Cardano’s DeFi Ecosystem Faces Scrutiny After Major Investor Loses Millions

The Cardano network finds itself at a critical juncture as conflicting signals emerge from major investors and technical indicators flash warning signs. Despite significant accumulation by large holders, a single disastrous transaction has raised fundamental questions about the maturity of Cardano's decentralized finance infrastructure.

Between November 6 and 10, 2025, Cardano's whale and shark wallets—those holding between 100,000 and 100 million ADA—engaged in their most aggressive buying spree since May 2025. This cohort accumulated approximately 348 million ADA tokens valued at over $200 million, prompted by ADA's decline below the $0.60 price level.

However, this accumulation tells only part of the story. Contradictory movements were observed as other major investors liquidated positions during the same period, with 4 million ADA exiting whale wallets in just one week. These opposing actions highlight the uncertainty currently surrounding Cardano's ecosystem.

Catastrophic Transaction Exposes Liquidity Limitations

On November 17, 2025, a long-dormant whale wallet attempted to swap 14.4 million ADA—then valued at approximately $6.9 million—for the USDA stablecoin. The result was devastating: insufficient liquidity in the trading pool triggered 87% slippage, effectively erasing nearly the entire position in seconds.

Despite receiving a clear "high price impact" warning on the decentralized exchange interface, the user proceeded with confirmation. This incident has ignited intense debate regarding the readiness of Cardano's DeFi infrastructure for mainstream adoption and casts doubt on the network's capability to function as a robust smart contract platform.

Should investors sell immediately? Or is it worth buying Cardano?

Technical Outlook Turns Bearish

Cardano's price action has deteriorated significantly since early November. After trading near $0.60, ADA declined to approximately $0.46 by November 17, hovering near its 52-week low. The breach of the crucial $0.50 support level proved particularly damaging to market sentiment.

Technical analysis presents a concerning picture. The formation of a "death cross"—where the 50-day moving average crosses below the 200-day moving average—suggests sustained downward pressure may continue. Market analysts have identified the next critical demand zones between $0.38 and $0.42. A breakdown below this support range could potentially drive prices as low as $0.25.

Development Progress and Regulatory Prospects

Despite current challenges, the Cardano ecosystem continues advancing its long-term vision. Several strategic initiatives were unveiled at the Cardano Summit 2025 in Berlin, including a partnership with stablecoin platform Brale to diversify stablecoin options and a new ecosystem fund with Draper Dragon to support growth and education. EMURGO's "Cardano Card" initiative aims to bridge the gap between digital assets and real-world applications.

Founder Charles Hoskinson's "RealFi" (Real World Finance) initiative targets ambitious goals, including reaching $1 billion in Total Value Locked (TVL) by 2026 through microfinance projects in Africa. Network upgrades including the Midnight mainnet, a privacy-focused sidechain, and the Ouroboros Leios enhancement are expected to substantially improve network throughput.

Regulatory developments offer additional optimism. Grayscale submitted an application for a spot Cardano ETF with the SEC in February 2025. Frederik Gregaard, CEO of the Cardano Foundation, confirmed active efforts toward U.S. regulatory approval. Market experts consider the likelihood of approval by late 2025 relatively high, potentially creating a catalyst for institutional investment inflows.
