I have a theory to share: Perhaps high-profile executives are speaking of doom and tulip gloom in bitcoins near future only to permanently carve their names into bitcoins (likely incredibly prospers) history.
Mark Cuban:
Let's take Mark Cuban for example. Cuban claimed Bitcoin was a sham. Through a series of tweets, he claimed that Bitcoin was merely a bubble. Shortly there after, his comments eternally and immutably carved "the Cuban Collapse" into Bitcoin's price chart.
Since his initial pessimistic statement, Mark Cuban completely reversed his thoughts on digital currencies. Cuban went on to lead Unikrn's ICO (an E-Sport digital currency), invest in 1Confirmation (a digital currency investment fund), and work to integrate blockchain into his SnapChat competitor, Cyber Dust.
Jamie Dimon:
Today, Jamie Dimon, the CEO of JPMorgan Chase, claimed bitcoin was a "fraud". Now, this bold claim falls in line with similar claims Jamie made in November of 2015 when Bitcoin was valued at just around $400 when he stated cryptocurrencies could not last.
If one gives Jamie the benefit of the doubt, we can assume that he would recognize the fact that such brash, redundant claims look foolish in the face of the greater than 1,000% increase Bitcoin has made since he first decided to cast his judgements.
So why? why on earth? would Jamie make himself vulnerable to yet another humiliatingly inaccurate claim?...
To create "The Dimon Dip":
Immediately following Jaime Dimon's remarks, Bitcoin's value fell similarity to how it had when Mark Cuban had gone public with his "doubts" in digital currencies.
Conclusion:
In a matter of sentences, by simply utter a few public statements, these two men have not stopped, slowed, or at all truly marred Bitcoin's inevitably spectacular future. However, what they HAVE done, is forever etch their name into the history of the world's most revolutionary currency, Bitcoin.
So congratulations Mr. Dimon and Mr. Cuban, you have permanently and irreversibly become a part of Bitcoin.
And Jamie, I look forward to your impending blockchain investments ;).
