That is some serious stack. Answer to your question is not easy as it varies from country to country and individual to individual. So here's my thinking. If I were in countries such as India or China I would have a very high percentage of my net worth in gold and silver. This is because in those countries silver and gold are easily recognized as money and are considered generational wealth. I wouldn't invest all in those countries as the fixed income via bank deposits still is pretty lucrative at about 7% per annum.
I am in USA so my stacking calculations are different. I take one year of my living expenses then double it and that is the value of silver that I would like to stack. I take 1/50 of that and that is the value of gold I would like to stack. So if my annual living expenses are say $20,000, I would like to have $40,000 worth of silver and roughly $1000 worth of gold. The amount of ounces will vary based on your average price.
The reasoning for doubling is future inflation.
Once this is reached, then start paying off your debt and start diversifying into other asset classes such as cryptos and real estate (farmable). Once that is reached, go off-grid!
I don't stack silver to get rich but merely to maintain my lifestyle. To be honest, when SHTF in a real bad way, it is your skill set especially the ability to grow food is what is going to come in handy. Stocking of seeds, thus become more important than anything else.
@ajain , really appreciate your insight and plan. You are right about not stacking to get rich. I stack simply because I know it will hold its true value. Not the value compared to the dollar, as for this is not a true value of silver. And yes you gotta beable to take care of your self when the SHTF. thanks for the visit and comment. Keep stacking my friend.
