How do I search cryptocurrencies using -F & -E?
As a keen investor in the cryptocurrency market, I'm always looking for efficient ways to search and filter through the vast array of digital currencies. Could you elaborate on how I can utilize the `-F` and `-E` flags to enhance my searches? I'm particularly interested in understanding how these flags work, what type of information they can filter, and whether they're supported by popular cryptocurrency search engines or APIs. Additionally, I'd appreciate any suggestions or best practices you have for effectively searching and filtering cryptocurrencies based on specific criteria.
