Bitcoins volatility arbitrage

Hence, there is no central bank or any other single intermediary involved and transactions are verified by a network of nodes that check the accuracy of the latest transaction against their register of total transactions, called the blockchain. The transaction is subsequently added to the ledger, and information is redistributed to other nodes. Footnote 1. This is one fundamental difference. Footnote 2 Bitcoins are mined by providing network services like verifying and collecting newly broadcast transactions which are added to a block.

In order for a block to be accepted in the network, miners have to provide proof of authenticity by finding a specific number called a nonce. A hash function which maps the nonce back to an easily verifiable bit string ensures that the block is valid cp. Antonopoulos As of August 31, , there were They amounted to a total market value of billion USD.

While the number of bitcoins has increased steadily since its introduction, demand and, thus, market value, has also increased albeit less steadily. For example, during the price for one Bitcoin increased from less than 1, US dollars to more than 19, US dollars and fell back to 8, US dollars by mid of Total Number of Bitcoins and Market Capitalization.

The figure presents the total number of Bitcoins in circulation dotted line, left axis and the market capitalization in million USD solid line, right axis from March 1, to September 9, In light of this high volatility, many people have questioned whether Bitcoin can ever fulfill the tasks of a currency.

Aiming to avoid the excessive volatility of cryptocurrencies while preserving the benefits of the blockchain technology led to the concept of low volatility stablecoins Lyons and Viswanath-Natraj ; Eichengreen like Tether Tether Operations Ltd. Also, a consolidated tape is not available albeit all markets trade the same object.

The minimum tick size during the sample period is subject to change as the exchanges adjust it in response to the Bitcoin price. Transaction fees are charged by the different platforms as a percentage of total transaction volume. For example, BitStamp charges between 0. Kraken additionally distinguishes between order types and submitting a market order is slightly more costly than submitting a limit order.

There may be additional fixed costs for wire transfers or other services provided. A critical issue in the Bitcoin framework is the regulation of cryptocurrencies which is heterogeneous across countries. In some jurisdictions, Bitcoin is completely banned e. In between these extremes are countries like Bahrain or Qatar which tolerate that their citizens use Bitcoin abroad, but not within the country Global Legal Research Center In addition to restrictions of use, treatment of gains for tax purposes also varies greatly.

In general, Bitcoin transactions are free from VAT, but gains are subject to tax. It is interesting to note that even the definitions vary across countries and have changed over the years, e. Recently, regulation of cryptocurrencies has been again in the focus of law-makers and central banks following the proposal of Facebook, Inc. They conclude that a stablecoin of global importance might endanger financial stability in case of malfunctions.

In contrast, Baughman and Flemming conclude that the demand for a global stable coin would be so low that there is no risk for the global financial system. However, it is not easy to predict the demand for such products. Consider again Fig. However, starting from , and thus four years after the introduction, the global demand started to rise and Bitcoin became recognized as the first and biggest global cryptocurrency.

For example, Kraken has been the target of multiple distributed denial of service DDoS attacks e. In the absence of binding regulation, it is unclear whether the exchange should be held accountable in such a situation when trading is made impossible.

Exposure to this kind of risk is potentially reflected in the volatility of Bitcoin prices. We analyze this issue in more detail in Sect. In our analysis, we use historical price time series obtained from two different sources.

The dataset of Bitcoin prices across different markets is obtained from investing. It covers daily open, high, low, and close prices for Bitcoin traded against the U. The sample starts April 1, for the Kraken and Bitfinex data, as well as the euro and yen exchange rates against the US dollar. Bitcoin data are available on a daily basis, FX data from Monday to Friday.

All time series are available until August 30, As not all of these markets were operational during the entire period since the introduction of Bitcoin, we also source a long time series of Bitcoin prices from bitinfocharts. The data cover the period July 17, until August 30, and are sampled on a daily frequency. Market information Bitcoin market capitalization and number of coins in circulation is obtained from blockchain.

These data start in March and also go till August 30, As a nonparametric measure of volatility, we rely on the estimator of Garman and Klass which reads as follows:. It is immediately apparent that Bitcoin volatility is much higher than the volatility of the FX rates. The plots also suggest that the volatility of volatility is higher in the Bitcoin case. This observation holds across all Bitcoin markets and all currencies against which Bitcoin is traded.

Volatility Time Series. The figure presents time series of daily volatility in percent from January 1, to January 25, for the six Bitcoin markets and the two foreign exchange markets. As can be seen, the average return of Bitcoin is similar across five out of the six markets. The slightly negative return observed on BTCBOX is due to the fact that the time series for this market only starts in January , amidst the downturn period after the all-time high in December The minimum values, however, are similar across all markets, reflecting the sharp downturn in March In contrast, the FX rates are rather stable across the sample period with an average return close to zero and an average volatility estimate below 0.

