No Edge Without Information: An Empirical Study of Tradeability in Decentralized-Exchange-Only Cryptocurrencies
A new study finds that trading strategies based on price signals in decentralized exchanges (DEX) for small cryptocurrencies offer no real advantage. Analyzing nearly 5,000 DEX pairs across 27 blockchains, researchers show that common tactics like hedging, liquidity provision, and arbitrage perform no better than random chance. The only useful signal is a machine-learning model that predicts token crashes, but its impact is limited. The findings highlight the difficulty of gaining an edge in these volatile markets.
What it examines
This study examines whether traders can gain an advantage using price information in decentralized-exchange-only cryptocurrencies. Using data from 4,990 DEX pairs across 27 blockchains, it tests various trading strategies, accounting for transaction costs and survivorship bias, to see if any price-based edge exists.
What it concludes
The research finds no reliable trading edge from price information in these markets; most strategies lose money, even before costs. Only signals predicting which tokens will crash show some value. The study highlights survivorship bias as a major issue and suggests future research should focus on non-price signals and robust data handling.
Evidence objects
A sweeping study of nearly 5,000 DEX pairs across 27 blockchains finds that price-based trading strategies perform no better than random chance, often yielding worse results for small, obscure cryptocurrencies.

Surprisingly, even advanced tactics like hedging, liquidity provision, and arbitrage fail to generate consistent profits, with the markets negative drift, heavy tails, and volatility making gains elusive for long-only traders.
