Cryptocurrency Markets- concentrated and top heavy

go Distrust in  fiat currency, controlled by a state, was one of the principal motivations in designing of  the Bitcoin protocol. It was designed  to be a decentralized system of creation of new money by a transparent computational algorithm.  Any person participating in the currency’s ecosystem can run this algorithm on a computer and generate new money. It is supposed to be a currency created by the people for the people and therefore a currency of the people. It is a currency of future when true democracy will prevail. here  here  here  here  here

But what is the reality? Who owns the bulk of these virtual currencies? To get an answer to this question, I looked into data about the distribution of these currencies amongst the participants in this technology game. The result of this exercise is truly revealing.

Data: We have collected data from the website https://bitinfocharts.com/top-100-richest-bitcoin-addresses.html which gives “Rich List” of some selected 9 currencies. We collected data as on 11th April, 2018. The market cap of these 9 currencies was 58.8 per cent of total market capitalization in terms of US dollar on that date.  On the data date, the total market capitalization of virtual currencies (excluding tokens) was 261 billion US dollar. So one can say collected data is adequately representative of the virtual currency ecosystem. The website has grouped data by value of coins  held against each address. An address having , say 0.001 bitcoin (BTC), would be grouped in the bucket “0 to 1 BTC” bucket.  For some cryptocurrencies , the number of coins held in an address may be very large as their market value is much smaller as compared to that of Bitcoin.  So the number of class intervals for coins held would be higher than a highly valued cryptocurrency like Bitcoin. To keep the results compact we have collapsed crypto wise class intervals into a common 3 classes. The following table gives a summary of distribution of value in US dollar and number of addresses across these class intervals.

Table 1: The distribution of addresses in terms of value of coin held and number of addresses for various class intervals of value of coins for each address.

Peercoin 0.0 0.0% 1.3% 98.7% 56.4% 32.0% 11.6% 934

 

It is obvious from the above table that only few addresses, each having more than 100 coins per address account for the bulk of total market capitalization of each currency. Bitcoin which the highest market capitalization of all circulating coins is also concentrated in a small number of addresses. The table 2 below clearly indicates how a few big market players have completely taken over each currency market.

The US tax authorities as well as Commodity Future Trading Commission have designated as “commodity” and not currency. From that perspective, this commodity market is highly monopolistic and susceptible to market manipulation by few large traders.  It is high time that anti-trust authorities in the developed economies wake up to this reality and take appropriate actions in the interest of average participant in these markets.

Central Bank Digital Currency -a Blueprint

eRupiah: RBI’s Virtual Cash

Key words: Central Bank Digital Currency, public key-private key cryptography, Digital currency wallet, Corruption,

go to site Introduction: No currency has ever been used in the human history which did not have the stamp of an authority. Bitcoin is a medium of payment but it is not money for the same reason. Nonetheless, the technology underlying Bitcoin is a significant one with great potential. A central bank, issuer of paper currency, can use some selected components of Bitcoin technology to replace paper currency with virtual currency, retaining all the important features of paper currency. The most important of them is that a central bank note is a freely negotiable bearer bond and a legal tender in the hand of its holder. It does not require any third party verification. Counterfeiting a central bank note is not impossible but difficult and costly. The central bank neither authenticates any transaction made with that particular note nor does it keep any record of that transaction. The note remains as a liability on the book of the central bank till it comes back to it, either for reissue or its destruction. The physical nature of the note ensures that no double spending is possible with the same note by its current holder. In case of digital cash, the main issue that a central bank has to resolve is the issue of double spending without depending on third party verification of the same. What follows hereunder is an outline of a system that any central bank can implement to issue its own currency retaining most, if not all, of the desired properties of a paper currency.

I am presenting below a system based on digital currency on a mobile phone. There is no compelling reason to believe that the same system cannot be implemented on a specially designed smart card with embedded chip. The system outlined below is described within the currency management framework of the Reserve bank of India (RBI). With little tweaking the same can be customized by any central bank.

http://celebritysex.cz/?triores=singles-dating-events-singapore&654=dc RBI Currency Management Framework:

RBI carries out its currency management function through its 19 Issue Offices located across the country. There is a network of 4281 currency chests and 4044 small coin depots in selected commercial bank branches. These chests store currency notes and rupee coins on behalf of RBI.  The note distribution mechanism is summarized in the following diagram.

