Cardano's ADA is trading at $0.2147, up 1.08% in 24 hours and holding above the $0.2004 support level. Attention is also focused on the Ouroboros Leios protocol, whose first test reportedly increased Cardano's throughput capacity by 500%. Four more testing stages remain before the expected mainnet hard fork. Technical indicators place resistance between $0.23 and $0.2344, while a fall below $0.2004 could bring $0.1972 back into focus. Open interest rose near $580 million before easing to about $480 million on August 27. CoinCodex projects a gradual increase to $0.2177 by September 1, suggesting a mild upward drift rather than an immediate breakout.
