Let me start with some disclaimers: The point of this blog post is not to convince you to use bitcoin, but to clarify the difference between a risky start-up currency and a scam/ponzi scheme/pyramid scheme. I own a bunch of bitcoins, I mine for bitcoins, and if something causes the value of bitcoins to drop to zero (from government crackdown to defects in the system), you could lose any money you’ve invested in bitcoins.

That does not make them a scam.

ADDENDUM #4 Let’s define these words, shall we? I googled them:

scam: A dishonest scheme; a fraud

ponzi scheme: A form of fraud in which belief in the success of a nonexistent enterprise is fostered by the payment of quick returns to the first investors from money invested by later investors

pyramid scheme: A form of investment (illegal in the US and elsewhere) in which each paying participant recruits two further participants, with returns being given to early participants using money contributed by later ones

Addressing each briefly: Bitcoin is a scam – Everything about bitcoin is out in the open, unless someone is telling you it will give you a guaranteed return on investment. Bruce Wagner doesn’t count, he just gets excited. Bitcoin is a p2p ponzi scheme – The bitcoin enterprise is existent, and there’s no payout guaranteed by the system, fed by later investors’ money. It’s a commodity and the value may fluctuate, and who knows whether you or someone else will make gains. Bitcoin is a pyramid scheme – Basically the same as a ponzi scheme, except there’s not even any pretension of a real enterprise (like Madoff’s fake investment fund). Again, bitcoin doesn’t require you to go recruit people and get paid a cut of what they invest in return. Bitcoin is a real thing and that’s easy to verify.

See, bitcoin are designed to be a peer-to-peer digital currency, currently functioning as an easily-transferable commodity. The bitcoin system has a few key characteristics:

• There is a fixed and gradually decreasing rate of monetary inflation (money creation)
• It is very difficult (and rapidly getting more difficult) to make fraudulent bitcoin payments
• It is cheap and very easy to send bitcoins anywhere in the world, in seconds
• If used properly, the system can be anonymous, allowing financial freedom analogous to freedom of speech. An example of where this is useful would be the financial choke-off of Wikileaks.

The system is secured by people doing a certain kind of work with their computers. This work has been called a complete waste of electricity, but it’s not. It secures the network from fraud. (Think for example on how much money and energy is spent securing banks. Is bitcoin’s energy use larger?) As an incentive, the people doing this work (mining) are paid some bitcoins. However, the rate of total payouts is maintained approximately constant by the network, so the more people mine, the more difficult mining becomes. This system of rewards and difficulty is the first example I’ll give of the clever incentives built into bitcoin.

Let me explain.

I heard about bitcoin, investigated it, saw that it had potential. I bought some and set up some hardware to mine for bitcoins. As difficulty went up, along with the value of bitcoins, I realized it was worth my while to keep investing in mining hardware, electricity to power it, etc, so I did, as did others. This made the network more secure, and drove difficulty up again. People became more confident in the system, and more people heard about it, driving up prices. This caused people to bring more mining hardware online, security and difficulty of mining increased, etc. This continues to happen at an exponential rate. At one time there was a risk that someone with a botnet could easily overtake the network. That risk is now minimal and getting (exponentially) smaller every day, especially as bitcoin miners are eagerly buying up the world’s supply of the most efficient mining hardware.

This mining work is essential to the security and functionality of bitcoin. The people putting in the effort to mine are being paid by the network, yes, and this has been criticized as a scheme to make early adopters rich. However, if bitcoin never catches on for anything, the early adopters will be out all of this time, effort, and some of the money they spent on mining hardware. They are taking a risk based on their understanding of the technology and their ability to harness it for return on investment. If this risk pays off they will make a profit. This is the essence of entrepreneurship.

We are seeing a lot of ‘sour-grapes’ griping from people who dismissed bitcoin early on, didn’t buy in, and missed some early appreciation of the currency. You hear similar things from people who failed to buy a stock that subsequently skyrocketed.

There’s a second component to the idea that bitcoins (which have a fixed supply) will become more valuable as more people want them. More people will only want them if bitcoin is useful, and has a community around it, especially a community of merchants willing to sell goods and service for bitcoin. By giving the early adopters bitcoins when they are not yet very valuable, they are given an incentive to build a community and a market around bitcoins. There is no company behind bitcoins. There’s no marketing budget. There are no representatives to go give sales pitches to merchants. There is only the community of bitcoin users. Therefore, for bitcoins to get off the ground, it’s actually very important that the early adopters have a strong incentive to evangelize bitcoin. And really, there’s nothing wrong with them (us, I guess) doing so. We bought in, spent time analyzing, discussing, and running the bitcoin network early on. We think bitcoin is a worthwhile project. We recognize that if we don’t evangelize bitcoin, it’ll fall by the wayside. The value of our bitcoins will be reduced. Most importantly, a technology that we find inspiring, interesting, and useful may become a simple endnote in the history of the Internet. So when you hear bitcoin users extolling the virtues of the project, you can bet your ass it’s because we want the value to grow. Why wouldn’t we? But it’s not so we can cash all of our bitcoins out and leave you holding the bag. It’s so the whole community can benefit as bitcoin grows, and you (the new user) along with it.

