In the last week or so there has been a deluge of media attention, Twitter comments, and blog posts about Bitcoin. Unfortunately many people are jumping to the conclusion that bitcoin is a scam, ponzi scheme, etc.
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.

Nice one! Tnx a lot, just fwdd to all friends, could be the only decently short explanation for those who, as yo stated, don’t bother with real explanation of things.
The most important part of this message seems to be “I own a bunch of bitcoins, I mine for bitcoins.” I don’t know if it’s “pump and pump” or “pump and dump,” but whatever this is, it’s a get-rich-quick scheme for you. Sorry, but no thanks.
Oh, erasing comments now? How honest of you. What a scam!
Actually I screen new commenters to avoid spam, how rude of you! To others, please be patient if your comment doesn’t post right away, I don’t moderate 24/7. Once I approve one of your comments you won’t have to wait the next time. I reserve the right to delete abusive comments.
I can see you missed the point, did you even read beyond that statement?
It’s the gold rush of the internet. Call it a scheme if you like, but with the block chain over 2 years old, I would hardly call it “quick”.
You own bitcoins? Sounds great, maybe I will buy some with Beenz, lol.
Thanks for the tips so far!
Very nice article! Thanks.
I actually do not understand people who have the energy to make a negative (uninformed) comment. With that tiny bit of effort to type a message, they could go from (tl;dr) to: WOW!
Oh well… the world was ‘flat’ for quite some time 😉
Great article, thank you so much for writing it.
Especially the mining process can be really hard to grasp.
I’m actually really curious, what have you bought with your bitcoins? What sort of things/services are available to buy with bitcoins. Is there anything you can only buy with bitcoins?
Dani: With bitcoins I have bought gold, some Linux stickers, and recently a nerd merit badge “I bought this bitcoin badge with bitcoins.” That last one answers the other part of your question.
I’ve spent a lot of bitcoins rewarding people’s useful posts online, on the forums, software projects, donations to the EFF, etc.
Bitcoin is going to change everything. Here are some ways Bitcoin will change everything!.
The funny thing about cc5alive’s comment is I’m not even sure whether the linked post is satire.
“Why Bitcoin is smart and not a scam”, written by someone who is accepting bitcoin donations. How very surprising.
It is smart for the inventors of the scheme, who are guaranteed wealth because they ‘mined’ the first easy ‘bitcoin’ and due to the increasing difficulty of producing more coins. They only have to hold back some of those initial coins and then do absolutely everything they can to get other people to join in, as we are seeing now with posts like this one, marketing a gold rush that will never make us as much money as it makes them.
See also the discussions like this here:
An active blog-based marketing push is taking place by people who know their initial coins will increase in value if the system becomes popular, and as such the bitcoin forum is full of individuals self-justifying their marketing a system as egalitarian, unregulated and fair when in fact their aim is to make themselves wealthier than others by doing so.
Why should I use a brand new currency scheme that makes its early adopters constantly wealthier regardless of their subsequent involvement in any sort of trading?
It is not a scam based on the examples of scams in existing currencies, but it does look a _lot_ like pyramid selling to me. I eagerly await the law catching up with this shit.
Also: ‘mining’, and ‘bitcoin’ as its own plural: I will never get used to this.
Michael: I mean that it is smart because of the incentives that are built into the system. Anyway, take it or leave it, that’s for you to decide. I just got sick of people saying it was a “p2p ponzi scheme” on twitter, which it is not.
I still think (a) bitcoin is a revolutionary technology with the potential to cut out a lot of expensive middlemen in the financial sector and (b) there is still quite a lot of upside left in it for new users. If you think a and b are true, but don’t want to use it to spite earlier users, well, that’s your choice.
Also, what’s wrong with taking bitcoin donations? That’s one of the things they are best for. I’ve given quite a few bitcoin donations myself. Ever tried it?
I saw that merit badge earlier on boing boing. Glad to hear you got yourself one.
Dani: Yes, I think you actually brought that to my attention. Aside from the many things you’ll see listed on the Bitcoin site, if you look in the forums there are often other goods/services for sale. I forgot, I hired a couple of virtual assistants from the forums once and they did a fantastic job. Paid in BTC of course.
Jason should look at how government currency is created then compare it to bitcoin. I would say that the current system is created to make bankers rich and keep it that way, thanks but no thanks.
Question? Can the network be attacked by enough people downloading a version of the software that changes the rules? For example governments want more coins have a campagn to get more coins in the hands of the people and tell people to upgrade.
This is thinking far out so we know how the system could get attacked.
The network is controlled by the majority of hashing power. So, yes if enough users ran modified clients and mined with fast enough hardware, the rules could be changed. This is a good incentive to current users to keep the network power high.
To clarify: if they change the rules such that their blocks become unacceptable by current rules, the block chain will just fork. they can’t force users of the ‘original-rules’ client to accept the new blocks.
people would just then be able to choose which branch of the chain they want to be on.
in other words, they cannot change the rules for people who don’t want the rules to be changed.
I agree that this is the future, unfolding right now. My only question is, will the governments allow this to prosper?
Are we not looking at a scenario where some countries ban this outright (they even banned youtube, so.. )
StatSpotting: It may be banned. I think it will be tricky in a legal sense to ban Bitcoin but not, say Facebook credits, but only time will tell.

