It does to me as well, except when you ignore the price and look at the behavior around the logarithm fit. 

When I first heard about it, it was $12.  (friend buying on silk road)

Then I registered to buy on MtGox one day before it got hacked (funds had not been deposited yet) at $150

I started buying when it passed the price of gold ~ 1200 -- when I realized that was 100x what I first heard about it at, I knew normal price thinking doesn't apply....

Oh, and the Tulip mania lasted about a year
