I agree with you. For me, gold and silver are safer than bank deposits because they are stable and are valuable asset.
Gold, platinum, and silver will live always, and nothing will happen to them. Yes, they can be volatile but it does not mean a lot. Finally, they will be valuable. You can buy any things on it. Crypto is a bit different.
I am very sceptical about platinum (and palladium) because they are NOT historically motivated, like gold and silver has been for millennia. Rather than historical conditions, it is modern use cases that drive their price. I believe that crypto is a little bit similar to platinum in that regard (it is new and it is hard to predict its behaviour long scale).
