I agree, we are in an "everything bubble" and it's inevitable "pop" is due within two years or less. The effects will be global since the global financial systems are all intertwined.
I still think that "intrinsic value" for Bitcoin and other cryptos will require "use" ...if not in wide mainstream adoption, at least in a solid foundation niche market of traders and users.
More than a few people say that the bubble is popping right now. I tend to agree. Of course, the full pop and the total effects will become apparent over the coming months and years.