Early adopters wealther, no problem with. The problem is if bitcoins are successful, they make earlier adopters kings. Consider only about 2% of the bitcoins are being traded, the rest are hoarded. That means early adopters hold 98% of the bitcoin wealth. If they are smart they will continue to hoard. Which means if every currency in the world was eventually replaced with bitcoins, each bitcoin would be worth $150 million dollars. (This is assuming 100% of currency converted into the 2% of bitcoins available on the market.) Considering some entities literally will have millions of bitcoins they have been hoarding, that means there would be individuals with more wealth than whole countries.
I’m sorry, but I don’t think this is the type of redistribution of wealth I am willing to support.

Bill: If you don’t want to use something that you find good and useful because someone else will benefit, it seems to me that’s cutting off your nose to spite your face. In fact, by that logic, why engage in trade for anything?
Nonetheless, that’s your choice, you’re welcome to make it, and bitcoin will succeed or fail regardless of the few that share your sentiments.
Can you compare Bitcoin to a barter system? Bitcoin sounds very interesting because from what I gather, it is used as a medium for exchange, vice being used to bankrupt a nation and its people as are FRN. In a pure medium such as this, the value of BTC will not ever approach zero, unless people forget about it. And one of the things that will make people forget it will be making it too damn complicated to actually use in a marketplace.
In order for you get something out of bitcoin, you have to have some way to put in something. The ‘something’ would be valuable, like gold, for example. Notice I do not suggest USD because ever since 1913, the value of one USD has declined nearly 100% because it’s not backed by anything. My question is, how to put value in to receive value out (buy and sell)?
thanks for the detailed explanation. I’m very much new to the concept and nuances of bitcoin, but feel encouraged to keep digging…or should I say, keep mining.
I love bitcoins, just wanted to say thanks for your article.

What prevents someone with coming out with an alternative? I mean i could use the same software as Bitcoin and relaunch a new currency – ‘NewBitcoin’..what then is the legitimacy of bitcoin as a store of value?
By limiting the supply of Bitcoins the prices have shot through the roof, as people hoard it..does that destroy an economy as it takes out purchasing power that would otherwise have lead to people buying goods and circulating money?
Regarding alt-coins, they exist and they are gaining some traction. However, there is a strong network effect with Bitcoin. Some of the alt-coins have properties that are more or less valuable to different people. Only time will tell.
Regarding hoarding, everyone has different amounts at which they are uncomfortable holding something as risky as bitcoins. This will lead people to spend/cash-out at different levels and help maintain liquidity. As more people use Bitcoin and more are in circulation, I think most people expect that the volatility will decrease.