Also, the volatility of volatility is much lower in case of the FX rates as can be seen from the standard deviation of volatility which is times higher for Bitcoin than for the FX rates. High volatility in general in connection with the high volatility of volatility fosters extreme price fluctuations which are frequently observed in the Bitcoin market. It turns out that none of the time series exhibits a structural break. In order to assess the development of volatility over a long time period, we estimate an AR 1 -GARCH 1,1 model Bollerslev with t -distributed innovations on our long daily price time series.

As can be seen, the volatility has been higher at the beginning of the sample period than toward the end. Ultimately, this would be good news for the potential of evolving as a stable currency. However, the initial downward trend does not persist across the entire sample period. Considering the whole period from to , we observe a slight downward trend which, in a regression of volatility on time, even turns out statistically significant, albeit economically weak with 0.

This trend stopped after the first hype of Bitcoin at the end of Considering volatility between and , a similar trend regression leads to the conclusion that volatility is constant throughout these years, i. Trend in Volatility. The figure presents volatility of Bitcoin over time with two time trends: blue covers the entire period from July to August and brown starts January and ends August A final aspect which we want to highlight is the question how the markets covary.

This is important as the price difference between platforms trading Bitcoin can be substantial. If the information dissemination between markets works well, the pairwise correlation between daily transaction returns on those exchanges should be high as they all trade the same good Bitcoin. This is in general supported by our data. The correlations of Bitcoin returns are high in general 0. In addition, they are higher than the correlation of the FX returns which is on average 0.

Still, the correlations only tend to converge to one at the end of the sample period, irrespective of whether Bitcoin is traded in the same currency e. This observation also holds for the remaining unreported combinations. The bottom left graph in Fig. On average, the correlation across time is 0. Return Correlations. The graph presents the dynamic conditional correlation of the daily return time series in the named markets.

The evolution of Bitcoin return correlations has important implications in terms of market efficiency. In an efficient market setup, one should be able to construct a roundtrip. The cost to implement this trading strategy should be equal to the bid-ask spread plus some cost that may be involved when changing the trading venue. Put differently, if there are arbitrage gains to be made by buying in one market and selling in another market, prices should adjust to the fundamental value.

In a fully electronic market, this should happen quickly and ultimately lead to high correlations of price changes. In the Bitcoin setup, there seem to be opportunities for arbitrage gains, in particular at the beginning of the sample period, when the correlation was sometimes very low. This finding is in line with Shynkevich who reports that arbitrage gains are more difficult to realize since This is the period when the correlation tends toward one in Fig.

This section analyzes the volatility of Bitcoin in crises, its role as a risk-diversifier in a portfolio, its similarity with major currencies, and its role as a medium of exchange and a store of value. An important question concerning the volatility of Bitcoin is how it behaves during crises. There are two sorts of crises which we distinguish. First, we have crises related to the Bitcoin market itself.

These are the named DDoS attacks or hacks of exchanges. On the other hand, Bitcoin could also be related to the real economy and volatility might therefore be linked to the stock market. Since the data covers the COVID pandemic and thus the first financial crisis since the inception of Bitcoin in late , the analysis can provide some unique insights. This is also related to the question whether Bitcoin is a safe haven which is impossible to test if there is no crisis as explained by Smales To test whether the volatility behaves differently in any of the two circumstances, we implement a GARCH 1,1 model Bollerslev using daily data from coinmarketcap.

For precise crisis dates in the latter case, we use the end of February until the end of May , inspired by the time when the stock market plummeted and rebounded. However, the order of magnitude is non-negligible as the unconditional variance is more than 10 times higher under attacks than usual. While the parameter estimate suggests an increase, it is not statistically significant. To check the robustness of this finding, we also use March 31, , as the end of the COVID crisis, and the results are qualitatively identical; the parameter for the COVID crisis never turns out statistically significant.

The correlations are positive and thus different compared with previous findings. The correlations increase from 0. The optimal minimum variance weights of Bitcoin are 2. The higher correlation estimates for monthly and quarterly returns increase the variance by too much for weights to be larger than zero.

The non-monotonicity of the weights is due to a deteriorating risk-return ratio of Bitcoin from daily to monthly return frequencies. The differences between the two optimization criteria are intuitive as the minimum variance portfolio is exclusively based on variances and covariances and thus ignores the estimated expected returns, whereas the optimal Sharpe ratio portfolio includes the latter and the high returns appear to dominate the variance resulting in much higher weights of Bitcoin compared with the minimum variance portfolios.

