  Optimizing SQL UNION queries when working with cryptocurrency data can be a challenging task. However, there are several techniques that can help improve query performance. One approach is to use UNION ALL instead of UNION, as it eliminates the need for duplicate removal and can significantly improve query execution time. Another strategy is to carefully analyze and optimize the underlying database schema, ensuring that it is properly indexed and normalized. Additionally, caching frequently accessed data and using query optimization tools can further enhance query performance. Overall, it's important to regularly review and fine-tune your SQL UNION queries to ensure optimal performance.