One hears complaints about speculators affecting market prices. It’s true that some speculators bought when prices were low, and will sell when prices are high, taking their money and leaving. The speculators are not doing anything bad, however – speculation is something that occurs whenever you have a free market. Speculators provide a useful function in helping to set appropriate prices, by incorporating future expectations about the value of an asset. (We’ll leave further discussion of the utility of speculation, if needed, to a future post.) In the minds of many, the price is not high at all, compared to what it will be if bitcoin succeeds in gaining traction. This is what speculators are betting on, and pricing into the market.

The incentives are working. Bitcoin users are collecting on the forums to set up bounties for useful things (like Android apps — I paid 1000 BTC for something that met my requirements). Bitcoin users invest time and effort in developing tools for other users of the network (see bitcoincharts, bitcoin monitor, bitcoin block explorer). We hang out in #bitcoin-dev and #bitcoin-otc on freenode IRC and explain to newbies how to get miners up and running, how to back up their bitcoin wallets, and answer their questions on the (admittedly) complex system that makes bitcoin work. We help out merchants with information on how to set up for accepting bitcoins for their products and services, write documentation on various aspects of bitcoin, and release open source code to make bitcoin integration easier.

That’s one other thing I want to say. Bitcoin is complicated. Taken alone, any one of its parts (fixed rate of inflation, ease of money transfer, potential for anonymity, proof-of-work and blockchain for peer-to-peer accounting, public key cryptography, SHA256 hashing to hit a target numeric threshold, etc) is not that novel or compelling. What makes bitcoin so cool is the combination of all of these parts into one system. It’s much easier to glance over bitcoin, say, “Oh, it’s just like (dead e-money project X), it’ll just flop”, and post, “bitcoin is a scam, LOL, maybe I can exchange my Flooz for them”, on Twitter than it is to write a long explanatory blog post like this one. Twitter and Facebook have trained us into a “too long; didn’t read” (tl;dr) mentality that doesn’t allow for nuanced dialog.

Finally, a comment on criticizing something before bothering to understand it. There are a lot of paranoid crypto geeks using Bitcoin. They have argued to death the security of the system on the bitcoin forums. Satoshi, the original developer of bitcoin, engaged in some discussion of the system on the cryptome mailing list (i.e. with the Secret Admirers for fellow Cryptonomicon fans) before releasing it to the public. Before you shoot your mouth off about how, “that’s dumb, anyone can just make more and make themselves rich!”, please do bother to check the forums and read the intelligent discussion that has almost certainly already covered your clever criticism.

Now, if you have any insightful or clarification questions, I’ll be happy to try to answer them here.

ADDENDUM #1 Many people have said something like, “There have been many other digital cash schemes, including those based on strong crypto, and they all failed. What makes bitcoin any different?”

The most important difference given the angle of this question is the lack of a central issuer. Bitcoin is an open source project. The code is out there. The network is peer-to-peer. Some of the peering mechanisms (IRC, hardcoded list of known good IPs) need some work, but there is NO CENTRAL AUTHORITY. There is no company to go under, no server farm to be raided, nobody to abscond with the gold from the vault. Bitcoins are “out there” in the network. What happened to Beenz, Flooz, and the others? They shut down, and poof went their currencies. The same would be true of WoW gold, Second Life Lindens, Liberty Dollars, and *gasp* Paypal US Dollars (read this, note especially “FDIC pass-through deposit insurance protects you only against the failure of the bank at which PayPal places your funds, and does NOT protect you against PayPal’s insolvency.”), just to start. Even if every bitcoin client on the planet shut down, until the last copy of the block chain is gone, bitcoins are there.

ADDENDUM #2 Please see also this newbie-friendly thread on the bitcoin forums discussing why bitcoin is not a scam, pyramid scheme, ponzi scheme, etc.

ADDENDUM #3 There was a comment about this being a ‘pump and pump’ vs a ‘pump and dump’ scheme from someone using a real economist’s name via Tor (nice one). Apparently this is an attempt to still make bitcoin sound like a get-rich-quick scheme, but to me ‘pump and pump’ sounds like ‘successfully bootstrap an economy’. There are basically two major scenarios for the future of bitcoin, in my mind. Either it succeeds, or it fails. (It could also limp along, but I’ll leave that out for now.) If it succeeds, anyone buying in will see an appreciation in the value of their bitcoins, long term, until the market eventually reaches some sort of equilibrium and level off. This is what I would like to see happen — everyone is a winner. If it fails, then most of the people with money in bitcoins will see the value of their holdings plummet, including me. This sucks but it still doesn’t make bitcoin a scam. The whole system is out in the open, invest only with your eyes open to the possibilities, positive and negative. Bitcoin investment and use at this stage is not for everyone. We’re just barely into the early adopter stage. Please, however, don’t call it a scam. Nobody is trying to defraud you.

