A long-term cardano (ADA) investor recently made a costly mistake by exchanging $6.9 million worth of ADA for just $847,000 in USDA, Cardano’s dollar-pegged stablecoin. The swap occurred due to low liquidity in the ADA/USDA trading pool on Minswap, causing USDA’s price to spike temporarily. This incident highlights the risks of trading large amounts in illiquid markets—especially in the volatile world of cryptocurrencies. Below, we break down what happened, why it matters, and how traders can avoid similar pitfalls.
How Did a $6.9M ADA Trade Go So Wrong?
On November 18, 2025, a Cardano wallet holder attempted to swap 14.4 million ADA (worth $6.9 million at the time) for USDA, a stablecoin designed to maintain a 1:1 peg with the US dollar. However, the liquidity pool on Minswap—a decentralized exchange (DEX) on Cardano—only held $1.9 million in reserves. The massive sell order caused USDA’s price to surge, resulting in the trader receiving just $847,000 worth of USDA instead of the expected $6.9 million. Essentially, they lost over 88% of their intended trade value in seconds.
Why Did This Happen?
Liquidity is the lifeblood of any trading market. When a pool lacks sufficient depth, large orders can drastically skew prices. In this case, the ADA/USDA pool couldn’t absorb the sell pressure, causing USDA to temporarily decouple from its dollar peg. This phenomenon, known as "slippage," is common in low-liquidity DeFi markets but rarely to this extreme. As ZachXBT, the on-chain investigator who uncovered the trade, quipped: "Clown on-chain of the month—dude turned $6.9M into $847K because he didn’t check liquidity."
The Cost of Ignoring Liquidity
The trader’s loss wasn’t just bad luck—it was preventable. Here’s what went wrong:
- No Slippage Tolerance: The trader likely didn’t set a maximum slippage limit, allowing the trade to execute at wildly unfavorable rates.
- Illiquid Pool: The ADA/USDA pool had only $1.9M in liquidity, far below the $6.9M trade size.
- Stablecoin Volatility: USDA, like many algorithmic stablecoins, can temporarily lose its peg under extreme market conditions.
Could This Happen on Centralized Exchanges?
Unlikely. Centralized exchanges like BTCC or Binance typically have deeper liquidity and safeguards against such extreme slippage. However, DeFi’s permissionless nature means users must take extra precautions—like splitting large trades or using limit orders.
Lessons for Crypto Traders
This incident underscores three critical rules for trading cryptocurrencies:
- Check liquidity before executing large trades (use tools like CoinMarketCap or TradingView).
- Use limit orders to avoid slippage disasters.
- Test small amounts first—especially when dealing with newer or less-liquid assets.
Historical Context: Cardano’s Growth
The trader’s original ADA investment dates back five years, when ADA traded below $0.05. Their 14.4M ADA would’ve cost roughly $720,000 at the time—meaning they still turned a profit despite the mishap. Still, the lost potential ($6M+) stings.
FAQs: Cardano’s $6.9M Trade Debacle
What caused the massive loss in this ADA trade?
The trader swapped $6.9M worth of ADA into USDA on Minswap, but the liquidity pool was too shallow to handle the order without extreme price impact.
Could this happen with Bitcoin or Ethereum?
It’s less likely due to their deeper liquidity, but even major assets can experience slippage in illiquid markets or during extreme volatility.
How can I avoid this when trading crypto?
Always check liquidity, use limit orders, and consider splitting large trades into smaller chunks. Platforms like BTCC offer advanced order types to mitigate slippage.
