Keeping the private key somewhere never connected to the internet
The key is held on a dedicated device or on paper, cut off from any network. With no route in from outside, there is nothing for an attacker to reach. The trade is that losing or breaking the device loses the key, and there is no way back.
One device can hold the keys to 10 or more different crypto assets.
