I wouldn’t want to be anywhere near a custody arrangement like that. You’d have to imagine that if someone wants those keys they’re going to go a LONG way to get them given what’s at stake, literal nation state level wealth on the line. I assume there are already intelligence operatives working their way in to Coinbase to set this up. IBIT already has $20B+ - imagine what an activist group could do with that kind of uncensorable capital..
