Holding Bitcoin Longer Part 2

< Holding Bitcoin Longer Part 1 


The rest of the paper is organized as follows: Section 2 reviews the literature and  develops a hypothesis; Section 3 describes data; Section 4 explains the methodology; Section 5 presents results; and Section 6 concludes.

2. Literature Review and Hypotheses

Bitcoin appeared in 2009 as the first cryptocurrency. It was created by an anonymous internet group operating under the pseudonym Satoshi Nakamoto and was initially introduced as an alternative to conventional currencies. Bitcoin is the most important of all virtual currencies because it held an 89% share of all virtual currency market capitalization as of December 2016 (Bariviera et al., 2017). Bitcoin prices over time are substantially more volatile than conventional currency. Blau (2017) suggests that the volatility of Bitcoin prices is double the average of the 51 regular currencies under their study from July 2010 to June 2014. Through correlation testing, Blau (2017) concludes that Bitcoin returns were unrelated to speculative trading. Differently, Cheah and Fry (2015) show that Bitcoin price exhibits speculative bubbles and the fundamental value of Bitcoin is zero.

Although it is a non-traditional currency Bitcoin has similarities with traditional currencies. Yermack (2013) evaluates the validity of Bitcoin as a currency against the three required functions of a currency. He states that although Bitcoin satisfies the function as a medium of exchange, it cannot be a store of value or a unit of account, which are two of the three attributes required when being considered a currency by economists. Dyhrberg (2016b) investigates whether Bitcoin more resembles a commodity or a currency. The author finds that Bitcoin returns have a significant positive reaction to the US Federal Funds rate, similar to the US dollar. Bitcoin is also found to provide risk-management capabilities against Dollar-Pound and Dollar-Euro exchange rates, similar to what researchers found in gold. Dyhrberg (2015b) concludes that Bitcoin can be classified as something in between the US dollar and gold as a commodity asset. Luther and Salter (2017) analyze the increase in Bitcoin app downloads after Cyprus bailout announcement. While Bitcoin app downloads increased in both the US and Cyprus after the bailout announcement, interest was greater in the US, possibly suggesting that Bitcoin is not replacing the currencies of countries with troubled banks. The other line of research analyzes Bitcoin’s hedging ability as an asset. Dyhrberg (2016a) used daily data from 2010 to 2015 to test Bitcoin’s hedging ability against some UKrelated assets including USD-EUR Exchange rates, USD-GBP Exchange rates, and the FTSE. The results showed that Bitcoin was uncorrelated to the FTSE Index in both lagged and contemporaneous returns, and is uncorrelated with Dollar-Euro and Dollar-Sterling contemporaneous returns, but is positively correlated to the lagged exchange rate returns. These indicate that Bitcoin could be a weak hedge against UK assets.

Bouri et al. (2017) hypothesized that Bitcoin could hedge negative movements in world stock indices (S&P 500, FTSE 100, DAX 30, Nikkei 225, Shanghai A-Share, MSCI, Bond, US dollar, and Commodity), gold prices, and oil prices. Using daily and weekly price index data from mid-2011 to end of 2015, their results indicated that Bitcoin had the ability to hedge against the Nikkei, the MSCI Pacific and commodity index as their coefficients were negatively correlated and significant. However, the significance of these coefficients faded when examining the weekly data. This is an example of how data frequency may change the hedging ability of Bitcoin.

Bouri et al. (2017) and Dyhrberg (2016a) demonstrate that Bitcoin possesses riskmanagement abilities against regional assets related to UK and Asia. Bouri et al. (2017) caution that the diversification ability of Bitcoin is not constant over time and future studies on the timevarying nature of these risk-management abilities are necessary. We will use more up-to-date data to investigate Bitcoin’s daily, weekly, and monthly hedging abilities against five major stock indices, i.e., the S&P 500, Nikkei, Shanghai A-Share, the TSX Composite Index, and the Euro Index. Two of these five indices (TSX and Euro index) haven not been studies by other research. Longer horizon investors would more likely require monthly data trends rather than daily or weekly analyses.

Bouri et al. (2017) and Dyhrberg (2016a) find that Bitcoin can hedge Asian and UK assets, but the hedging relationship fades with weekly data. Therefore, we formulate our hypotheses as follows:
H1: Bitcoin can hedge and diversify against certain assets among S&P 500, Nikkei, Shanghai A-Share, TSX Composite Index, and Euro Index.

H2: The hedging and diversification abilities of Bitcoin differ under different data frequencies.

