The Dutch Tulip Mania is one of the most famous bubbles of all time, for the scale of the bubble, the scale of the collapse, and probably including the seemingly obvious nature of the bubble considering the extremely limited functional utility of tulips. Bitcoin has now surpassed the multiples of value appreciation at the height of the Tulip Bubble (and by a wide margin). While this itself is not proof that Bitcoin is a bubble or that a collapse is imminent, it's worth considering if there's a lot more risk buying at this price (currently bouncing around $17,000) than anyone on these boards seems willing or able to recognize.

Thoughts?
The bitcoin is not a bubble, the bitcoin has still high value. The reason why the price of the bitcoin rapidly goes up because of the demand of the people to bitcoin that is continuing to increase. People are now aware to the benefits that they can earn from buying bitcoins.
