You are giving bad advice. Go to tulving.com or any physical seller to be cured of your ignorance.
I would not recommend buying metal from Tulving . Yes they have low prices but if you read the reviews people are having to wait months for delivery, the owner will not answer calls, and yells at customers. Mr. Tulving was in trouble with the FTC and went bankrupt.Buyer Beware.
You invest in fiat. I’ll stick to PMs. We’ll see what has value in 10 years.