For issuance of digital currency, each currency chest would function as a data center for hosting the ledger book of notes issued from it.   Similarly each issue office of RBI would have a copy of the entire ledger book of notes. A folio would be opened in the note ledger book when the first time a specific note is issued.  Each data center will have complete inventory of wallets issued by RBI.

Every bank branch would have a digital cash dispenser. Any wallet holder would be able to replenish her wallet with digital currency by pairing it with the dispenser via Bluetooth or NFC communication channel.  Similarly every ATM would have similar facility. At the time of cash dispensation from bank branch or ATM would require Aadhaar based biometric verification of wallet.  For cash transfer between wallets of two individuals this verification is not a necessary requirement.

http://www.hamburg-zeigt-kunst.de/?biudet=bin%C3%A4re-optionen-bollinger-bands-strategie&d0f=36 The protocol for issue of eRupiah

  1. RBI would maintain ledgers of each currency note in a distributed database.
  2. Currently RBI issues notes through its Issue offices. The distributed database will be created according to issue departments of RBI. Each Issue office of RBI will be able to issue new digital currency and destroy old digital currency. Destruction of old digital currency would help RBI to keep the number of entries in the ledger folio of a particular note within a limit. Every Issue offices would maintain record of all notes issued by it as well as copies of corresponding records of 3 neighboring Issue offices.
  3. Each currency chest will have a database of notes received by it from RBI’s Issue department.
  4. Each currency chest will also have replicated database of its three nearest neighbor
  5. The system will issue new digital currency when an account holder wants to withdraw cash from its account with RBI.
  6. The account holder would specify how much of its cash withdrawal would be in digital form. This facility would be provided for an interim period when both forms of currency would be in circulation.
  7. To incentivize issue of digital cash, RBI may reward with a fixed amount that could be related to the cost of producing physical cash.
  8. RBI is banker to the Central and State Governments. It also functions as banker to the banks and thus enables settling of inter-bank obligations. These account holders of RBI would get digital cash in their Jumbo Wallet which would be a server in the account holder’s custody. It would be like a till holding cash. An authorized person can withdraw e-Rupiah from the till as and when required.
  9. The RBI’s Note ledger would comprise ledger folios of each currency notes issued.
  10. Each record in the Note ledger would comprise the following attributes: (1) a sequential no, (2) unique identity / sr no of a note, (3) hashed value of the note serial no, (4) identity of the issue department, (5) denomination, , (6) time stamp of transaction, (7) hashed value of identity of paying wallet (first time payer would be RBI), (8) hashed value of identity of receiver wallet, (9) active flag,   (10) hashed value of first 9  attributes , (11) hash value of the first 9 attributes of earlier transaction record of the same note. The identity of a wallet is described below.
  11. RBI will also maintain database of each wallet downloaded from its website.
  12. The wallet database will have a header record with the following attributes (1) IMEI no of each phone, (2) Aadhaar No of the phone owner, (3) timestamp of successful downloading of the wallet, (4) the GPS location of the phone at the time of downloading of the wallet, (5) a unique private key generated for each wallet and (6) the corresponding unique public key generated for each wallet. This data would also be hashed and encrypted with RBI’s private key and will be part of the header record. RBI’s public key would also form a part of the header record. The private and public key of each wallet would be generated by RBI at the runtime. The hashed value of attributes 1 to 6 would be the identity of each wallet.
  13. Each wallet will have its own database of transactions. Each record in the transaction database will represent a note that has been loaded into the wallet. Each record will have the following attributes: (1) unique identity of the note, (2) note denomination, (3) digitally signed (with the private key of the paying wallet) hashed value of the concatenated string of serial no and denomination, (4) digitally signed ( with the private key of the paying wallet) hash value of concatenated string of attributes 1 and 2 of the header record with private key of payer wallet, (7) public key of the paying wallet, (8) timestamp of last transaction( i.e. timestamp of receipt of the note , (9) timestamp of the payment transaction, (10) payment status (paid or unpaid), (10) hashed value of the earlier transaction of the note(attributes 1,2,3,4,5).
  14. A transaction between two wallets would involve “note data” transfer from the paying wallet to receiving wallet. Every note that gets transferred from the payer’s wallet to the recipient’s wallet would essentially mean transfer of the entire record from the former to the latter. In the process of data transfer two insert / update activities take place in the receiver’s and payer’s wallet respectively. The receiver’s wallet inserts a new note record while the payer’s wallet updates the concerned note’s existing record.
  15. Once the receiving wallet gets a new e_Rupiah note, it checks the authenticity of the note by calculating hash value of the concatenated string of attribute 1 and 2 of step at 13. In the payer’s wallet the status flag would get changed to “paid” while in the receiver’s wallet it would continue to have the status flag as “unpaid”.
  16. Any wallet would have a limit in terms of number of records / notes. When the database has reached its limit then the wallet would have to be uploaded to RBI and a new wallet has to be downloaded.
  17. At any point of time a single wallet would be subject to 2 limits- holding limit of no of transactional records and total value of a single transaction. For a high value transaction two factor authentications would be required. (say above one lac). Both paying wallet as well as receiving wallet has to simultaneously establish connection with RBI and get their credential verified.
  18. As and when no of records in a wallet’s transactional database reaches its limit, the database has to be downloaded in an ATM or at a bank branch. The wallet would be purged of the all transaction records with status as “paid”. The wallet holder then can download more E_Rupiah from an ATM or from a bank brunch. RBI will update its ledger book of individual notes thus uploaded from each wallet.
  19. Any fraudulent transactions identified in the process of uploading would get notified and thorough automated forensic audit perpetrator of fraud would get identified.

