    When using the WHERE NOT IN SQL clause in cryptocurrency databases, it is important to ensure that the list of values you are comparing against is accurate and up-to-date. This is especially crucial in the fast-paced world of cryptocurrency, where values can change rapidly. Additionally, make sure to optimize your query by using indexes on the columns involved in the comparison. This can significantly improve the performance of your query.

    Using WHERE NOT IN SQL clause in cryptocurrency databases can be tricky, but with the right approach, you can achieve accurate and efficient results. One best practice is to avoid using long lists of values in the NOT IN statement, as it can slow down the query. Instead, consider using a subquery to fetch the values dynamically. Another important aspect is to ensure that the columns being compared have the appropriate indexes, as this can greatly improve query performance.
