Tulip mania was a bubble in a time where the Dutch really really loved their tulips but the prices got so ridiculous that everyone tried selling, instead of everyone trying to buy them.

Beanie babies was also a bubble, 2008 was also a real estate bubble. The difference between all of these and BTC is that the tulips, the houses, the stuffed toys, all were in unlimited supply and they didn't serve an actual purpose. Yes, BTC is exciting and people might rush into it but it actually serves a very good and targeted purpose. It's not just a pretty flower.
