Via email from Tom McClellan, please consider Gold's 8-Year Cycle.

We are now entering the upward phase of gold's 8-year cycle, and that should bring some fun gains. And this comes at a time when gold has not been getting much of investors' attention. If gold stays flat for a year, and Bitcoin twinkles to get all of the attention, speculators eventually drift away from gold. That sets up a great opportunity for gold to start getting more attention, and more money thrown its way.

As with most market cycles, gold's 8-year cycle is measured bottom-to-bottom. But there is more to it than just that 8-year period between major bottoms. It typically sees a 3-year upward phase, which is where most of the big gains are seen. Then the 5-year downward phase actually has a 3-wave process of going down.
