I personally think that decentralised peer to peer cryptocurrencies like Bitcoin have a very bright long term future. The linked documentary is well worth fifty minutes of your time in my honest opinion. As the film helps to show why cryptocurrencies are such a game changing paradigm shift and are actually vitally needed.
What is Bitcoin?
Sure—You know the history. As it spread from the geeky crypto community, Bitcoin sparked investor frenzy. Its “value” was driven by the confidence of early adopters that they hitched a ride on an early train, rather than commercial adoption. But, just like those zealous investors, you realize that it may ultimately reduce the costs of online commerce, if and when if it becomes widely accepted.
But what is Bitcoin, really? To what class of instruments does it belong?
• Ardent detractors see a sham: A pyramid scheme with no durable value; a house of cards waiting to tumble. This is the position of J.D, an IRS auditor who consults to The Cryptocurrency Standards Association. As devil’s advocate, he keeps us grounded.
The National Security Agency knows Edward Snowden disclosed many of its innermost secrets when he revealed how aggressive its surveillance tactics are. What it doesn’t know is just how much information the whistleblower took with him when he left.
For all of its ability to track our telecommunications, the NSA seemingly has little clue exactly what documents, or even how many documents, Snowden gave to the media. Like most large organizations, the NSA had tools in place to track who accessed what data and when. But Snowden, a system administrator, apparently was able to cover his tracks by deleting or modifying the log files that tracked that access. Read more
Bitcoin survived a wild youth marked by drug trafficking, money laundering, theft, bankruptcy, and political spats. Now, the digital currency is getting cleaned up and heading to grad school.
A fledgling project at the Massachusetts Institute of Technology Media Lab is offering researchers and software developers a quiet home to work on bitcoin’s core technology, a computer science breakthrough that lets people trade money securely without paying a middleman. Read more
Cryptocurrency aficionados have been discussing Bitcoin limitations ever since the blockchain buzz hit the street. Geeks toss around ideas for clearing transactions faster, resisting potential attacks, rewarding miners after the last coin is mined, and supporting anonymity (or the opposite—if you lean toward the 
dark side). There are many areas in which Bitcoin could be improved, or made more conducive to one camp or another.
Distinguished Penn State professor, John Carroll, believes that Bitcoin may eventually be marginalized due to its early arrival. He believes that its limitations will eventually be overcome by newer “altcoins”, presumably with improved mechanisms.
So, does progress in any of these areas threaten the reigning champ? It’s unlikely…
More than any other individual, Andreas Antonopoulos is the face of Bitcoin. We discussed this very issue in the outer lobby of the MIT Bitcoin Expo at which he was keynote speaker (March 2015). Then, we discussed it again, when I hosted his presentation at The Bitcoin Event in New York (also in March). He clearly and succinctly explained to me why it is unlikely that an altcoin will replace Bitcoin as the dominant—and eventually surviving—cryptocurrency…

“When you combine Bitcoin’s global scope, its extreme divisibility and its ability to verify transactions without third parties, you end up with a system where engaging in exchanges of economic value becomes nearly as friction-free as tweeting or texting.” Read more
“But if Bitcoin is ever used by enough people so that blocks are 90 or even 100 percent full, the network could become congested to the point of unusability. The solution, Andresen believes, is to increase the size of each block to 20 megabytes by 2016. How? By changing Bitcoin’s underlying protocol and splitting the blockchain into two different versions—one using 1 megabyte blocks and the other using 20 megabyte blocks.” Read more

Nathaniel Popper’s new book, Digital Gold, is as close as you can get to being the definitive account of the history of Bitcoin. As its subtitle proclaims, the book tells the story of the “misfits” (the first generation of hacker-libertarians) and “millionaires” (the second generation of Silicon Valley venture capitalists) who were responsible for building Bitcoin, mining it, hyping it, and, in at least some cases, getting rich off it.
The tale is selective, of course: Not everybody involved with Bitcoin talked to Popper, and the identity of Bitcoin’s inventor, Satoshi Nakamoto, remains a mystery. But Popper did talk to most of the important people in the cryptocurrency crowd, and he tells me that he put real effort into trying “to find a woman who was involved in some substantive way.” Read more
