In cryptocurrency, you can use a multi-signature account to define your own security setup.
For example, even a 2-of-2 setup with a trusted authority like a bank is straight-forward improvement in security over the conventional bank system.
You can go further, for example consider a 3-of-5 setup with 2 keys in security deposit boxes, 1 key on a laptop, 1 key on a phone, and 1 key on a hardware token. You can set the hardware token to erase its keys when the wrong pin is entered, making it pretty rubber hose proof.
