> Does that mean we should shun and shame this new technology?
You're inventing a straw-man. It's not the technology that is being primarily shunned or shamed in this thread. It wasn't the technology being shamed during the most extreme quarters of the dotcom bubble either.
It's the extreme valuations, backed with no products at all, that is being ridiculed. Properly so.
Those valuations don't really mean that much. It's simply number_of_coins * price. Saying it's worth $1bn does not mean you can take all of those coins and turn them in for $1bn. If you owned a large portion of the coins and tried to liquidate them at that price, the price would quickly drop.
Does that mean we should shun and shame this new technology? Doing so would seem—to me at least—to be something that's really not in the spirit of HN.
