The article is crap. How can some idiot compare Bitcoins to Tulips.

Tulips mania was isolated to Denmark and surrounding areas/countries.
It was treated more like art...people collected Tulips.
Though Tulips were exchanged for money, it really wasn't used like currency.

The psychological hype may have been similar, but Tulips were bound to fail.

Bitcoin and other crypto currencies however, are used as a store of value and exchange for goods and services.  An alternative to FIAT dollar, like the American "toilet paper" dollar, that has a mad man at the printing presses.

The psychology, behind Bitcoin is hype to some level, but also of fear and protection of a portion of ones capital in case the "SH!T hits the fan". Similar to gold.

Anyway, my 2 cents.
