Bitcoin - The Currency of the Internet
A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.
No banks. No western union. Only bitcoin. They need more of us supplying locally right now. Time for a vacation to Greece bitcoin believers. Book your trips charge a slight markup on localbitcoins and pay for your trip! Everybody wins!

Many people in Greece are currently learning a difficult lesson about centralized currency. When a government entity can control your money, they have the ability to devalue it and block you from spending it. A lot of people are losing lots of money at a time in their life when they really need access to it. Everyone in the whole country is losing money, and it's a terrible thing for their economy. Bitcoin is currently a strong alternative to centralized currency. Governments can't print money, and they can't shut down nodes that are running Bitcoin. They can't implement capital controls on Bitcoin. At least, they can't right now. But that's because Bitcoin is decentralized, and because any random home computer is capable of running a Bitcoin node, and the machine doesn't need to be a dedicated Bitcoin machine. I'm now going to describe a potential dystopian future that I legitimately fear. Lets imagine that it becomes expensive to run a Bitcoin node. The average home user is no longer able to run a Bitcoin node because the block sizes and standard usage are just too large. Running a Bitcoin node requires a dedicated server, and the costs of doing so are multiple hundred dollars a year plus multiple hundred dollars of dedicated machine. At the same time, in an effort to save their own currency, a struggling country decides to outright ban bitcoin. When nodes are so expensive to run, there will only be a few entities actually running full nodes. Bitcoin companies will likely be running and sharing Bitcoin nodes. A few universities, and then a very few number of enthusiasts who really care about Bitcoin. Given that there are only a few thousand Bitcoin nodes running today, and everyone is suffering from diffusion of responsibility, it's pretty easy to imagine that in the future where Bitcoin nodes are literally hundreds of dollars to run, there will only be a few hundred nodes. A country trying to ban Bitcoin is going to have a much easier time doing so. They can find and shut down most of the nodes inside of the country, and they can block internet access (like the great firewall of china) to other Bitcoin nodes around the world. You can't run anonymous Bitcoin nodes anymore, because Tor is slow and can't keep up with XXMB block sizes. The average SPV node is unable to connect to the greater Bitcoin network inside of this country without special configuration. People who are skilled will be able to apply special configuration and get around the firewall. They will be okay. But that's not something my mother or father could figure out, and God help the rest of my extended family. This scenario gets substantially worse as you continue to increase the block size. If we end up with XXX MB blocks, such that running a node takes thousands of dollars per year to maintain, censorship and control over these nodes is going to be substantially easier, simply because it's difficult to hide such a powerful piece of hardware, and because so few people/entities will go through the trouble of actually running one. When we look at things like increasing the block size, we need to make sure that we aren't losing the forest for the trees. I don't want people to one day realize that a government is able control their access to Bitcoin simply because they wanted blocks to be big enough to keep up with Visa. If you need datacenters to run Bitcoin nodes, you've lost everything that made Bitcoin special in the first place. A handful of datacenters can be subject to government control. Thousands of globally distributed and partially or fully anonymous nodes cannot be subject to anonymous control. When you look at whether or not the block size should be increased, please consider this. Bitcoin is much more than a cool, technological way to pay for your lunch. It's a contingency plan for when your fiat starts falling apart, and your government starts mishandling your centralized money. Bitcoin needs to be cheap enough for any random person to run a full node. Bitcoin doesn't need to work on a phone, raspi, nor does it need to be a cheap thing, but it does need to be accessible on standard consumer hardware in emergency situations like the one that Greece is currently facing. Bitcoin needs to be able to tolerate adversarial governments, and decentralization is the best way we know to achieve that. Addtionally, Bitcoin needs to remain small enough to be run through Tor. Tor is slow and expensive, and I'm not sure on the exact numbers but 20mb blocks requires 90GB of downloading every month, something that would put a lot of strain on the Tor network. Unbounded block sizes are absolutely, completely unacceptable. Would Bitcoin be okay at 2mb blocks? Probably. 4mb blocks? Probably? 8mb? 8mb is where I start to get worried. 8mb is reasonable for people who live in a city and have good internet speeds. But a large portion of the world's population does not live in a city, and has to deal with very expensive internet that struggles to break the 20mbps point. They have bandwidth caps in the low hundreds of GB. And if they are using Bitcoin as a contingency plan, they'll likely have to download a large portion of the blockchain from scratch. It shouldn't take 2 months of bandwidth to download Bitcoin, but that's a potential problem when the block size starts to go up. As the block size debate continues, please remember the importance of decentralization. Remember Tor, and remember that large portions of the population don't have access to city internet. When you increase the block size, you EXCLUDE people from being able to run nodes, and while that doesn't change their daily interactions with Bitcoin, it does change their ability to use Bitcoin in emergency situations. My personal vote would be for 2mb or 4mb blocks, but nothing larger. I do think that Bitcoin + the Internet in general is at a point where we can tolerate a block size increase. But I do not think that 20mb is a reasonable number. The number of nodes will continue to fall sharply if we do that, and that dramatically hurts our ability to use Bitcoin in situations where our government is trying to control our money. It destroys Bitcoin's core purpose.
Twitter ChangeTip Campaign for Greece - #GreeceBitcoinDrop
Let's be generous and have a little fun on social media with ChangeTip. Step 1: Find some high-follower profiles of Greeks. A source I found: http://twitaholic.com/top100/followers/bylocation/Greece/ Step 2: Send tweets to them. I used the following: "Banks frozen in Greece? Try Bitcoin instead... here is $5 @Desp1naVandi $5 @ChangeTip #GreeceBitcoinDrop #grexit #euro #eurozone" Step 3: Save the world! (nothing wrong with a little hyperbole) Remember that any tips you send which don't get collected will return to your account after a while (a month I think?) ProTip: Don't send anything less than $1 because then it's just annoying. Best to send $5 or $10 tips. Not sure who started this FYI - I've seen @BarrySilbert, @theuncoder, and @flix1 participating

