Could you elaborate on why Kraken is considered the best exchange in the cryptocurrency market? Are there specific features or services that set it apart from other platforms? What makes Kraken stand out in terms of security, user experience, and the range of cryptocurrencies available for trading? Additionally, how does it compare to other major exchanges in terms of fees, trading volume, and liquidity? I'm interested in hearing more about the advantages that Kraken offers to both individual and institutional investors.
