Did you read the article you posted? Actual tulip mania, as described in the article, is much more similar to what is happening in bitcoin than the mythologized tulip mania.

Frantic speculation in a narrow space with the market eventually crashing when speculative buyers are no longer willing to bid up?

What was going for tulips is that they had an "expiration date" bitcoin will probably take longer because there's no such thing.

To me bitcoin lost its appeal after transaction fees became high. The value is ok, since you can still use fractions of it, but current transaction fees and time to wait for confirmation makes it unsuitable for daily use. So in my mind bitcoin already failed what it supposed to provide.

You're overstating your case. They just haven't been proven right.

In such a young, poorly understood, and speculative, environment it seems reasonable to suspect a bubble. 5 years doesn't prove or disprove anything.
