5 Altcoins to Watch in May 2025 After the Explosive Rise in April

April 2025 witnessed major altcoins like SUI, HYPE, and SOL reaching double-digit growth. With institutional moves and increasing on-chain activity driving momentum, this is what to expect from the best-performing altcoins in May 2025. The cryptocurrency market closed in April 2025 on a high note, with some altcoins in the top 20 delivering excellent monthly returns. From ETF records to ecosystem growth, projects like Sui and HYPE have caught the attention of investors. As May begins, all eyes are on whether these tokens can maintain their growth momentum or face a correction. Let's take a closer look at the 5 highest-performing altcoins from April 2025 and what next month might bring for each of them.

🥇 Sui (SUI): Riding the ETF Wave Performance in April: +61.56% Market capitalization ranking: #11 SUI led the altcoin group in April after 21Shares filed for the first spot SUI ETF with the US SEC. This bold move not only legitimized the Layer 1 blockchain in the eyes of institutions but also sparked speculative interest among traders. The growing ecosystem of SUI and its active developer base have further boosted its appeal.

Prospects for May 2025: SUI may continue to rise higher, especially if the optimism surrounding the ETF persists. However, after such a strong monthly rally, the token may undergo a short-term consolidation before rising again. 🥈 Hyperliquid (HYPE): The New Favorite Coin of DeFi Traders Performance in April: +55.43% Market capitalization rank: #20 Hyperliquid, a rising star in the decentralized futures market, gained significant traction in April. Its innovative model as a decentralized derivatives exchange has attracted users seeking alternatives to centralized platforms. The increase in DeFi trading volume also played a role in the price surge of HYPE.

Prospects for May 2025: HYPE remains the center of attention and if the trading volume on-chain stays high, the token could rise further. However, considering its high volatility, expect strong pullbacks and profit-taking phases. 🥉 Solana (SOL): Back to the Game Performance in April: +20.96% Market capitalization ranking: #6 Solana made a strong recovery in April amid renewed interest in meme coins and NFT activity on its high-speed chain. Discussions about a potential ETF based on Solana have also sparked optimism. The ecosystem has continued to grow despite previous obstacles.

Prospects for May 2025: SOL may trade sideways or see a slight increase at the beginning of the month, but any specific news regarding ETF approval or major launches could trigger a breakout. 🏅 Bitcoin Cash (BCH): Asset Recovery April performance: +19.67% Market capitalization ranking: #19 Bitcoin Cash quietly rose in price in April, attracting the attention of investors seeking faster and cheaper transactions. It benefited from a rotation into older, undervalued coins and the growing narrative surrounding digital currency utility.

Prospects for May 2025: If there is no strong development of the ecosystem, the growth momentum of BCH may weaken. However, it may still benefit from retail-driven transactions and speculative capital circulation. 🏅 Hedera (HBAR): The Pioneer in Business Tokenization Performance for April: +15.53% Market capitalization rank: #17 HBAR has steadily increased in April thanks to strategic partnerships with global companies such as IBM, Dell, and initiatives related to carbon credit coding. The focus on real-world use cases continues to strengthen its fundamentals.

Prospects for May 2025: If Hedera ensures more enterprise integrations or expands token use cases, HBAR could witness sustainable growth in the long term until May and beyond. Outlook for May 2025: Momentum or Correction? April is a strong month for altcoin, but the current question is whether these price increases can hold. With the development of ETFs, ecosystem upgrades, and the use of DeFi driving narratives, top altcoins are poised for the potential to continue — but volatility remains high. Investors should monitor macroeconomic changes and news catalysts to get ahead into May 2025.
