I have quite a bit more to buy and put into self custody yet. What's the hold up? Because I'm not comfortable with my opsec yet. I'm building it out. Sometimes I think, "Come on, man. Just get it in cold storage and be done with it," but I remind myself that opsec follows the weakest link rule and I haven't inspected the entire chain yet.
One flaw is all it takes and you wake up one day with nothing.
Patience and diligence.
