Bitcoin A Bubble, But Long Term Value?

 | Nov 30, 2017 12:44AM ET

As I write, the price of bitcoin just smashed through US$10,000, and has pushed up through US$11,000.

That’s amazing when you consider it was just US$300 in January 2015. At the beginning of 2017, it was just under US$1,000.

And it’s not only bitcoin that’s on a tear. Dozens of crypto tokens are up hundreds of percent over the past few weeks.

Now, we’re seeing a lot of self-congratulatory backslapping from crypto investors . Folks talking victory laps, bragging about their returns. Hubris.

This makes me uncomfortable.

It’s easy to feel like a “genius” in a raging bull market. But make no mistake, markets don’t go parabolic forever…

Just take a look at the chart below that shows the crypto market (excluding bitcoin) over the last year.

And now look at the gains in just one week. 45 percent. In a week. This is not sustainable.
