% in H1 2025, rising from $0.05 on January 1 to $0.184 by June 30, making it the sixth-highest gainer among top 300 crypto assets.
Growth was fueled by its Layer 0/1 scalable blockchain, successful stress tests demonstrating 150,000 TPS, and outreach to Southeast Asian central banks and regulators for co-development of financial systems.
Venom’s enterprise-grade capabilities and focus on high-performance infrastructure could sustain adoption, though regulatory engagement and market volatility remain important considerations for its future growth.
Euler (EUL): 120%
EUL surged 120% alongside a 900% TVL growth in H1 2025, with locked assets rising from $110M to over $1.1B across lending pools and EulerSwap, making it one of the top performing cryptocurrencies.
Growth was driven by Euler V2’s modular DeFi architecture, which includes the Euler Vault Kit (EVK) for isolated lending vaults and the Ethereum Vault Connector (EVC), enabling cross-vault collateral usage and attracting both retail and institutional users.
Euler’s innovative lending framework positions it for continued adoption in DeFi, though market volatility and competitive pressures remain potential risks to token performance.
WhiteBIT Coin (WBT): 90%
WBT rose 90% in H1 2025, reaching a record high of $52.27 on June 16, making it the eighth-best-performing asset among the top 300.
Price growth was fueled by marketing and brand initiatives, including a multi-year sponsorship deal with Juventus, alongside the adoption of WhiteBIT Exchange and its WhiteChain Layer 1 network for fast, low-cost transactions.
Strong platform adoption, growing ecosystem utility, and continued brand visibility could sustain momentum, though market volatility and competition in the crypto exchange space remain key risks for WBT.
Hyperliquid (HYPE): 65%
HYPE rose 65% in H1 2025, climbing from just over $24 on January 1 to $39.7 by June 30, peaking at $45.57 on June 16, ranking ninth among top 300 crypto assets.
Growth was fueled by surging platform activity with TVL rising from $400M to $2.2B, the launch of HyperEVM for EVM-based dApps, and the token’s use in governance and staking incentives.
Continued platform adoption, smart contract development, and derivatives trading growth could sustain momentum, though market volatility and competitive pressures remain potential risks for HYPE.
Monero (XMR): 62%
XMR rose 62% in H1 2025, making it the tenth-best-performing asset among the top 300 crypto tokens.
Growth was driven by its privacy-focused design, ongoing developments like the ‘Fluorine Fermi’ upgrades, and increased attention to privacy coins amid the Tornado Cash case, strengthening its narrative as a censorship-resistant digital currency.
Continued protocol upgrades, strong community development, and the growing demand for privacy-preserving crypto could support XMR’s momentum, though regulatory scrutiny remains a key consideration.

Comparative Analysis
The top-performing altcoins in 2025 share some common threads, yet they also differ in how they achieved success.
Common Threads:
- Meme Coins: Tokens like TOSHI thrived on strong community engagement, social media virality, and platform-driven utility, such as launchpads, demonstrating how culture and hype can drive price action.
- RWA and DeFi Tokens: Assets such as Zebec (ZBCN), Maple (SYRUP), SAROS, and Euler (EUL) benefited from institutional interest, growing adoption, and tangible utility in bridging real-world assets or providing decentralized financial services.
- AI/Blockchain Convergence: Some projects, including SAROS, gained attention by integrating AI tools or promising more innovative decentralized finance solutions, reflecting broader hype around AI + blockchain in 2025.
Differences:
While meme coins rely heavily on community momentum, RWA and DeFi tokens are supported by real-world adoption, strategic partnerships, and innovative protocol development.
AI/blockchain projects emphasize technical innovation and forward-looking utility, rather than short-term virality. Similarly, privacy coins like Monero attract users for their security and censorship resistance, rather than hype or institutional interest.
Risks & Considerations
While the top altcoins in 2025 delivered impressive gains, several risks remain for investors. Volatility is high across the crypto market, meaning prices can swing dramatically in a short time, so they may not be the top altcoins to buy now.
Many coins, especially meme tokens, are driven by speculative hype, which can fade quickly. Additionally, evolving regulatory frameworks in different countries create uncertainty that could impact adoption and token value.
Retail investors should exercise caution when chasing past performance, as historical gains do not guarantee future returns. It’s important to do your own research, assess risk tolerance, and consider long-term potential before investing.
