Given the uncertainties but likely drop in price of silver over the next 12 months, I think the best approach is definitely that of not buying anything until silver reaches $10-12/oz. That way you can lower your cost average quite considerably (maybe to $15/oz), which is a price silver may actually reach again within this decade. If you buy at $15 you can only lower your cost average by a bit (maybe to $19-18. Still far too high.
So, wait before buying!
