I would suggest buying gold and then just burying it in the yard.
As, before we get to a good point for selling gold, there is going to be all kinds of world upheavals.
So, just bury it and forget it.
Because, this time they are really going to confiscate gold, not by decreeing that you should turn it in. No, it will be a sign that you are a terrorist, and since you are a terrorist, all your possessions (the gold) will be seized.
