The economy is up, the broad markets are up and many investors are happy about how the end of 2017 is wrapping up. However, other investments have done so well that the growth in the markets looks unimpressive in comparison. Bitcoin, for example, is up a little more than 1,400 percent in 2017. By any standards, that’s impressive. Each bitcoin is worth about $16,432. With such astronomical growth, it’s dizzying to think that the currency was only begun in 2009.
