In my opinion, Bitcoin is best suited to a macro economic purpose such as this, because it is the most secure network in the world, but very ill suited for processing large volumes of transactions. Since some people only live on a few dollars a month, they can't afford to pay a few dollars to make a Bitcoin transaction. For this reason, Bitcoin can not become a global currency for everyone.
I do agree that there are certain segments of the industry that are undergoing a bubble, primarily in the areas where there is easy money to be had.

For anyone who might be thinking about comparing Bitcoin's price spike now, to what happened in 2013; which was followed by a near 2 year correction - do not forget that the price spike back then was an insider job, caused by two bots on the now defunct exchange Mt Gox.

Who knows what began driving this most recent price spike in Bitcoin, but I have a suspicion that something reminiscent of Mt Gox is going on again.

At any rate, my gut feeling is that Bitcoin will undergo another correction period beginning at some point in the near future, then will continue on to reach unthinkable prices. A big problem I see in this for the average person is that when BTC hyperdeflation intensifies, existing Bitcoin holders won't be able to get rid of their Bitcoin, simply because it is too expensive to move.
First of all, none of those academics are 'experts' outside of how to study the manipulation of markets for personal and megalomaniacal gain. I could hardly take Paul Krugman, Joseph Stiglitz, or any central banker's opinion seriously -- it is like asking. Even the Central Bank in New Zealand said "it's blatantly a bubble". Everybody is saying it might be a bubble, and yet everybody still wants to buy it. We should clearly put our faith in the Keynesian command-and-control style economists who have been wrong every time.
That Amazon bubble tho...