Given the evolution of Bitcoin and its youth, it is well possible that specific characteristics will change in the future. Hence, we briefly analyze the sensitivity of the estimates with regards to the portfolio weights. If the expected returns decreased, e. Its excess volatility implies very low or zero weights in a minimum variance portfolio. For Bitcoin to serve as a currency, it must resemble established, major currencies such as the US dollar.

We operationalize resemblance with two key features, namely integration in the global currency system and stability. This leads to the following hypotheses. Under H1, Bitcoin is integrated into the global FX market. Hence, if Bitcoin is part of the global system of exchange rates, it would need to be affected at the same time and of a similar order of magnitude, resulting in a strong comovement of its volatility with the volatility of other FX rates.

Under H2, Bitcoin is relatively stable. If the volatility of Bitcoin is not different from the volatility of major exchange rates, Bitcoin is a reliable currency, i. To test H1, we compute a DCC model Engle for all possible volatility pairs and extract the time series of conditional correlations. In a second step, we test whether the correlation of Bitcoin volatility and FX volatility is, on average, as high as the correlation of the two FX volatility time series.

The latter serves as a benchmark for volatility correlation in the FX market and allows us to quantify the expected level of the correlation. The correlation between the two FX rates is on average 0. The fact that Bitcoin volatility is different is already illustrated by the correlation between Bitfinex and Kraken volatility which is on average higher 0. In order to test H 1, we focus on the correlation between Bitfinex and the two FX rates. As can be seen from Fig.

It therefore comes as no surprise that a two-sample t test rejects H 1 at any significance level for the pairs depicted in Fig. Hence, we reject the hypothesis that Bitcoin is well-integrated in the global FX market. Volatility Correlations. The figure presents the dynamic conditional correlation of volatility in the named markets. H 2 suggests that in order for Bitcoin to be a currency, its price fluctuations should not be greater than the fluctuation of major exchange rates involving the US dollar, the euro and the yen.

We implement the test as a two-sided two-sample Wilcoxon test to account for the fact that the volatilities are not normally distributed. The alternative hypothesis is that the means are different. Hence, we conclude that Bitcoin volatility is different from the volatility of the three major currencies. A further way to establish whether Bitcoin is integrated in the fiat currency system is to calculate the Bitcoin implied exchange rate. It is obtained as the ratio of Bitcoin prices traded against the currencies of interest.

Seen as a cost, this might be better than the large spread offered by banks. This is a particular problem during the early part of the sample. Bitcoin implied exchange rates. The figure presents the exchange rate between the Euro and the U. Here, in particular the period at the end of shows remarkable differences. Hence, it seems that there are periods in Bitcoin trading when the price rises substantially, potentially beyond any reasonable fundamental estimate, and the link between the markets gets weaker and the relation to the exchange rate is broken.

However, for Bitcoin to be integrated into the foreign exchange markets, one would require a reliable, stable relationship so that exchanging money could go through any channel without the risk of significant losses. This section analyzes whether the three key properties of a currency, namely medium of exchange, unit of account, and store of value, also hold for the cryptocurrency Bitcoin. Currently, if a transaction is supposed to be carried out in Bitcoin, the buyer would have to buy Bitcoin first before using it for payment.

Subsequently, it is most likely that the seller converts Bitcoin back to the local currency in order to pay his creditors. Such a transaction, however, bears exchange rate risk which increases with the level of volatility in the Bitcoin exchange market.

For example, Fig. A few days of Bitcoin prices. The figure presents the Bitcoin price in USD from March 11 to March 20, in transaction time using every fourth observation in the plot to reduce size. To give a more precise example, consider the period 11 to March 13, which is depicted in Fig. The graph presents the time series of high frequency trading prices of Bitcoin on Kraken for these days.

Now imagine that a coffee shop sells a cup of coffee for , Satoshi Footnote 8 which, on March 10 and 11, at 7. On the morning of March 12, your daily morning coffee got a bit cheaper and is now 4. Even worse, at lunchtime, the same coffee sells for 3. For the coffee shop owner, that is an unsustainable situation as she would have to incur huge losses if prices stay that low.

To still earn 5 USD, the coffee shop owner would have had to increase the price to 1,, Satoshi on March 13, doubling the price. This example also highlights the inconsistent news regarding the acceptance of Bitcoin by small and large corporations. Economic reasoning and intuition helps to understand that it would be very costly for any corporation, be it Apple, Dell, Microsoft, or Paypal, to accept Bitcoin as a means of payment.

