  To filter out specific values in SQL queries for cryptocurrency prices, you can use the WHERE clause in your query. For example, if you want to retrieve data for Bitcoin, you can add 'WHERE cryptocurrency = 'Bitcoin'' to your query. This will only return rows where the cryptocurrency column has the value 'Bitcoin'. You can also use other comparison operators like '>', '<', '>=', '<=', or '!=' to filter out specific values based on their relationship with other values in the column.
