Not your keys, not your coins gets repeated a lot, but I want to know where people here actually land on this in practice.

Do you keep everything in self-custody, split between an exchange and a hardware wallet, or mostly just leave things on an exchange because it is easier. If you do use a hardware wallet, which one, and would you actually recommend it to someone just getting started.

No judgment either way, just trying to get a real sense of how people here actually manage this.
