The cryptocurrency market witnessed a powerful altcoin rebound on April 30, 2025, signaling renewed momentum and potential opportunities for traders. According to a widely shared update from Crypto Rover at 14:23 UTC, major altcoins surged double digits within 24 hours, reigniting investor interest and boosting network activity across leading blockchain platforms.
At 15:00 UTC, CoinMarketCap data showed Ethereum (ETH) climbing 12.3% to $3,250.47, Solana (SOL) rising 14.7% to $182.35, and Cardano (ADA) gaining 10.9% to $0.48. This broad-based rally was supported by a significant spike in trading volume—Ethereum reached $18.2 billion in 24-hour volume, Solana hit $4.5 billion, and Cardano recorded $1.1 billion, according to CoinGecko’s report at 16:00 UTC.
On-Chain Activity Confirms Growing Momentum
Beyond price action, on-chain metrics further validated the strength of this rally. Glassnode data from 17:00 UTC revealed that Ethereum’s daily active addresses jumped 8.5% to 1.2 million, while Solana processed 5.4 million transactions—a 22% increase—highlighting robust user engagement and network utilization.
Notably, large-scale movements also pointed to institutional or whale interest. Santiment reported at 19:00 UTC that Ethereum saw a 15% rise in whale transactions—those exceeding $100,000—totaling 3,500 over the past day. Such activity often precedes sustained price movements, as large holders typically accumulate before major upside runs.

Technical Indicators Signal Bullish Outlook
From a technical perspective, key indicators suggest continued bullish potential—though some assets are approaching overbought territory.
As of 21:00 UTC, TradingView data showed Ethereum’s daily RSI at 68, nearing the 70 threshold that traditionally signals overbought conditions. Solana’s RSI stood higher at 72, indicating stronger short-term momentum but also increased vulnerability to pullbacks. Cardano’s RSI at 65 remains within healthy range, suggesting room for further upside.
The MACD indicator confirmed bullish momentum across the board. Ethereum’s MACD line reached 25.3 with a clear bullish crossover, Solana’s stood at 18.7, and even Cardano showed positive momentum with a MACD value of 0.012 at 22:00 UTC. These readings reflect accelerating upward momentum and growing buying pressure.
Volume-based analysis adds further credibility. On-Balance Volume (OBV) rose across all three networks: Ethereum’s OBV increased 7.2% to 5.1 billion, Solana’s grew 9.8% to 1.3 billion, and Cardano’s climbed 5.5% to 820 million by 23:00 UTC (CoinGecko). Rising OBV alongside higher prices confirms that the rally is backed by genuine demand rather than speculative noise.
Strategic Entry and Exit Zones for Traders
For active traders, identifying key support and resistance levels is crucial for timing entries and managing risk.
According to TradingView data at 18:00 UTC:
- Ethereum faces resistance at $3,300, with immediate support at $3,150.
- Solana meets resistance at $190, with support holding near $175.
- Cardano eyes a psychological barrier at $0.50, with strong support at $0.45.

Additionally, trading pairs like ETH/USDT saw a 35% surge in 24-hour volume to $9.8 billion on Binance, while SOL/USDT volume rose 28% to $3.2 billion—indicating strong liquidity and market participation.
AI Tokens Gain Traction Amid Broader Rally
The resurgence of AI-themed cryptocurrencies further underscored thematic strength in the market. Fetch.ai (FET), a prominent player in the AI-blockchain space, climbed 9.8% to $1.35 by 20:00 UTC, with its 24-hour trading volume reaching $320 million (CoinMarketCap).
This performance highlights the growing synergy between artificial intelligence and decentralized technologies—a trend increasingly attracting retail and institutional capital alike.