ADDENDUM #5 Per a commenter below, I feel the need to address this because I’m hearing it over and over. People say, “Bitcoin makes early adopters wealthier, so even though it’s interesting and maybe useful, I’ll stay away, because I don’t want to help make them wealthier.” This is shortsighted. It’s like saying you’re not going to buy a stock that you think has a lot of potential because it would make earlier purchasers of the stock wealthier. It’s cutting off your nose to spite your face. Don’t think bitcoin is useful? Don’t use it. But I think it’s silly to avoid it because you think it’s a scam (as discussed here) or to spite earlier users.

Keynesianism has conquered the hearts and minds of politicians and ordinary people alike because it provides a theoretical justification for irresponsible behaviour. Medical science has established that one or two glasses of wine per day are good for your long-term health, but no doctor would recommend a recovering alcoholic to follow this prescription. Unfortunately, Keynesian economists do exactly this. They tell politicians, who are addicted to spending our money, that government expenditures are good. And they tell consumers, who are affected by severe spending problems, that consuming is good, while saving is bad. In medicine, such behaviour would get you expelled from the medical profession; in economics, it gives you a job in Washington.

A GoDaddy Vice President has been caught bidding against customers in their own domain name auctions.

I had been pretty happy with GoDaddy, despite their annoyingly busy web site, as my domain name registrar. I’ve even recommended them to other people. Now they go on the list of companies I refuse to do business with, including but not limited to Citgo, AT&T, and Wal-Mart. I’d like to refuse to do business with Comcast, but they have me over a barrel in terms of alternative choices, natural monopoly and all that.

This sort of personal boycott follows from my realization that money has supplanted voting in our capitalist society (and I have no quarrel with capitalism), and that both with politicians and with corporations, it’s important to vote with your dollars. In the case of Citgo, the two are combined.

Unfortunately, Anti-Intellectualism has been on the rise for about a decade, led by our Misunderestimated President.

Or, it was. All you have to do (assuming they already hold a political office) is check out Project Vote Smart.

Just punch in the name of the representative of interest, and you get a categorized list of their voting record, ratings according to various interest groups, campaign finance information, and more. Mysteriously-named bills are explained with summaries.

To get you started, here are some links directly to voting records and interest group ratings:

• John McCain: Voting Record – Interest Group Ratings
• Hillary Clinton: Voting Record Interest Group Ratings
• Barack Obama: Voting Record – Interest Group Ratings

The senate recently passed a new version of the Protect America Act that gives retroactive legal immunity to companies like AT&T for the illegal wiretapping of Americans that they have done in the past several years. The White House is pushing really hard for this to pass in the House now, because it grants immunity for their past illegal activity and that of their ‘friends’ at AT&T et al. However, if they were so desperate for continuous coverage, they would have accepted congress’ offer to extend the current PAA by three weeks, which they did not. Why? The extension did not provide immunity for the telecoms.

The EFF (to whom I donate regularly) has been pushing hard for over a year to get AT&T in the courts over this. This bill would totally halt their progress.

The Republicans in congress have walked out in protest, and are trying to say that the Democrats are compromising national security. This is nonsense. There are plenty of legal mechanisms for wiretapping with a warrant.

Please, take the time to call your representative’s office and let his or her staff know that you support their efforts to stop this bill. Or, if he or she is a Republican, a little chastisement might be in order. The list of representatives is here. It took me all of five minutes to find William Jefferson’s phone number and call his office.

As a guideline to help you, here’s a good basic framework of what to tell them, keeping it short and sweet:

• You support delays and even a stop in passing the new telecom act on the grounds that it includes immunity for illegal wiretapping.
• You don’t think that your representative will be endangering national security by not passing the bill.

Recent Gallup polls show that 43 percent of Americans reject the theory of evolution and instead believe that “God created human beings pretty much in their present form at one time within the last 10,000 years or so.” And at least four 2008 presidential candidates have said they do not believe the theory of evolution.

“There is a continuous threat to evolutionary biology and to science in general that has been posed by fundamentalists who reject entirely a Darwinian worldview because they feel it threatens their religious beliefs,” said Massimo Pigliucci, Ph.D., a professor of evolutionary biology at the State University of New York-Stony Brook.

43% — Keep in mind that while these people think God created humans in the last 10,000 years, we have evidence that dogs were domesticated by humans some 4000-7000 years before that.
