Think about the most valuable thing you own. Your wedding ring, perhaps, or your car. A collection of vintage memorabilia. Your crypto wallet. Would you ever entrust such a valuable possession to somebody else on your behalf? Would you ever leave it somewhere where it could be lost? No, of course not. Except it may well be that you already have. Right now, your most valuable possession may not be where you think it is. Arguably, you don’t really possess it at all.