These are emails sent between Stratfor employees. Email-ID 5473333 Date 2011-10-19 21:55:32 From [email protected] To [email protected] Bitcoin does provide a more discreet form of a transaction. Transactions can be tracked but bitcoin's transactions do not possess identifying information without a private key. Better to use cash, but better to use bitcoin than any common form of electronic transfers.

Even if there were a way to use Silk Road just as a payment method as opposed to a shipment method (assuming you could get the drugs to your customer some other way), drug dealers looking to move any amount would be better off not creating an electronic record of their cash transactions. I also think the article does a good job of explaning the anarchist/libertarian roots of the bitcoin movement. I think that this stuff can and will be used to facilitate a healthy amount of unofficial economic transactions. This idea sort of came up in a discussion Kevin started a few weeks back about alternative currencies in Greece. Bitcoin could become one alternative among many.

A non-profit looking to build out bitcoin infrastructure in order to help guide countries in a transition from fiat currency to bitcoin.
Hello all. I think that what is happening in Greece right now is a perfect indicator of the pitfalls of fiat currency. https://en.wikipedia.org/wiki/Fiat_money Fiat currency is inextricably linked to politics and is being used as a way to bully smaller countries into submission. At its core, fiat currency, like any currency is only worth something because people are willing to put their faith behind it. Money is a social fact. https://en.wikipedia.org/wiki/Social_fact But because individual countries are able to control fiat currency by selectively printing out, or buying back money in order to control inflation, individual countries, or groups of countries can bully others into submission forcing the Greek populace to pay for mistakes that are not theirs. https://en.wikipedia.org/wiki/Monetary_hegemony Its time to separate money from politics, and instead connect money with the true source of its power, the people themselves. Already we are seeing a sharp rise in Greeks buying bitcoin in order to save their assets, but the problem of their not being a built infrastructure in which people can spend them is one of the major things hindering the adoption of bitcoin. http://money.cnn.com/2015/06/29/technology/greece-bitcoin/ What I am suggesting is the formation of a non-profit that helps educate and build out bitcoin infrastructure in the places that need it the most. I think that reddit could be a good forum where people could freely discuss the various things that would need to happen to make this a reality. "Bitcoin is the currency of the Internet: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. As such, it is more resistant to wild inflation and corrupt banks. With Bitcoin, you can be your own bank." Bitcoin exchanges already exist. Services like https://www.kraken.com/https://cex.io/https://btc-e.com/https://www.coinbase.com/https://www.cryptsy.com/https://www.bitstamp.net/https://www.bitfinex.com/https://www.btcchina.com/#/ have already taken the first steps. Lets work together to try to make this distributed, worldwide, decentralized digital crypto-currency the new "gold standard". Lets take back our money. Who's with me? *edit Of course there are already people doing this! The main problem is connecting them all together and aggressively pursuing these goals! http://bitcoinfoundation.org/https://www.indiegogo.com/explore?utf8=%E2%9C%93&filter_title=bitcoin#/search