Trading or Investing in Bitcoin is Injurious to your Financial Health.

One of the fundamental lessons of all financial scams is that there always exists enough number of gullible people to be conned by merchants of dream. For example, the people of 17th century Amsterdam started believing that prices of a bunch of tulip bulbs could rise to a level higher than the value of a furnished luxury house. It also happened during the dotcom bubble of late 1990s. Presently such a bubble is unfolding before our own eyes and the sad part of it is that some financial sector regulators are actively encouraging formation of this bubble in the name of financial innovation. It would be apposite here to recall the scathing criticism that the Financial Crisis Inquiry Commission of US Congress made of the regulatory failure leading to the sub-prime financial crisis:  We conclude widespread failures in financial regulation and supervision proved devastating to the stability of the nation’s financial markets.

U.S. financial firms CME Group and CBOE are going to launch Bitcoin futures on December 18, followed by launch of binary options on Bitcoin by Cantor Fitzgerald. The US regulator for futures market, Commodity Futures Trading Commission (CFTC), has allowed introduction of these new products by these exchange platforms on the basis of self-certification submitted by them. The Commodity Exchange Act of USA allows such exchanges called Designated Contract Markets (DCM) to introduce new contracts by submitting a written self-certification to the CFTC that the contract complies with the Commodity Exchange Act (CEA) and CFTC regulations. It is the responsibility of DCMs to determine that the offering complies with the CEA and Commission regulations.

The CFTC in its press release of 1st December has referred to the IRS characterization of Bitcoin as a virtual “currency”. More than that, IRS has referred it as “convertible virtual currency”. I have already explained in my earlier blog why Bitcoin cannot be called a currency. In 2015, CFTC declared Bitcoin as a “commodity” by referring to the CEA act that includes “all services, rights, and interests in which contracts for future delivery are presently or in the future dealt in.” in the definitional boundary  of commodity. The press release clarifies that “Bitcoin and other virtual currencies are encompassed in the definition and properly defined as commodities”.  Under CEA commodities are classified into three categories-

(1) source site Agricultural commodities

(2) hong kong gay speed dating Excluded commodities which include, inter alia, an interest rate, exchange rate, currency, security, security index, credit risk or measure, debt or equity instrument, index or measure of inflation, or other macroeconomic index or measures

(3) http://airshow-magazin.de/images/twentheshow16.jpg Exempt Commodity which means a commodity that is not an excluded commodity or an agricultural commodity.