What some firms may offer as a payment option is the conversion of Bitcoin through a linked Bitcoin exchange. This is similar to making a payment in foreign currency which is converted into local currency at the time of the transaction. Consequently, the conversion is generally costly and thus much more expensive than an actual and direct payment in Bitcoin would be. The only way to entirely remove this risk would be for a country to adopt Bitcoin as a currency and restrict the exchange of Bitcoin into other currencies.

But there are no reasons for a developed country to adopt Bitcoin as its currency since it would give up all control over its money supply. That is why the central banks of several countries, instead of adopting Bitcoin, consider creating their own digital currencies.

Footnote 9. White argues that the unit of account and the medium of exchange feature cannot be separated. In the current state where Bitcoin is not accepted widely by buyers or sellers as a means of payment, trading partners suffer additional costs direct costs from exchanging currencies and indirect costs due to the high fluctuation of Bitcoin when using Bitcoin as a unit of account. As Bitcoin is currently not accepted as a medium of exchange, it cannot have the unit of account feature.

Furthermore, due to its extreme volatility it is difficult or impossible to derive the true value of a specific good measured in Bitcoin. It is therefore not useful as a unit of account. Yermack states that the only way to solve this issue is for a country to adopt Bitcoin as principal currency. Subscribe to , Subscribe. Source: CoinDesk Research.

Yermack states that the only way to solve this issue is for a country to adopt Bitcoin as principal currency. However, this is an unlikely scenario at least for a large country as discussed in Sect.

Our analysis so far has identified excess volatility of Bitcoin which appears to reject its use as a store of value. However, since the long-term price trend is clearly positive as shown in Fig. In other words, since Bitcoin cannot be inflated beyond a fixed cap, unlike gold whose supply is not fixed, it is possible that demand growth will persistently exceed supply growth in the future. Long-term price trends.

The figure presents the evolution of the price of Bitcoin solid line and long-term trends based on 1-year, 2-year, and 3-year moving averages MA. The following equation describes the relation of demand and supply of a currency cp. Sachs and Larrain , ch.

If V is constant and M grows at a lower rate than Y , P must fall implying deflation. The value of one unit of currency M would be inversely related to the price level P , i. Footnote 10 In this deflationary scenario, currency holders have an incentive to hoard money and delay spending. This scenario is consistent with the long-run positive price trend of Bitcoin and with Bitcoin being a store of value.

Interestingly, major fiat currencies and gold are considered stores of values despite their price fluctuations and differing price trends. The price of gold appreciated relative to major currencies over the last 40 years due to inflation of consumer prices in fiat currencies. Consequently, fiat currencies depreciated against gold and many other real assets over the last 40 years.

These examples emphasize that the price of a store of value in many cases is not and need not be stable. The long-term store of value property can also be illustrated differently, based on the holding period returns of Bitcoin. We calculate the log-returns of holding Bitcoin on a monthly basis for various buy and sell time periods between April and July The result is presented in Fig.

Indeed, only an investment during the high value period in December leads to a negative holding period return over all horizons. Investment triangle. The figure presents the holding returns of Bitcoin over time when investing on the first of the month and selling at the end of the month named on the y-axis and x-axis, respectively. Bitcoin is a cryptocurrency but does not work as a currency due to its excess volatility. The high volatility makes it prohibitively costly to use as a medium of exchange and a unit of account.

This conclusion holds for very short time horizons, e. In contrast, over very long horizons, Bitcoin can be considered a store of value despite its excess volatility. There are many historical examples of hyperinflation and currency crises with extreme changes in currencies similar to changes in the value of Bitcoin. In these cases, the currencies were often replaced by barter or alternative foreign currency.

While such fiat currencies often continued to serve as official money despite the extraordinary high volatility, there is a fundamental difference between traditional fiat currencies and Bitcoin. The former are backed by a state and require tax payments in the state-issued currency creating a direct demand for this currency see Goodhart Without this requirement, a highly volatile currency, such as Bitcoin, is unlikely to be used as a means of payment.

Since Bitcoin is independent of any government which may require payments in Bitcoin, people have a choice which translates into the freedom to not use it as a medium of exchange. Despite its high historical volatility compared to major currencies, Bitcoin may evolve as a store of value and an alternative to other stores of value such as gold.

Both the deflationary design and the decentralized and global nature enhance the store of value property and in turn make it unlikely that any country will adopt it as an official currency and thus lose control over the money supply and its monetary policy. Excess volatility appears to be inconsistent with a store of value but if the store of value is volatile only in the short run but relatively stable or rising in the long run, volatility may not be the major issue for Bitcoin as a store of value.

