I think nostrademons was trying to make the point that Coinbase Custody has nothing to do with Coinbase. Even if Coinbase looks amateur, maybe Coinbase Custody and Gemini Custody are both equally professional.
Yes. Also, interestingly products made for the ultra wealthy are less professional than those for a consumer marketplace. I don't know any consumer website that could get away with a webpage that just says "Contact us for more information. 555-555-5555." But this is pretty common for products that target hedge funds and family offices. The real professionalism happens in the grooming that happens after that initial call, which is all person-to-person relationships.
