The dotcom bubble had some sense in it: maybe pets.com was massively overvalued, but selling pet food online is a real business, and the web has changed many things. Cryptocoin scene, in contrast, is based on at best utterly misguided ideas (that markets can exist without regulation—in fact regulation creates markets), at worst it's fraud. Most of the time I'd say it's just plain fraud: "here, give us money and we'll give you... numbers! special numbers!"