After all, safe assets are also volatile and risky until maturity. And fiat currencies are not safe or risk-free either. Due to inflation, most fiat currencies have depreciated against real assets such as gold or housing and thus did not work as a store of value in the long run but only in the short run.

This is in contrast to Bitcoin which does not work as a store of value in the short run but potentially in the long run. The creation of new Bitcoin, called mining, resembles the mining of gold. Gold, similar to Bitcoin, is not a generally accepted unit of account and medium of exchange. An obvious and key difference of gold and Bitcoin is that the former is a tangible, physically mined commodity, whereas the latter only exists digitally.

There are two instances where the estimator becomes negative, probably due to wrong recordings of the data. In this instance, we only use half the square of the h and l range as a proxy for the daily variance following Martens and van Dijk To check the persistence of the volatility time series, we estimate the fractional integration parameter d using the methodologies proposed by Geweke and Porter-Hudak and Shimotsu and Phillips We use the events listed in Twomey and Mann where we were able to identify the exact dates.

Governments and central banks could create digital currency and then peg the digital currency to the existing fiat currency Eichengreen ; Mersch In this case, a regulated exchange would be required to use the pegged exchange rate to convert fiat currency into digital currency or vice versa.

Now we come to the second risk of bitcoin arbitrage: Exchange withdrawal issues. This is another layer of danger which inexperienced users usually overlook when thinking about arbitrage. Simply put, the exchanges withhold the right — at least Cryptsy does — of doing whatever they want with their withdrawal services.

The wannabe did as the program said, and sent his precious bitcoin to the exchange; where he bought the InfiniteCoin he needed, with every fee already taken care of in his calculations. IFC had a block time of 30 seconds — that meant the transaction is supposed to take that amount of time to be confirmed. The amateur arbitrageur waited 30 seconds, and he began thinking that it must be some administrative issue.

By then though the arbitrage opportunity was lost. Twelve days later, and after several support tickets, the coins were at last transferred. Not only did the opportunity of profit pass, but the coins were more or less worthless by the time they were traded. Experienced arbitrageurs already know this, in these cases the arbitrage opportunity is inexistent.

How do they know? Well, to shed some light on it, sometimes the price is low not because the sellers are mis-pricing it, but because the exchange is broken, and they want their money out. There are many ways to do arbitrage with bitcoin, and other crypto-currencies, and they depend on several questions:. While it is easy to imagine buying at a discount on one place and selling at a premium on another, it is not as intuitive to think about already having your funds there. This is our first arbitraging method.

Since it is difficult to reliably predict which currencies will have arbitrage opportunities in the often volatile markets, you would need to study the currencies for trends of potential arbitrage. The biggest drawback this method has is that the volatility risk might eliminate your gains from arbitrage. Requiring 2x the money involved in the transaction is not as big a disadvantage as it may seem, since current arbitrage opportunities are small.

If you are keen on taking transaction risks, you might as well perform the second arbitraging method. This is what everybody thinks when they first learn about crypto currency arbitrage. You buy cheaply on Exchange A and then you sell it at a higher price on Exchange B. Also, this does not mitigate the volatility risk you will incur by holding cryptocurrencies.

This may change though in the future with cryptocurrencies as they stabilize. Sometimes it is not a matter of buying apples at a low price and selling them at a premium elsewhere. Sometimes you buy apples to exchange for oranges and then exchange those oranges for bananas, which you then trade for apples again. Triple arbitrage takes advantage of price discrepancies amongst different trade-able objects. It is unlikely and much riskier that anyone performs triple arbitrage without automated means, the barrier of entry is also much higher than the two previous methods with a single trading pair.

While you might be able to use more than three pairs to trade, the possibilities of doing so diminish due to trading fees. We should carry on to the next question, which mitigates a risk that every method above has. If you believe bitcoin will continue to acquire value in the future, you are thinking in this same mindset — your investment is its own holdings, rather than taking advantage of a market discrepancy.

But in the volatile world of crypto currency arbitrage, you might not necessarily want to go long with Bitcoin depending on your feelings of the market. The volatility for the five year old currency is high and any gains that you acquire from arbitrage are not stable. A mere ten percent gain or loss on the value of Bitcoin could double or destroy your gains from the arbitrage methods listed earlier in this article.

By staying in a stable, government-backed currency such as the US dollar, you can meanwhile get into an exchange, trade for your profit, and get out. There surely are variations and increasingly complex ways of conducting arbitrage, for instance instead of triple-arbitrage, quadruple and quintuple-arbitrage.

