4 Altcoins Flashing Major Sell Signals: What Happens if Key Supports Break?

The cryptocurrency market is currently navigating a period of intense volatility and bearish sentiment. After a promising start to the year, a combination of macro pressure—including hawkish signals from the Federal Reserve and geopolitical tensions—has pushed major assets to critical technical thresholds.

As of late February 2026, several top-tier altcoins are "flashing" sell signals that traders cannot afford to ignore. These signals often manifest when an asset struggles to reclaim moving averages or, more dangerously, when it hovers just above a multi-month support line. If these floors give way, the resulting "liquidation cascade" could lead to double-digit percentage drops.'

Will Crypto Crash lower?

Are these altcoins ready to dump? Technical indicators across the board suggest that if Bitcoin fails to hold $62,000, the broader altcoin market, including Ethereum ($ETH) and Solana ($SOL), is positioned for a significant retracement.

1. Ethereum (ETH): Risks Under $1,790

Ethereum has entered what analysts call a "bearish continuation pattern." Despite its fundamental strengths in DeFi and NFTs, Ether is currently underperforming against Bitcoin.

• The Sell Signal: A daily close below $1,790.
• The Analysis: According to recent on-chain data, founder-led selling and ETF outflows have dampened buy-side pressure. If $1,790 breaks, the next major structural support sits significantly lower at $1,500.

2. XRP: The $1.28 Critical Pivot

XRP has shown relative strength due to regulatory optimism, but the technicals are starting to sour as the broader market drags it down.

• The Sell Signal: Dropping below $1.28.
• The Context: XRP is currently consolidating losses below its 100-hourly Simple Moving Average. A failure to hold the $1.28–$1.30 support zone could invalidate the recent bullish "Clarity Act" narrative, sending the price toward $1.12.

3. Solana (SOL): Testing the $71 Floor

Solana has been one of the most volatile assets in early 2026. After a massive run, it is now testing the resolve of "diamond hand" investors.

• The Sell Signal: Sustained trading below $71.
• The Outlook: As reported by Cointelegraph, a Head-and-Shoulders pattern has appeared on the weekly charts. A decisive break below the $71–$74 support area could trigger a plunge toward $48–$50, erasing months of gains.

4. Cardano (ADA): Stagnation Near $0.24

Cardano continues to struggle with liquidity and a lack of aggressive growth compared to its peers. It is currently "trapped" beneath heavy resistance.

• The Sell Signal: Settlement below $0.24.
• The Warning: ADA is currently trading near $0.26. If it loses the $0.24 support, it enters a "no-man's land" where historical buy orders are thin. Many whales are reportedly rotating out of ADA into newer DeFi protocols.
