  Handling not equal comparisons in SQL statements for cryptocurrency data analysis requires some best practices to ensure accurate and efficient results. One approach is to use the '!=' operator to represent not equal. For example, if you want to select all records where the price is not equal to a specific value, you can use 'SELECT * FROM table WHERE price != 100'. Another useful technique is to use the 'IS NOT NULL' operator to check for non-null values. This can be helpful when filtering out records with missing data. For instance, 'SELECT * FROM table WHERE price IS NOT NULL' will retrieve all records where the price column is not null. Following these practices will help you handle not equal comparisons effectively in your SQL statements for cryptocurrency data analysis.
