Cardano's price is gaining attention as it hovers around the $0.23 support level, with traders eyeing a potential rebound. The recent Hydra 1.3.0 upgrade has improved network efficiency by enhancing scaling capabilities and reducing transaction costs. This development, alongside a fresh buy signal from the TD Sequential indicator, suggests a possible upward movement for ADA, with key resistance levels at $0.32 and $0.37. The Hydra upgrade, a significant layer two solution, has addressed issues related to deposits and rollbacks, while also making error messages clearer. This has reduced the cost of opening Hydra heads by four times, encouraging more developer activity. Cardano's network has also surpassed 300,000 deployed scripts, indicating robust developer engagement and potential for increased use cases. These advancements contribute to the renewed market interest in Cardano.