These methods listed above are, at a glance, how to approach arbitrage with Bitcoin and other cryptocurrencies on the market. In my opinion, the landscape for arbitraging is not easy — Take it from someone who thought it would be profitable and went through the effort of developing software exactly for arbitrage.

I could be proven wrong, but I would need to see data to believe it; just as I needed data to conclude the great risk of arbitrage at this time. What is Arbitrage? Why does it happen? Is it hard? The scenario: Buy InfiniteCoin at Cryptsy, then sell it. InfiniteCoin withdrawals are taking infinite time. So how do you do bitcoin arbitrage? There are many ways to do arbitrage with bitcoin, and other crypto-currencies, and they depend on several questions: Will I have to move my currency between exchanges or are they already there?

Will I trade a single pair or several? Which currency will I end up with? Something else? The evolution of Bitcoin return correlations has important implications in terms of market efficiency. In an efficient market setup, one should be able to construct a roundtrip. The cost to implement this trading strategy should be equal to the bid-ask spread plus some cost that may be involved when changing the trading venue. Put differently, if there are arbitrage gains to be made by buying in one market and selling in another market, prices should adjust to the fundamental value.

In a fully electronic market, this should happen quickly and ultimately lead to high correlations of price changes. In the Bitcoin setup, there seem to be opportunities for arbitrage gains, in particular at the beginning of the sample period, when the correlation was sometimes very low. This finding is in line with Shynkevich who reports that arbitrage gains are more difficult to realize since This is the period when the correlation tends toward one in Fig.

This section analyzes the volatility of Bitcoin in crises, its role as a risk-diversifier in a portfolio, its similarity with major currencies, and its role as a medium of exchange and a store of value. An important question concerning the volatility of Bitcoin is how it behaves during crises. There are two sorts of crises which we distinguish. First, we have crises related to the Bitcoin market itself. These are the named DDoS attacks or hacks of exchanges.

On the other hand, Bitcoin could also be related to the real economy and volatility might therefore be linked to the stock market. Since the data covers the COVID pandemic and thus the first financial crisis since the inception of Bitcoin in late , the analysis can provide some unique insights.

This is also related to the question whether Bitcoin is a safe haven which is impossible to test if there is no crisis as explained by Smales To test whether the volatility behaves differently in any of the two circumstances, we implement a GARCH 1,1 model Bollerslev using daily data from coinmarketcap.

For precise crisis dates in the latter case, we use the end of February until the end of May , inspired by the time when the stock market plummeted and rebounded. However, the order of magnitude is non-negligible as the unconditional variance is more than 10 times higher under attacks than usual.

While the parameter estimate suggests an increase, it is not statistically significant. To check the robustness of this finding, we also use March 31, , as the end of the COVID crisis, and the results are qualitatively identical; the parameter for the COVID crisis never turns out statistically significant. The correlations are positive and thus different compared with previous findings. The correlations increase from 0. The optimal minimum variance weights of Bitcoin are 2.

The higher correlation estimates for monthly and quarterly returns increase the variance by too much for weights to be larger than zero. The non-monotonicity of the weights is due to a deteriorating risk-return ratio of Bitcoin from daily to monthly return frequencies. The differences between the two optimization criteria are intuitive as the minimum variance portfolio is exclusively based on variances and covariances and thus ignores the estimated expected returns, whereas the optimal Sharpe ratio portfolio includes the latter and the high returns appear to dominate the variance resulting in much higher weights of Bitcoin compared with the minimum variance portfolios.

Given the evolution of Bitcoin and its youth, it is well possible that specific characteristics will change in the future. Hence, we briefly analyze the sensitivity of the estimates with regards to the portfolio weights. If the expected returns decreased, e. Its excess volatility implies very low or zero weights in a minimum variance portfolio. For Bitcoin to serve as a currency, it must resemble established, major currencies such as the US dollar. We operationalize resemblance with two key features, namely integration in the global currency system and stability.

This leads to the following hypotheses. Under H1, Bitcoin is integrated into the global FX market. Hence, if Bitcoin is part of the global system of exchange rates, it would need to be affected at the same time and of a similar order of magnitude, resulting in a strong comovement of its volatility with the volatility of other FX rates. Under H2, Bitcoin is relatively stable. If the volatility of Bitcoin is not different from the volatility of major exchange rates, Bitcoin is a reliable currency, i.