Prof.  Shadab of New York Law School has argued in his written statement submitted to the CFTC that Bitcoin should be classified as “exempt commodities and not as excluded (currency) commodities “.

Each Bitcoin future contract on CME would be composed of 5 Bitcoins. The tick size (the minimum fluctuation) has been fixed at $5 per bitcoin, amounting to $25 per contract. Per person open position limit has been set at 1000 contracts. The daily price fluctuation of a Bitcoin future is limited to a 20% band above or below the prior settlement price.  The settlement price will be Bitcoin Reference Rate (BRR). BRR is calculated by UK based crypto currency trading platform -Crypto Facilities Ltd, in partnership with CME.  BRR is calculated by taking traded price and volume data from a few selected exchanges involved in spot Bitcoin trading.   Price and volume data are obtained for 12 periods of 5 minutes each   in the last hour of trading. For each time interval, a volume weighted median price is calculated. The overall price is average of these 12 prices.

So, purely from methodological perspective, construction of reference price cannot be faulted. Since BRR is based on observed prices of Bitcoins traded on mostly unregulated exchanges, these prices are always subject to manipulation.  The extent of volatility that can happen on these exchanges can be understood from the movement of bitcoin price on December 7. On this day, the price of 1 Bitcoin fluctuated from a high of USD 19,000 to a low of USD 4,000.  If the price volatility is considered in conjunction with volume volatility (see the graphs below), Bitcoin may turn out to be Twenty First century’s first virtual Tulip.

Given this “insane volatility” ( as described by the chairman of BBCBS committee) of spot prices of a traded asset, the CFTC’s move  in allowing derivative products  on such an asset can be highly counterproductive. Apparently the CFTC believes that by bringing Bitcoin on a regulated platform it would be able to contain the speculative excess.  The high margin requirement is expected to dissuade small investors to take positions in the Futures market, leaving the field open for play by institutional investors. More than 100 hedge funds have been created in the last one year to trade in digital currency only. It is reported that there is $10B of institutional money waiting on the sidelines to invest in digital currency today. To meet the requirements of these institutional investors, Coinbase, the US based Bitcoin exchange, has launched a new company to store securely their digital assets (see here). The company has claimed that it is already holding $9 billion of digital currency on behalf of its customers.

It should be a matter of regulatory concern about the source of Bitcoin’s price volatility. Apart from alleged price manipulation the most plausible explanation would be the intrinsic unbridgeable gap between demand and supply of Bitcoin. New supply of Bitcoin is largely a result of mining activities and the maximum supply of Bitcoin is a known figure. Against the back drop of a largely inelastic supply curve, the demand curve is driven by enthusiasts of cryptocurrency- a fast growing tribe. The fundamental inelasticity of the supply curve is getting reflected in higher and higher cost of Bitcoin based transactions.   The following two graphs show how running Bitcoin network becoming costlier and costlier.

 

 

 

 

 

 

Given its inherent supply constraint, there is no possibility of Bitcoin becoming a global currency in its current form. Since Bitcoin is a highly sophisticated technological product, it attraction to young people is immense, like marijuana once was. But it should be the job of central banks to proclaim from the rooftop with as much force as it can command that: http://ligaspanyol.net/?mikroskop=site-de-rencontre-des-femmes-togolaises&034=16 http://hallsglobal.com/?mikronezia=rencontre-plus-de-cinquante-ans&601=f1 Trading and or Investing in Bitcoin is injurious to your financial health.

Central Bank Cryptocurrency Currency

Central Bank CryptoCurrency (CBCC):

