Looking back over history the bottom for silver is more like $5; not sure why $15 should be a bottom now when it hasn't stopped there in the past --even w/ inflation.
Yes, looks like a rough exponential decay back to $5 or maybe $10. But I have to believe there are going to be other exogenous events that will break the technical trends. Some of those events are downside, some are upside. I don’t see a lot of potential for downside events like tight money right now.
