People were buying tulips because it was a sign of wealth and taste and a beautiful rare object to display, just like art. People were speculating on those, just like art. But when people do so with Art and pay millions, nobody bats an eye.
Bitcoin (and other commodities) might have another underlying reason for why people give them value and decide to speculate on them (just like, say, Wall Street speculating on cattle futures).
So yeah, maybe some Tulips were sold the price of houses - but it sounds normal when someone spends millions on a painting.
I'm defending any point, just saying I think it's interesting to read this, I never heard before that people were mostly buying tulips because of their symbols, not just for pure speculation.
