I'm curious to know, in the realm of cryptocurrency exchanges, how does Kraken stack up against KuCoin? Are there specific features or services that Kraken offers that KuCoin lacks, or vice versa? As a trader, I'm always looking for the most efficient and secure platform to manage my digital assets. Could you elaborate on the strengths and weaknesses of each exchange, and help me decide which one might be the better fit for my needs?
