As with other recent articles, this one was originally published as an answer to a member of Quora, a Q&A site in which I am a cryptocurrency columnist. And just like the previous one in this Lifeboat series (also posted today), this is a Q&A exchange with a newbie—a bitcoin beginner.

The question is simply: “How can Bitcoin be divided into units smaller than one?” While the answer may seem obvious to someone versed in math, statistics or economics, I see this question a lot—or something very similar.

I can explain by asking a nearly identical question; one that the enquirer can probably answer easily. The goal is to provide the tools to answer the question—and in a manner that helps the reader recall and make use of the answer in the future. This is how I approached an answer…


This article was originally an answer to a member of Quora, a Q&A site in which I am a cryptocurrency columnist. The reader is a “Bitcoin beginner”. If you understand the nature and purpose of a blockchain, the political leanings of Satoshi or the economics of a capped cryptocurrency, then this reviews things that you already know. But sometimes, a recap can be fun. It helps ensure that we are all on the same page…

In a previous post, we have already addressed a fundamental question:

It has nothing to do with how many individuals can own bitcoin or its useful applications. It simply means that—if widely adopted as a payment instrument or as cash itself—the number of total units is capped at 21 million. But each unit can subdivided into very tiny pieces, and we can even give the tiny pieces a new name (like femto-btc or Satoshis). It is only the originally named unit (the BTC) that is capped.

But, this article addresses a more primitive question. (Actually, it is a naïve question, but this adjective has a negative connotation, which is not intended). I interpret the question to be: What prevents me from creating, earning or being awarded an amount that brings the total circulation above 21 million BTC?


The question is a bit like asking Why there are only two solutions to a quadratic equation? — Or (a metaphor): Why can’t you own a new Picasso painting?

In the case of Picasso, it’s because we know the ownership and location of the 1,885 paintings created during his lifetime. The Old Guitarist (shown at bottom) is at the Art Institute of Chicago. Unless there has been a serious error in record keeping, there cannot be any more paintings, because he is no longer around to produce new art.

You cannot create more bitcoin than the 21 million scheduled for release because that’s all the math yields. It is the capped quantity that Satoshi wanted in circulation—because he/she sought to create a deflationary token that could never be gamed by politicians or anyone else.

Consider the alternative. The Zimbabwe dollar had no cap. When the government needed more cash, they simply printed more. (This is exactly what the US does today). Eventually, they had 4 recalls and “official” devaluations. But, of course, the value of a Zimbabwe dollar (just like a US dollar, bitcoin or a Picasso painting) is not established by edict. It floats with supply and demand.

Eventually, 100 trillion Zimbabwe dollars was worth US 16¢. Then, it collapsed completely. You can still find a few 100 trillion dollar notes on Ebay. Ironically, they cost far more than 16¢, because western collectors are fascinated by them. Just as with a Picasso painting, all value boils down to supply and demand.

Of course, no citizen of means used the local currency even before it collapsed. They simply couldn’t trust their treasury. Today, Zimbabwe uses US dollars, rands (SA), British pound and euros.

What about the US dollar? Only the most arrogant citizens believe that we control such a vast consumer market (and that we are such a huge debtor) that the world must continue to value our paper. But is this realistic? Is it sustainable? Does U.S. debt ever have to be repaid with real sweat and real products sought by creditor nations? Of course it does. The alternatives are unthinkable: We would go the way of Zimbabwe, the Roman empire—or worse. Think of the Wiemar Republic between world wars.

The US dollar has no cap. A trillion or so new dollars are printed ever year, in a series of emergency measures that transient politicians call “raising the debt ceiling”, or an “emergency requisition”, or humanitarian, infrastructure, disaster relief, military necessity, debt repayment—or whatever. This leaves us 20 trillion in debt and with no path to recovery. Our own president openly asked why we can’t just print even more money to square up with our creditors.

With Bitcoin, we will never face that problem. Will adopting Bitcoin as legal tender interfere with a government’s ability to tax, spend or enforce tax collection? Not at all! But one day, it will decouple governments from control of their money supply. And that will be a marvelous thing—for both individuals, organizations and governments. It will force nations to balance their books—just like every household, business, NGO and municipality.

When this happens, governments can still raise money (from taxes) and they can even borrow. But just as with an individual or corporation, they will need to find:

  • Creditors (or shareholders) who truly believe in the ability to repay
  • This means they are creditors that believe in a nations institutions & ethics
  • And this leads to a conclusion: What better way to move our institutions and ethics in the right direction than through the accountability owned to our creditors.

Bitcoin is the embodiment of radical technology, but it is not a radical concept. It is the simple and functional embodiment of free-market economics. It addresses a market need that Aristotle fervently researched 2050 years ago, but failed to resolve. Gradual adoption is analogous to denationalization of telephony, airlines and package delivery services. Imagine the positive fallout when this occurs! Hopefully, we will around to witness a society in which governments are decoupled from monetary policy & control!

A new section: Bitcoin ATM business model
has been added. Jump to “2019 Update

The good news is that building a Bitcoin ATM is easy and less expensive than you might expect. But, offering or operating them engulfs the assembler in a regulatory minefield! It might just be worth sticking to selling bitcoin on PayPal (visit this website for more information on that). You might also wish to rethink your business model —especially user-demand. That’s the topic of our 2019 update at the bottom of this article.

A photo of various Bitcoin ATMs appears at the bottom of this article. My employer, Cryptocurrency Standards Association, shared start-up space at a New York incubator with the maker of a small, wall mounted ATM, like the models shown at top left.

According to futurist and author Daniel Jeffries, there are five key factors missing for crypto to fully succeed as a technology. Will Libra be the end of the traditional financial order as we know it? Does it pose an existential threat to people’s freedom?

Blockchain will make sure green pledges aren’t just green wash.


When a country or a company makes a promise to reduce carbon emissions, respect fishing quotas or cut toxic output, how can we be sure they’ll keep their word?

The truth is, it’s often extremely hard. But a new initiative — Global Ledger — led by a group of World Economic Forum Young Global Leaders (YGLs) aims to change that.

Using data from a nearly-infinite array of observation devices — drones, cameras, nano-satellites and soon-to-be-ubiquitous Internet of Things applications — reliable and unbiased information can be gathered and then stored using blockchain technology, which ensures data is verified and almost impossible to manipulate.

Just a few months ago, Augustín Carstens, the general manager for the Bank for International Settlements (BIS), the so-called central bank for central banks, said his organization saw no value in the potential of central-bank-issued digital currencies. Well, he’s apparently had a change of heart, and the entrance of Facebook and other “big techs” into financial services appears to be the reason.

The news: Carstens told the Financial Times that the BIS is supporting the “many” central banks currently developing or researching digital currencies. “And it might be that it is sooner than we think that there is a market and we need to be able to provide central bank digital currencies,” he said.

The context: Many other central bankers have dismissed cryptocurrencies like Bitcoin, which tend to be volatile and whose most popular use has been speculation. But Facebook’s proposed digital currency, Libra, will be backed by fiat money and designed to maintain a stable value.

Bitcoin reached the highest value the popular cryptocurrency has had in the last 16 months — $11,251.21 — on Monday.

And Facebook is likely to blame. Analysts suggest that the social media giant’s recent unveiling of its own cryptocurrency called Libra likely bolstered investors’ confidence in crypto across the board, according to Agence France-Presse. Though Bitcoin never really recovered from its massive crash in late 2017, the recent resurgence is a sign that the cryptocurrency isn’t quite fading away as some believed.
