Cryptography is the essential building block of independence for organizations on the Internet, just like armies are the essential building blocks of states because otherwise one state just takes over another. Julian Asange
The possibility to be anonymous or pseudonymous relies on you not revealing any identifying information about yourself in connection with the bitcoin addresses you use. If you post your bitcoin address on the web, then you’re associating that address and any transactions with it with the name you posted under. If you posted under a handle that you haven’t associated with your real identity, then you’re still pseudonymous. For greater privacy, it’s best to use bitcoin addresses only once. Satoshi Nakamoto
One of my favorite words is a French word: sousveillance. It is the opposite of surveillance. Surveillance means to look from above; sousveillance means to look from below. Andreas Antonopoulos
[Bitcoin is] worse than tulip bulbs. Jamie Dimon, CEO of JP Morgan
Stay away from it. It’s a mirage, basically. In terms of cryptocurrencies, generally, I can say almost with certainty that they will come to a bad ending. Warren Buffett
Bitcoin, and the ideas behind it, will be a disrupter to the traditional notions of currency. In the end, currency will be better for it. Edmund Moy
The computer can be used as a tool to liberate and protect people, rather than to control them. Hal Finney
The blockchain is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but virtually everything of value. Don and Alex Tapscott
Cryptography shifts the balance of power from those with a monopoly on violence to those who comprehend mathematics and security design. Jacob Appelbaum
This [Bitcoin] may be the purest form of democracy the world has ever known, and I — for one — am thrilled to be here to watch it unfold. Paco Ahlgren
Trusted third parties are security holes. Nick Szabo
Lots of people working in cryptography have no deep concern with real application issues. They are trying to discover things clever enough to write papers about. Whitfield Diffie
Bitcoin was created to serve a highly political intent, a free and uncensored network where all can participate with equal access. Amir Taaki
You should be taking this technology as seriously as you should have been taking the development of the Internet in the early 1990’s. Blythe Masters
I think the internet is going to be one of the major forces for reducing the role of government. The one thing that’s missing but that will soon be developed is a reliable e-cash. Milton Friedman
What affected me most profoundly was the realization that the sciences of cryptography and mathematics are very elegant, pure sciences. I found that the ends for which these pure sciences are used are less elegant. Jim Sanborn
Bitcoin is the currency of resistance. Max Keiser
The governments of the world have spent hundreds and hundreds of trillions of dollars bailing out a decaying, dickensian, outmoded system called banking when the solution to the future of finance is peer-to-peer. It’s going to be alternative currencies like Bitcoin and it’s not actually going to be a banking system as we had before 2008. Patrick Young
Hey, obviously this is a very interesting time to be in Bitcoin center now, but if you guys want to argue over whether this is reality or not, one Bitcoin will feed over 40 homeless people in Pensacola center now. If you guys want proof Bitcoin is real, send them to me, I’ll cash them out and feed homeless people. Jason King
The bitcoin world is this new ecosystem where it doesn’t cost that much to start a new Bitcoin company, it doesn’t cost much to start owning Bitcoin either, and it is a much more efficient way of moving money around the world. Tim Draper