Digital currency is currently in news.  Russia and China is reported to be on the verge of issuing official cryptocurrency.  CME, the world’s largest exchange, is planning to introduce future on Bitcoin by the end of this year.Here Here  In my last post I have explained why Bitcoin can be considered at best a currency of a community- a virtual country, so to say-  of Bitcoin users. So a future on a foreign exchange of an unknown country without any verifiable foreign  trade activities  is definitely problematic.  Be that as it may; the possibility of introducing digital currency by central banks is now a hot topic. The head of the Secretariat of the Committee on Payments and Market Infrastructure of BIS along with a colleague has recently published a paper on the Central Bank Cryptocurrencies.  In this paper the authors have identified four key properties of Money- issuer (central bank or other); form (electronic or physical); accessibility (universal or limited); and transfer mechanism (centralised or decentralised). It is interesting to see that the authors have failed to identify the most important property of money- unit of account. A medium of payment is not a currency unless it is also a unit of account. That is why  a credit card, a bank debit card or a prepaid cash card  is not money, despite each being a digital medium of payment.   In fact, in terms of volumes as well values, the medium of payments even in a developing country like India is largely electronic. The following table shows that money in India exists mostly in the digital form, as most of the bank money is. Even after exclusion of  time deposit from the ambit of  payment system, the digital money ( bank money)  dominates the physical money or cash.

Composition of Broad Money (M3) in India

So issuance of central bank currency would only digitalize the cash component of money as other medium of payments are already in digital form. So  CBCC  should be considered only as a replacement of physical cash issued by a central bank.  The champions of cryptocurrency, however,  would like it to be the sole medium of payments, at least of the online variant. It is difficult to understand why anybody would like to replace a part of the system that is working fine with another only because of its compatibility with a particular ideology about issuance of money.  In fact, instead of reducing the cost, a decentralized transfer mechanism like bitcoin would increase the social cost of running a payment system.  Leaving aside these ideological issues about money for now, let us consider the possibilities of issuing cryptocurrency by a central bank. I intend to outline a protocol that can be adopted in the specific case of India. In this post I enumerate the essential features that a Central Bank Cryptocurrency Currency(CBCC) should possess with specific reference to India.

The Reserve Bank of India (RBI) spent on average 35 billion of rupees in printing notes in last 3 years, ignoring the spike of 2016-17 due to demonetization. This amounts to more than 500 million dollars- not a small sum.  The commercial banks also have to incur huge cost  over and above the printing cost incurred by RBI to manage the last mile of the currency supply chain.  If we can replace printing of notes by creating digital strings of binary numbers in computers, the total cost could be easily reduced significantly.  It is not necessary to eliminate physical cash completely. Digital and physical cash could coexist for a long time to come. When every citizen is connected to the digital space we can think of complete elimination of physical form of cash.

Let us first understand how the paper currency system works in India. Before that, we need to consider the enormity of logistics involved in cash management system in a country like India. As on end March 2016, 90 billion pieces of notes and 89 billion pieces of coins were in circulation in India. The number of currency chests and coin depot/sub-depot were 4211 and 4008 respectively at the end of 2012. There were around 222 thousand ATMs in India. The details of the currency supply chain is given below.

  1. Note printing presses print notes as per indents placed by Currency Management department of RBI.One characteristic of the paper note is worth noting here; every note has a distinct identity.
  2. RBI receives the currencies in their vaults
  3. RBI remits the currencies so received to various currency chests maintained at bank branches.
  4. The commercial banks run the currency chests as an agent of RBI, while the treasure in it is the property of RBI. Any withdrawal or deposit into the currency chest is recorded as debit or credit respectively in the bank’s account maintained with RBI.
  5. Transport of currencies from currency chests to other bank branches  is the responsibility of banks.
  6. General public can obtain cash from banks either over the counter of bank branches or from ATMs. Government departments having accounts with RBI  withdraw cash from RBI counters to meet their cash needs, and thereby inject cash into the economy.
  7. When general public or government departments deposit cash into their bank accounts, the banks or RBI examine the circulation worthiness of deposited notes. The soiled notes are then withdrawn from circulation and briquetted by RBI.

We are interested in designing a supply chain that delivers digital currency to general public, maintaining the basic functionality and integrity of the existing supply chain.  We need not differentiate between notes and coins in the digital environment. .

