Sure thing! Using SQL UNION is a great way to merge multiple cryptocurrency tables into one. You can simply write a SELECT statement for each table you want to merge, and then use UNION to combine the results. Make sure that the columns in each SELECT statement have the same data types and are in the same order. This will ensure that the UNION operation works correctly. Happy merging!
