I'm new to stacking. As a matter of fact I just made my first purchase this week and now that I have made the plunge I find myself with more questions than I had before. I am not a volume buyer. I make small purchases as my budget allows but I know eventually I will accumulate enough 1 oz. coins/ bars that I will have to move into larger bullion sizes. At what ratio should you think about moving from ounces to 10 oz. and so on. I would like to stay fairly liquid in small rounds/bars for any potential economic problems but still want to have larger amounts as part of my long term investing.
