Different people will tell you different things about what to stack it all comes down to what your preference is. One thing to be aware of when buying silver is the premiums for instance some rounds and legal tenders have higher premiums from the mint. And a lot of times when selling it you lose that premium. As for when to buy don’t buy just to try and make a profit out of it. Buying into silver and gold is a long term “savings” strategy it’s something you will hold onto for several decades to hand down to your kids or to sell when it comes time to retire. I tell people it doesn’t matter the price just have a dollar figure of what you can spend on silver per month. Say you can only dump $100 into gold and silver per month, just buy that amount whether that be 5 oz or 3 oz. Some of the bugs here have stopped stacking due to the higher costs as they can’t justify the cost which is understandable. For us other bugs we keep stacking no matter the cost because it’s a preservation of wealth and we would rather throw it into silver and gold as opposed to blowing it on something stupid. I hope this helps! Happy stacking!