The main characteristics of the proposed CBCC would be as follows:

  1. Each note would have specific denomination- large denomination of 5000 and 10000 can also be introduced.
  2. If Alice wants to pay 102 rupees to Bob and Alice has only one 100 rupees and one ten rupees in her wallet, the system would function exactly the way cash based transaction would function. Alice would pay one 100 and one ten rupees to bob. Bob would immediately pay back to eight rupees to Alice in denominations available to Bob.
  3. Like Bitcoin there would be wallets as app in mobile or users can use hardware based wallet also. There is no question of having any exchange as custodian of wallet in dematerialized form.
  4. A person without a bank account can download a wallet and can receive digital currency in this wallet.
  5. There would be no connection with a wallet with wallet holder’s bank account. However, a wallet holder would be able to download cash from her bank account as currently she withdraws cash from her bank account. The only difference would be that the bank / ATM would give her digital cash and not physical cash
  6. There would be no special KYC verification for downloading digital wallet apart from providing a unique identification number.
  7. In case of loss of a wallet, the process would be the same as it happens if one losses one’s physical wallet containing physical cash. A First Information Report (FIR) has to be registered with a police station and the system would ensure that missing digital notes are blocked to the extent the digital money in the lost wallet has not been spent till that time. After completion of investigation the cash can be restored to the original owner.
  8. The central bank may prescribe a limit to the value of digital currency a wallet can hold. For example, it may be stipulated that the wallet is designed to hold a maximum amount of 100 K rupees. A wallet holder would not be able to load cash to her wallet from a bank or from another payer more than amount.
  9. It may be possible to take insurance for loss of a wallet with a sum insured to the extent of a pre-determined fraction of the amount lost. The wallet holder has to pay the insurance premium.
  10. It would be issued by the central bank as it is done today.
  11. It would retain the anonymity of cash to a large extent- but theoretically for a given transaction payer and recipient’s identity can be found out.
  12. There would be almost instant authentication of any transaction without any third party verification. The central bank would take the responsibility of authentication without any manual intervention. The process would be almost instantaneous as it happened in the use of debit card today.
  13. It would run parallel to paper currency till such time the share of paper currency becomes negligible
  14. It would be a legal tender with the rider that if the recipient of a transaction is not ready to accept digital currency, the payer has to pay the former with paper currency.
  15. All government agencies would have the infrastructure to receive digital currency. No government agency or a public utility would not be able to deny any digital currency transaction if the counterparty insists on that form of transaction. Thus a citizen would be able to buy a bus or metro ticket with digital currency. Taxes also can be paid by digital currency.
  16. A bank account holder can go to a bank branch or an ATM and would be able to load digital currency in her wallet as if physical cash is being dispensed as it happens today.
  17. With the consent of its employees, an employer can pay wages or salaries in the form of digital currencies. Government would prefer to give subsidies through digital currencies.
  18. Digital currencies would not work outside the jurisdiction of the issuing central bank. Thus it is a legal tender within the country of issuing central bank.
  19. A foreign citizen can exchange foreign currency with digital currency as long as he or she gets the wallet downloaded from the issuing central bank’s portal. The only restriction is that if the wallet is used for transaction outside the issuing central bank’s jurisdiction, it would not be authenticated. A money changer can exchange foreign currency (paper form) with domestic digital currency.
  20. No transaction fee is to be paid for using digital currency
  21. The central bank would be free to issue digital currency of any amount as it happens today.

Is it possible to have CBCC with all the above features? Surely it is possible using the same technology that Bitcoin uses, with some tweaking. In my next post I will outline a high level   design of such a system. I am confident that it should be possible to develop such a system which would not allow double spending and provide a very high level of anonymity to transactors and their transactions.

Bitcoin- Comment on Aswath Damodaran’s Post

Prof Aswath Damodaran (AD, henceforth) is a well-known name in the field of corporate finance and valuation of financial products. It is unfortunate that despite his formidable reputation in valuation of financial products, his latest “Musing on market” is a complete let down (You can read complete post here). He starts the blog by classifying investment assets into four categories. These are: Cash generating assets, Commodity, Currency and Collectibles. The first three categories do not need any clarification. But what about Collectibles? Picasso’s paintings fall into this category because they do not generate cash and, therefore, cannot be valued but it has a price. So, according to AD, something may have price but no value. For him “value” is synonymous with discounted future cash flow that an asset generates. So if an asset does not generate future cash flow, then it has no computable “present value” or “value”.  This definition of value is a highly myopic interpretation of notion of “value” that has been debated from the time of Adam smith to Gerard Debreu. This apparent distinction between price and value leads him to differentiate between trading and investing. The only difference between a trader and an investor is that they make different intertemporal choices.  An investor in collectibles has a choice to sell it immediately or sometimes in future. It follows logically that he finds that it is worthwhile to wait to get a higher price in future. Or he may get more pleasure holding it for a long time to come. The DCF valuation that financial instruments are subjected to, can be looked upon an estimate of the future market price. That is why; there is a market of financial instruments. If DCF is a correct estimate of “value” of any financial instrument then there is no reason why every dealer of a treasury would not have the same opinion about the intrinsic value of that instrument. If every trader has the same opinion would the market exist? According to him, traders do not bother about value but they only concerned about price. This begs the question – how price is determined in financial market?

