SInce gold and silver has a longer history and will always be money to many, in the in your hand idea, everyone should start with it.
Funny as I have been watching the netflix "The Last Kingdom" and they are talking about how many pieces of silver is required each episode. 400 Pieces seems to be their wealth factor.
But then when people are no longer able to get it (coming soon),they will dive into crypto's, to too must we. The recipe is sound... with two missing aspects even before gold and silver; food (water included), protection method, then silver/gold, crypto's. I place the crpto well above the metal miner stocks... although after secure why not try to tap into 3-4 digit gains.
