How long are you willing to wait for returns?

If you want annual returns, you gotta go with Index Funds.

But, to absolutely get that 7.1% annual return (as the brochure says is expected/possible) you'd have to have your money invested over the same duration of 113 years (1900-2013). That's not to say that you can't achieve those returns, reliably, in shorter time frames it just means that their analysis is made more sound based on the total volume of years they include in the calculation. If you invest for fewer years you increase the risk that your avg. annual return will be something other than 7.1%.

If you're willing to wait for your return, go with bitcoion...because if it goes, it's gonna go far. You just can't consider it a reliable investment yet.
