The comments on the BBC news article are hilarious.
People still talking about Tulips.

Always the tulips, never the Weimar republic.
(The tulips were cause by government interference in financial systems for anyone who doesn't know by now)
I may have history incorrect, but I think the tulips happened over a single year. Maybe 2 years. That's it. Not 12 years, and not through 3 halving cycles.
