5 Altcoins to Watch as Market RSI Slumps to 28 - Potential Gains Up to 30%

The cryptocurrency market in late 2025 is navigating a correctionary phase, with Bitcoin's RSI hovering near 32.58-a level historically associated with oversold conditions according to Nasdaq. This environment, while volatile, has created fertile ground for undervalued altcoins to emerge as potential outperformers. As institutional and retail capital rotate into projects with resilient fundamentals and strong technical setups, five altcoins stand out for their ability to withstand the downturn and position themselves for a rebound. Below, we analyze these assets through the lens of RSI, support levels, and on-chain metrics, identifying opportunities for investors seeking exposure to altseason 3.0.

1. Chainlink (LINK): The Oracle of DeFi's Resilience

Chainlink (LINK) has carved a niche as the backbone of decentralized finance, providing critical oracle infrastructure for smart contracts. Despite Bitcoin's 6.4% 24-hour drop according to Nasdaq, LINK has held above $12, consolidating near a key support level. Technical indicators, however, remain bearish: the 14-day RSI at 41.013 according to Investing.com and 11 sell signals across moving averages according to Investing.com suggest continued downward pressure. Yet, LINK's institutional adoption-such as JPMorgan's use of its Cross-Chain Interoperability Protocol-positions it as a long-term play. If buyers step in to defend the $11.40 support level according to TMGM, a 30% rebound to $15 could materialize, aligning with its expanding utility in cross-chain ecosystems.

2. Polygon (MATIC): Oversold but Poised for Reversal

Polygon (MATIC) has demonstrated technical resilience amid the broader selloff. Its RSI of 25.4 according to AltIndex signals oversold territory, while the MACD line remains above the signal line, hinting at bullish momentum according to AltIndex. MATIC's 50-day and 200-day moving averages converging at the same price point according to AltIndex suggest a potential consolidation phase. Fundamentally, Polygon's partnerships with global brands like Nike and Disney according to Yellow, coupled with its transition to zero-knowledge rollups, underscore its scalability narrative. A break above $0.85 could trigger a 30% move to $1.10, leveraging its role as Ethereum's scaling solution.

3. XRP: Legal Uncertainty Meets Technical Setup

Ripple's XRP has faced a 20% decline in November 2025, trading at $2.34 according to Yahoo Finance. However, technical analysis suggests a potential rebound. Elliott Wave theory indicates XRP must retest the $2.05 level before a bounce to $2.36 according to Yahoo Finance, with RSI confirming oversold conditions at this threshold. Institutional validation, such as the Grayscale Sui Trust's $4.23 million AUM according to Blockchain Reporter, adds credibility to its long-term prospects. If XRP regains $2.70-a level last seen in January 2025-investors could see a 30% gain.

4. Cardano (ADA): Deep Undervaluation and On-Chain Optimism

Cardano (ADA) has fallen to $0.46, breaching key support levels according to Yahoo Finance. On-chain data reveals a 30-day MVRV ratio of -19.7%, signaling an "Extreme Buy Zone" according to Yahoo Finance. While ADA's RSI at 33.88 according to Cryptonomist is not yet in extreme oversold territory, a stabilization near $0.39 and a bullish divergence in MACD according to CryptoSlate hint at a potential reversal. Fundamentally, ADA's 3.17 million holders according to Yahoo Finance and $30 million liquidity initiative according to CryptoSlate aim to bolster DeFi adoption. A rebound to $0.53 could deliver a 30% return, assuming buyers reclaim the $0.49–$0.51 resistance zone according to TMGM.

5. Sui (SUI): Institutional Backing and Technical Strength

Sui (SUI) has outperformed peers during the correction, maintaining support levels from early 2023 according to Blockchain Reporter. Its 46% drop from $5.35 according to Blockchain Reporter has created a compelling entry point, with RSI signaling oversold conditions. Institutional validation, including the Grayscale Sui Trust's OTCQX listing according to Blockchain Reporter, underscores its credibility. Technologically, Sui's high transaction throughput and innovations like zkLogin position it for long-term growth. A 30% move to $1.50 from its current $1.10 level would align with its on-chain fundamentals and institutional adoption.

Conclusion: Positioning for Altseason 3.0

The current market phase, marked by Bitcoin's RSI near 32.58 according to Nasdaq, reflects a correctionary environment where undervalued altcoins with strong fundamentals and technical setups can thrive. The five projects above-Chainlink, Polygon, XRP, Cardano, and Sui-each present unique catalysts for a 30% rebound. While volatility remains a risk, the combination of oversold RSI readings, institutional validation, and on-chain resilience suggests these altcoins are well-positioned to lead the next bull cycle. Investors with a medium-term horizon should monitor key support levels and on-chain metrics to time entries effectively.
