Honestly, who really thinks this space is in a Bubble?

Is it people who have an interest in seeing it fail or people who want to see it succeed?

Is it people whos businesses are threatened or people who want a lower entry point?

If you look at the History of "Bubbles" we are not even close to the past examples throughout history of a "Bubble" in this space. 

The United States Of Americas 20 Trillion Dollar Debt is a Bubble.
The Japan 26 Trillion Assest Bubble was a "Bubble"
The 8 Trillion US Great Recession was a "Bubble"
 The 7 Trillion Dotcom was a "Bubble"
 
The current crypto currency Market Cap: $350,891,931,502

Don't let these Bigots lie to you & push their own agenda. 

We should not forget that Bitcoin was created in 2009, Ethereum in 2015, the Blockchain industry is still in its infancy. Mass adoption is, therefore, yet to take place. If you think of market penetration now, some estimates indicate there are between three to five million cryptocurrency users, which represents 0.14%-0.24% of the 2.1 billion people in the world between 14 and 65 who have internet access. Imagine the space to grow here.
