Bitcoin Series 10: Why the $7M pizza does not matter (aka how to transact in bitcoin)

One of the central fallacies in the media about bitcoin is that volatility will hinder transactions.   This is usually expressed in one of two ways:

(1)    Bitcoin is going to soar to the moon so why should anyone spend their bitcoins? 

This is usually illustrated with the story of how Laszlo Hanyecz paid 10,000 for 2 pizzas in the first documented bitcoin transaction.    The theory being that if Laszlo had kept his 10,000 bitcoins they would be worth $7M today and makes those pizzas the priciest pizzas in world history.

While a great story, the conclusions drawn from it are usually dead-wrong.    After those pizzas were eaten, 10,000 bitcoins were still worth $30.    Laszlo could have trivially replenished his 10,000 bitcoins for $30, not $7M dollars.

This is a more general principle.   Whether or not you want to maintain a ‘long’ position in bitcoin (for investment purposes) is completely irrelevant to whether you want make a purchase in bitcoin (for convenience’s sake).

Imagine I have 10 bitcoins worth $7,200 as of this afternoon because I have decided that is how much investment exposure I want to bitcoin.   And I want to order 6 pizzas for $72 because football is on, my buddies are drinking all my beer and if we don’t get some food in us bad things are likely to happen.

I can either: (a) pay $72 with my credit card in US dollars and still have 10 bitcoins and 72 fewer dollars or (b) buy the pizzas with 0.01 bitcoins and then press one more button and replenish those 0.01 bitcoins with $72 from my bank account.    At which point I would have 10 bitcoins and 72 fewer dollars.

If I instead buy the pizza with bitcoins and do not replace them, then I have made two decisions: (a) to spend $72 for pizza and (b) to reduce my long exposure to bitcoin by 1% (0.01 bitcoins).   But decision (b) has nothing to do with decision (a).

(2)    The volatility of bitcoin creates uncertainty for merchants.    This is just factually inaccurate.   Both major US payment processors (Coinbase and Bitpay) offer vendors the option to convert  bitcoins received back to US dollars as they receive them and take on no bitcoin ‘currency’ risk.  When I read articles in serious publications worrying about this, then I know who hasn’t done their basic homework.

I tested this whole concept in practice a couple of weeks ago when I paid our IT consultant’s latest invoice with 4 bitcoins or so.   I paid him 4 bitcoins, bought 4 more bitcoins 3 seconds later and he made a decision later about when he wanted dollars for his bitcoins.    It was trivially easy and no different than any business that transacts cross-borders deciding to accept money in a second currency.  The only difference I could note is that it took a few seconds to deal with instead of several days.

Bitcoin Series 9: Five reasons that bitcoin is currently volatile and why it does not matter

One of the major ‘criticisms’ of bitcoin is its volatility in relation to traditional currencies.   I do not worry about this because it is an inevitable outcome of a brand-new asset class.   In the event that bitcoin works and becomes adopted, volatility will diminish.  If bitcoin is not adopted, who cares if it is volatile?

The main drivers of bitcoin volatility are below.   In any positive outcome for bitcoin, they will diminish over time.

(1)    Regulatory Uncertainty.   The regulatory landscape has only started clarifying in the last couple of months.   Over the next two years, every major economy will have clear guidance (positive or negative) relating to bitcoin regulation and we will no longer have positive (US) or negative (China) surprises.

(2)    Money Supply:  The total value of the bitcoin money supply is less than $10B.    M1 for traditional currencies worldwide is in the range of $30T.   So trivial movements in traditional currency markets cause tsunami-like movements in bitcoin markets.

If bitcoin gains further adoption, money supply will almost by definition increase.    To believe otherwise would suggest that, as adoption increases and volatility decreases, the price will go down, aka fewer people will want to hold bitcoins than do today.

(3)    Liquidity:  Total bitcoin trading has exploded.  It still represents less than $100M of trading per day.   Traditional currency trading is measured in the trillions of dollars daily.   As with money supply (#2), bitcoin trading volume is still too small to absorb traditional currency market shifts smoothly.   Similarly, this will alleviate itself naturally as bitcoin becomes more adopted and trading volume increases.

