The popularity of tulip bulbs soon turned into a frenzy. Traders were willing to pay prices that exceeded the value of the most expensive canal house in Amsterdam for a single bulb (about 10.000 guilders). To compare: the average income of a Dutchman was about 150 guilders.
The tulip bubble reached her height in the winter of 1636-1637 and collapsed in February 1637, when a trader suddenly could not sell his goods. In the days that followed, the prices descended drastically: the tulip mania was over.
