We are still early. Here is an example of how people's ignorance is also a "protection". I put 1BTC in a wallet seed and hide it in a plastic recipient, behind that rock. The rock is located on a mountain trail that is quite transited by hikers. After almost 10 years that wallet is still there. I periodically check it in.

I am very confident in my capacity of hiding a seed in plain sight. I never lost any sat.