To test H1, we compute a DCC model Engle for all possible volatility pairs and extract the time series of conditional correlations. In a second step, we test whether the correlation of Bitcoin volatility and FX volatility is, on average, as high as the correlation of the two FX volatility time series. The latter serves as a benchmark for volatility correlation in the FX market and allows us to quantify the expected level of the correlation. The correlation between the two FX rates is on average 0.

The fact that Bitcoin volatility is different is already illustrated by the correlation between Bitfinex and Kraken volatility which is on average higher 0. In order to test H 1, we focus on the correlation between Bitfinex and the two FX rates. As can be seen from Fig.

It therefore comes as no surprise that a two-sample t test rejects H 1 at any significance level for the pairs depicted in Fig. Hence, we reject the hypothesis that Bitcoin is well-integrated in the global FX market. Volatility Correlations. The figure presents the dynamic conditional correlation of volatility in the named markets. H 2 suggests that in order for Bitcoin to be a currency, its price fluctuations should not be greater than the fluctuation of major exchange rates involving the US dollar, the euro and the yen.

We implement the test as a two-sided two-sample Wilcoxon test to account for the fact that the volatilities are not normally distributed. The alternative hypothesis is that the means are different. Hence, we conclude that Bitcoin volatility is different from the volatility of the three major currencies. A further way to establish whether Bitcoin is integrated in the fiat currency system is to calculate the Bitcoin implied exchange rate.

It is obtained as the ratio of Bitcoin prices traded against the currencies of interest. Seen as a cost, this might be better than the large spread offered by banks. This is a particular problem during the early part of the sample. Bitcoin implied exchange rates. The figure presents the exchange rate between the Euro and the U. Here, in particular the period at the end of shows remarkable differences.

Hence, it seems that there are periods in Bitcoin trading when the price rises substantially, potentially beyond any reasonable fundamental estimate, and the link between the markets gets weaker and the relation to the exchange rate is broken. However, for Bitcoin to be integrated into the foreign exchange markets, one would require a reliable, stable relationship so that exchanging money could go through any channel without the risk of significant losses.

This section analyzes whether the three key properties of a currency, namely medium of exchange, unit of account, and store of value, also hold for the cryptocurrency Bitcoin. Currently, if a transaction is supposed to be carried out in Bitcoin, the buyer would have to buy Bitcoin first before using it for payment. Subsequently, it is most likely that the seller converts Bitcoin back to the local currency in order to pay his creditors. Such a transaction, however, bears exchange rate risk which increases with the level of volatility in the Bitcoin exchange market.

For example, Fig. A few days of Bitcoin prices. The figure presents the Bitcoin price in USD from March 11 to March 20, in transaction time using every fourth observation in the plot to reduce size. To give a more precise example, consider the period 11 to March 13, which is depicted in Fig. The graph presents the time series of high frequency trading prices of Bitcoin on Kraken for these days. Now imagine that a coffee shop sells a cup of coffee for , Satoshi Footnote 8 which, on March 10 and 11, at 7.

On the morning of March 12, your daily morning coffee got a bit cheaper and is now 4. Even worse, at lunchtime, the same coffee sells for 3. For the coffee shop owner, that is an unsustainable situation as she would have to incur huge losses if prices stay that low.

To still earn 5 USD, the coffee shop owner would have had to increase the price to 1,, Satoshi on March 13, doubling the price. This example also highlights the inconsistent news regarding the acceptance of Bitcoin by small and large corporations. Economic reasoning and intuition helps to understand that it would be very costly for any corporation, be it Apple, Dell, Microsoft, or Paypal, to accept Bitcoin as a means of payment.

What some firms may offer as a payment option is the conversion of Bitcoin through a linked Bitcoin exchange. This is similar to making a payment in foreign currency which is converted into local currency at the time of the transaction. Consequently, the conversion is generally costly and thus much more expensive than an actual and direct payment in Bitcoin would be.

The only way to entirely remove this risk would be for a country to adopt Bitcoin as a currency and restrict the exchange of Bitcoin into other currencies. But there are no reasons for a developed country to adopt Bitcoin as its currency since it would give up all control over its money supply.

That is why the central banks of several countries, instead of adopting Bitcoin, consider creating their own digital currencies. Footnote 9. White argues that the unit of account and the medium of exchange feature cannot be separated. In the current state where Bitcoin is not accepted widely by buyers or sellers as a means of payment, trading partners suffer additional costs direct costs from exchanging currencies and indirect costs due to the high fluctuation of Bitcoin when using Bitcoin as a unit of account.

As Bitcoin is currently not accepted as a medium of exchange, it cannot have the unit of account feature. Furthermore, due to its extreme volatility it is difficult or impossible to derive the true value of a specific good measured in Bitcoin.

