I like the Kraken arguments based on the existing laws that were established for stocks, bond, and other financial assets subject to SEC regulations.
I am skeptic whether the SEC have good knowledge about cryptocurrency, and each time I read about them clamping down on CEX/Dex exchanges.
Based on some coins/token they had categorized as security, and on this arguments that were actually established to guide stocks, bonds, and others, unfortunately, many of the SEC lawsuit has not gone their favour, and I keep wondering if SEC chairman and his team are just chasing crypto exchanges for their selfish benefits or they are politically motivated. I think they have not been fair on their pursuit to regulate the cryptocurrency economy.
