Generate a Scary Thought

People are always used to benchmarking history, sometimes against the internet bubble of 2000, and then noticing that Nvidia's price-to-earnings ratio isn't that high.

Then they benchmark against the subprime mortgage crisis, and it seems like the real estate market doesn't have a bubble, nor is there any leverage on leverage.

Is there a possibility that the bubble everyone is looking for is actually in the cryptocurrency space?

If the third bubble in America is indeed in the cryptocurrency space...

Then, are we currently in a post-bubble phase? Is the bubble yet to come? Or is it still fermenting?

If the bubble is yet to come, or if it is still fermenting, how big will this bubble become?
