This is a fine example of what I was saying, this is people cramming money into something with the hope of getting rich in a short period of time. People getting in knew it was a high risk gamble. Not to mention that the tech industry is now one of the biggest on the planet. Is it still a bubble?

Edit: attempt to add clarity.

The core of what I'm trying to say is almost any increasing asset is labelled as a bubble now days. I'm not denying that there aren't shady investments that appear and collapse all the time, some are enormous, like the tech bubble.

But it requires further classification. There are gambling bubbles built by thousands of agents where some have seen astronomical profit, but then there seems to be more stable "bubbles" like all of the bubbles mentioned in the article.

A bubble isn't a bubble, not without further clarification.