Although we are really not concerned about the distinction between value and price, the issue becomes relevant in the context of Bitcoin- the subject matter of AD’s blog. Per force, AD has to categorize Bitcoin per his own classification scheme. Bitcoin does not generate cash; it is not a commodity too. So we are left with only two categories for Bitcoin to be slotted. AD now considers the definitional attributes of a currency.   These are well accepted and standard- unit of account, medium of exchange and store of value. Surprisingly AD finds that Bitcoin satisfies all the criteria to be designated as currency.  According to AD, anything which is fungible, divisible and countable can qualify to be a candidate “unit of account”.  If this is true, then theoretically any currency in any jurisdiction can function as currency. In fact, in some African countries, many small shops quote their merchandise in USD terms. But their balance sheets have to be prepared in terms of domestic currencies as per the law of the country. The acid test of anything to qualify as currency is that whether one can pay tax with that thing or not. AD gives three reasons for Bitcoin’s failure to take off as the preferred currency for majority of people. These are: – inertia, price volatility and competing crypto currency. He fails to note the most important reason- no sovereign backing. We have heard of dollarization of many domestic currencies because of people’s lack of trust on the domestic sovereign’s ability to preserve the purchasing power of that currency. But we must note that in no case people of such country start using the neighboring country’s currency, which could be as inflation prone as the former. In other words, backing of a powerful and trustworthy sovereign engenders the trust that is required for something to function of currency. The properties “medium of exchange “and the “store of value” neither jointly nor severally can make anything – real or virtual- a unit of account.

The problem with the ongoing effort to declare Bitcoin as currency is rooted in this historically untenable proposition that money originated from the act of barter. There is enough anthropological and numismatic evidence to the contrary. The renowned numismatist P. Grierson gave the simplest definition of money – ‘all money that is not coin or, like modern paper money, a derivative of coin’.  Historically, coins were always associated with an issuing authority. Thus sovereign backing is a prerequisite for something to become money in a specific jurisdiction.

So Bitcoin is not a currency or money proper. Of course, we can argue that the community of Bitcoin coin users can be considered as forming a “jurisdiction”. The “Bitcoin” is a currency of that virtual jurisdiction. But then Bitcoin can be considered as a currency of only that country. Then, the population size of that country would be smaller than Democratic Republic of São Tomé and Príncipe (200K) of West Africa.  The currency of that country, Dobra, suffered so much depreciation that the government had to issue a new Dobra in exchange of 1000 earlier Dobra. No foreign exchange trader has ever considered Dobra as a tradeable instrument. Bitcoin is experiencing appreciation of similar magnitude and, therefore, people are considering it as a lucrative financial asset. But to consider Bitcoin as a tradeable instrument would be blasphemous in the rarefied group of forex traders. AD, of course, suggests exactly the same in regard to Bitcoin.

It might be fashionable to hold an extreme libertarian view in the current dispensation of USA. In that environment, as the then Citigroup Chief Chuck Prince told in an interview, just when sub-prime crisis was knocking at the door of wall Street – “when the music stops, in terms of liquidity, things will be complicated. But as long as the music is playing, you’ve got to get up and dance. We’re still dancing”. This was on July 10, 2007. On October 5, Merrill Lynch announced a US$5.5 billion loss, revised it to $8.4 billion on October 24. We hope that gullible investors awash with liquidity do understand that music is bound to stop sometime and who knows who would be standing without a chair then.