(4)    Market access:  There are only three major exchanges (that trade traditional currency for bitcoin) in the world right now, each with some issues:

a. Mt. Gox in Japan that has not solved its issues in redeeming US dollars

b.      BTC China that has had most mechanisms for depositing yuan blocked by the Chinese government

c.       Bitstamp, a small company in Slovenia (that 2.5 years ago ran a computer shop) that handles most of the exchange volume for the United States and the EU

Anyone with experience with financial markets will recognize the absurdity of the current situation.   Japan and China have crippled exchanges.   In the US and EU if anyone wants to buy more than a few thousands of dollars worth of bitcoin in a day, they have to wire US dollars to a small unknown firm in Slovenia.    This is in no way a criticism of Bitstamp; they have done excellent work.   But pension fund manager, hedge fund or endowment is going to wire $20M of pension money to them given the perceived counterparty risk.

This is a really important point.   Once people feel more comfortable moving institutional money in and out of bitcoin for trading purposes, it will create liquidity, start to generate a market-making and stabilize the swings.

This will also allow the development of advanced financial / hedging instruments that allowing people to take different positions vis-a-vis the currency.

(5)    Limited transactions:   Adoption of bitcoin as a payment mechanism is still in its infancy.   We are still at the stage where it is world news when a firm accepts bitcoins.   As this changes and more payments are actually conducted in bitcoin, there will be a steady stream of non-speculative buying and selling of bitcoin that will provide day to day stability and liquidity.

Summary:  So long as adoption of bitcoin continues, the factors that create bitcoin volatility will diminish in their impact.   If for some unknown reason, bitcoin is a bust, then volatility will not go away.  But, in that case, who cares?

I will concede that it is possible that bitcoin, with the lack of a central bank, will always be a bit more volatile than traditional currencies, but it will stabilize at a far more stable range than it has today.

As a side note, it amuses me to see the financial services industry so concerned about bitcoin volatility.   This is an industry that has brought us options, derivatives, junk bonds, CDOs, CDOs squared and so on and has never met a way to enhance, hide or restructure volatility that it did not like.  Similarly, I can’t imagine how volatile the tech industry would look if we valued VC portfolios by trading every early stage company 24/7/365 on a variety of exchanges worldwide, keeping in mind the majority of them will go to zero.   Yet nobody is suggesting that we can’t societally handle this volatility and even invest the pensions of working class people in it.

Bitcoin Series 8: Who is investing in bitcoin today?

First think about what value bitcoin provides as a store of value.  Given that, it makes sense who are the early investors in bitcoin.

While this is an over-simplification, there are three classes of investors today in bitcoin.

(a)    Early tech adopters for obvious reasons:  They see a platform for the future even if they don’t always understand all the financial implications.

(b)   Gold bugs and other anti-Fed / anti-inflation types:  They like the limited supply of bitcoin and view this as a new ‘gold’.  

(c)    Family offices and individuals within hedge funds:  These are the first semi-institutional investors in bitcoin.   Family offices do not have strict external guidelines for their investments and don’t have to worry as much about documentation and compliance issues.    Individuals in hedge funds that cannot yet invest institutionally have being doing so personally. 

What is the thought process here?   If you put 1-3% of assets in bitcoin, the volatility of bitcoin has limited impact on your overall portfolio (that is probably moving 1-2% daily anyway).    In terms of ultimate outcomes, the downside case is that it goes to close to $0.  The upside case is probably 10x to 20x from the current prices.   The probability of each case is an unknown.   A lot of people will take that bet with 1% of their assets.   If it does not work, a 1% loss does not change anyone’s life in any way.   If it does go up 10x, then you get to feel very smart, a visionary and so on.

The pure institutional investors are still, for the most part, on the sidelines.   This is understandable.   Bitcoin just entered the general business consciousness in October 2013, less than 3 months ago.   It will take time for both financial institutions,their support industries (legal, accounting) and regulators to understand bitcoin and figure out the liquidity, regulatory and compliance issues.  

-          How do you prove to your auditors that your fund does in fact control $10M worth of bitcoins?   It is a solveable question, but the infrastructure is not yet in place

-          Can you buy and sell $5M of bitcoins (a trivial amount of money) without moving the market.  Today the answer is ‘No.’

-          Are you willing to take the counterparty risk of the current exchanges?

I don't think the institutional investors will stay on the sidelines forever.   The financial services industry is relentless attracted to fee-generating opportunities and will find their way to bitcoin too.