It is therefore not useful as a unit of account. Yermack states that the only way to solve this issue is for a country to adopt Bitcoin as principal currency. However, this is an unlikely scenario at least for a large country as discussed in Sect.

Our analysis so far has identified excess volatility of Bitcoin which appears to reject its use as a store of value. However, since the long-term price trend is clearly positive as shown in Fig. In other words, since Bitcoin cannot be inflated beyond a fixed cap, unlike gold whose supply is not fixed, it is possible that demand growth will persistently exceed supply growth in the future.

Long-term price trends. The figure presents the evolution of the price of Bitcoin solid line and long-term trends based on 1-year, 2-year, and 3-year moving averages MA. The following equation describes the relation of demand and supply of a currency cp. Sachs and Larrain , ch. If V is constant and M grows at a lower rate than Y , P must fall implying deflation.

The value of one unit of currency M would be inversely related to the price level P , i. Footnote 10 In this deflationary scenario, currency holders have an incentive to hoard money and delay spending. This scenario is consistent with the long-run positive price trend of Bitcoin and with Bitcoin being a store of value.

Interestingly, major fiat currencies and gold are considered stores of values despite their price fluctuations and differing price trends. The price of gold appreciated relative to major currencies over the last 40 years due to inflation of consumer prices in fiat currencies. Consequently, fiat currencies depreciated against gold and many other real assets over the last 40 years. These examples emphasize that the price of a store of value in many cases is not and need not be stable.

The long-term store of value property can also be illustrated differently, based on the holding period returns of Bitcoin. We calculate the log-returns of holding Bitcoin on a monthly basis for various buy and sell time periods between April and July The result is presented in Fig.

Indeed, only an investment during the high value period in December leads to a negative holding period return over all horizons. Investment triangle. The figure presents the holding returns of Bitcoin over time when investing on the first of the month and selling at the end of the month named on the y-axis and x-axis, respectively.

Bitcoin is a cryptocurrency but does not work as a currency due to its excess volatility. The high volatility makes it prohibitively costly to use as a medium of exchange and a unit of account. This conclusion holds for very short time horizons, e. In contrast, over very long horizons, Bitcoin can be considered a store of value despite its excess volatility. There are many historical examples of hyperinflation and currency crises with extreme changes in currencies similar to changes in the value of Bitcoin.

In these cases, the currencies were often replaced by barter or alternative foreign currency. While such fiat currencies often continued to serve as official money despite the extraordinary high volatility, there is a fundamental difference between traditional fiat currencies and Bitcoin.

The former are backed by a state and require tax payments in the state-issued currency creating a direct demand for this currency see Goodhart Without this requirement, a highly volatile currency, such as Bitcoin, is unlikely to be used as a means of payment. Since Bitcoin is independent of any government which may require payments in Bitcoin, people have a choice which translates into the freedom to not use it as a medium of exchange.

Despite its high historical volatility compared to major currencies, Bitcoin may evolve as a store of value and an alternative to other stores of value such as gold. Both the deflationary design and the decentralized and global nature enhance the store of value property and in turn make it unlikely that any country will adopt it as an official currency and thus lose control over the money supply and its monetary policy. Excess volatility appears to be inconsistent with a store of value but if the store of value is volatile only in the short run but relatively stable or rising in the long run, volatility may not be the major issue for Bitcoin as a store of value.

After all, safe assets are also volatile and risky until maturity. And fiat currencies are not safe or risk-free either. Due to inflation, most fiat currencies have depreciated against real assets such as gold or housing and thus did not work as a store of value in the long run but only in the short run. This is in contrast to Bitcoin which does not work as a store of value in the short run but potentially in the long run. The creation of new Bitcoin, called mining, resembles the mining of gold.

Gold, similar to Bitcoin, is not a generally accepted unit of account and medium of exchange. An obvious and key difference of gold and Bitcoin is that the former is a tangible, physically mined commodity, whereas the latter only exists digitally. There are two instances where the estimator becomes negative, probably due to wrong recordings of the data.

In this instance, we only use half the square of the h and l range as a proxy for the daily variance following Martens and van Dijk To check the persistence of the volatility time series, we estimate the fractional integration parameter d using the methodologies proposed by Geweke and Porter-Hudak and Shimotsu and Phillips We use the events listed in Twomey and Mann where we were able to identify the exact dates.

Governments and central banks could create digital currency and then peg the digital currency to the existing fiat currency Eichengreen ; Mersch In this case, a regulated exchange would be required to use the pegged exchange rate to convert fiat currency into digital currency or vice versa.
