Cryptographical solutions might with great propriety be introduced into academies as the means of giving tone to the most important of the powers of the mind.

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.

But all those who used their knowledge in a bid to enact social change saw cryptography as a tool to enhance individual privacy and to shift power from big, central institutions to the human beings who live in their orbit.

Stay away from it. It’s a mirage, basically

If you care about liberty, the nonaggression principle, or economic freedom in general you should do everything you can to use Bitcoin as often as possible in your daily life.

Bitcoin is evil.

Bitcoin is a very exciting development, it might lead to a world currency. I think over the next decade it will grow to become one of the most important ways to pay for things and transfer assets.

Cryptography is typically bypassed, not penetrated.

Bitcoin seems to be a very promising idea. I like the idea of basing security on the assumption that the CPU power of honest participants outweighs that of the attacker. It is a very modern notion that exploits the power of the long tail.

We don’t really know how this coin is created. You can’t have a functional money without a basic transparency. Unless you are addicted to volatile trading for the sake of trading, stay away from the Bitcoin. Thankfully its plunge will be a salutary caution to most folks.

Bitcoin is the beginning of something great: a currency without a government, something necessary and imperative.

The cryptocurrency community hasn’t decided whether they want to be anarchist rebels or to replace the establishment.

So my view’s quite clear. I believe cryptocurrencies, Bitcoin is the first example, I believe they’re going to change the world.

Bitcoin gives us, for the first time, a way to transfer a unique piece of digital property, such that the transfer is guaranteed to be safe and secure, everyone knows that the transfer has taken place, and nobody can challenge the legitimacy of the transfer. The consequences of this breakthrough are hard to ove

Virtual Currencies may hold long-term promise, particularly if the innovations promote a faster, more secure and more efficient payment system.

It's money 2.0, a huge huge huge deal.

Bitcoin is just one example of something that uses a blockchain. Cryptocurrencies are just one example of decentralized technologies. And now that the Internet is big enough and diverse enough, I think we will see different flavors of decentralized technologies and blockchains. 

I think decentralized networks will be the next huge wave in technology. The blockchain allows our smart devices to speak to each other better and faster.

Cryptography has generated number theory, algebraic geometry over finite fields, algebra, combinatorics and computers.

If you guys want proof Bitcoin is real, send them to me, I’ll cash them out and feed homeless people.

Bitcoin promises to take at least some of that power away from governments and hand it to people. That alone augurs significant political, cultural, and economic clashes.

Not afraid of heights - afraid of widths.

Cryptography is the essential building block of independence for organisations on the Internet, just like armies are the essential building blocks of states, because otherwise one state just takes over another.

Blockchain is the tech. Bitcoin is merely the first mainstream manifestation of its potential.

Bitcoin is unstoppable.

The blockchain keeps everyone honest, and a whole layer of banking bureaucracy is removed, lowering costs.

Bitcoin was created to serve a highly political intent, a free and uncensored network where all can participate with equal access.

This 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.

Bitcoin is the currency of resistance.

It was the amateurs of cryptology who created the species. The professionals, who almost certainly surpassed them in cryptanalytic expertise, concentrated on down-to-earth problems of the systems that were then in use but are now outdated. The amateurs, unfettered to those realities, soared into the empyrean of theory.

I am very intrigued by Bitcoin. It has all the signs. Paradigm shift, hackers love it, yet it’s derided as a toy. Just like microcomputers.

With e-currency based on cryptographic proof, without the need to trust a third party middleman, money can be secure and transactions effortless.

Bitcoin may be the TCP/IP of money.

Bitcoin, and the ideas behind it, will be a disruptor to the traditional notions of currency. In the end, currency will be better for it.

Bitcoin is Money Over Internet Protocol.

One must acknowledge with cryptography no amount of violence will ever solve a math problem.

You can’t stop things like Bitcoin. It will be everywhere and the world will have to readjust. World governments will have to readjust

There are 3 eras of currency: Commodity based, politically based, and now, math based.

The governments of the world have spent 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.

The relative success of the Bitcoin proves that money first and foremost depends on trust. Neither gold nor bonds are needed to back up a currency.

Cryptocurrency Protocols Are Like Onions.

Right now Bitcoin feels like the Internet before the browser.

A cryptanalyst is a person who doesn’t like being called a hacker.

Every informed person needs to know about Bitcoin because it might be one of the world’s most important developments.

We have elected to put our money and faith in a mathematical framework that is free of politics and human error.

Bitcoin is a technological tour de force.

When cryptography is outlawed, only outlaws will have privacy.

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.

Bitcoin is Cash with Wings.
