In what way is the chart helpful? The article is from 2017:

> Then again, there already has been deflation from the peak of a little more than 19,900 to 17,600 dollars per Bitcoin. But nobody knows if the puncture will let the balloon slowly deflate or it will rip it apart, crash landing the Bitcoin.

Well, neither. Bitcoin went to 60k or something.

Did the tulip mania also have so many peaks?

Years ago I wanted to publish a tulip:btc exchange rate, but the auction house in Amsterdam does not publish the daily price for free.