3. Data

Bitcoin (BTC) daily price data from October 2010 (the earliest data available) to October 2017 was retrieved from the Coindesk Price Index (2017). We choose five indices, S&P 500 (GSPC), Nikkei (N225), Shanghai A-Share (SSE Composite), TSX Composite Index (GSPTSE) and Euro Index (STOXX50E), which represent different regions whose currencies top the share of Bitcoin trade. Bitcoin trading against the Chinese Yuan used to account for most of Bitcoin trading volume until China started to clamp down on digital currency exchanges in early 2017 and eventually banned the trading of Bitcoin in September of 2017. Japan’s Yen then took over as the regulators in Japan adopted digital currency-friendly rules. The US Dollar and Euro are also among the top five most active Bitcoin trading currencies (Russo and Migliozzi, 2017). Daily, weekly and monthly prices were sourced from Yahoo. Our sample consists of 1,828 observations for daily frequency, 366 observations for weekly frequency, and 85 observations for monthly frequency for all assets under study.

Is it better to trade bitcoins or mine them?

Bitcoin has continued to cause quite a stir, and interest in this cryptocurrency is increasing at an incredible rate. And no wonder, considering that the value of bitcoins has been soaring, reaching a record high in March 2017, when bitcoin value exceeded the price of an ounce of gold. However, for those fascinated with this revolutionary currency who are itching to become involved, one key question still remains: It is better to trade bitcoins or to mine them? To help answer this question, we shall explore the two options at length below.

A short history of bitcoin mining

Unlike others types of currency, bitcoin is not distributed and regulated by a central government. Each miner becomes directly involved by using a special software to solve math problems for which they receive a certain number of bitcoins as reward. However, the difficulty of the math problems varies depending on how quickly they are being solved in the bitcoin network. In the early days, miners used the processors in their computers to solve these problems. As bitcoin evolved, miners soon learned that graphic cards were more effective in this undertaking. However, graphic cards also required more electricity and generated more heat. These days, most miners invest in an ASIC, an application-specific integrated circuit chip, which has been specifically developed for bitcoin mining.


Bitcoin mining today.

Since bitcoin has continued to grow in popularity, more and more miners have joined the network. The result here has been that it has become increasingly difficult for individual miners to solve the math equations required to generate bitcoins, since they become more complex the larger the bitcoin network grows. To deal with this issue, many miners now work together in pools, and each miner is rewarded according to their specific efforts within the group. In addition, many individual bitcoin miners can no longer afford the equipment and time investment involved to mine on their own. However, even for mining companies and pools, one risky feature of bitcoin mining still remains: bitcoin halving.

What is bitcoin halving?

When mining bitcoins, miners create a ledger of previous transactions which create a chain of blocks known as a "blockchain". But these blockchains are not endless: Bitcoin's code requires the amount of bitcoins created to be halved once 210,000 blocks have been recorded. Although economists have many theories on what this might mean for bitcoin, one thing remains certain: halving is hardest on the miners themselves. The monetary base of bitcoins is set at 21 million bitcoins, and this amount can never be increased.

Adding new bitcoins can be costly in terms of time, electricity, and business overhead, and the inevitable reward halvings can put a damper on many a mining operation, considering it means their earnings will be cut in half. Although halvings can be anticipated, the end result is usual a big loss. In addition, mining equipment and effort involved has become too expensive and complex for most private individuals to handle. Therefore, bitcoin trading is the less risky and ultimately more lucrative option.

What is bitcoin trading?

Bitcoin trading can be profitable both for financial experts as well as absolute newcomers. The great thing about trading bitcoin is that the currency is not dependent on the economic well-being of a certain country or region and trading goes on around the clock. Bitcoin is also extremely volatile, with its pricing wildly fluctuating. As with any type of trading, beginners should start slow by investing small amounts of capital while learning the ropes both to protect their assets as well as minimize risk. In addition, each investor should pay close attention to market signals to increase their understanding as well as learn many key bitcoin trading strategies.

Where can I buy bitcoins?

If you're looking to buy and trade bitcoins, the UK bitcoin exchange has many companies that can help you complete this process. Companies on the exchange can advise you on many bitcoin trading related issues, offer you a trustworthy exchange platform, a fast an efficient way to buy and trade bitcoins, as well as the option to pay in various currencies using a variety of payment methods.

The Great Bitcoin Scam

Bitcoins


At the outset, let me clarify that Bitcoin itself is not a scam, but how Bitcoin is being sold is a scam. Moreabout that below.

To start out, it is important to understand what Bitcoin really is. It would be easy to bore you with a discussion of the technology, about peer-to-peer servers and sophisticated algorithms, but that is not what you need to know.

What you need to know about Bitcoin is that distilled to its technological essence, each Bitcoin is simply a number. That's it: A number. It is simply a series of digits, with each number being assigned to each Bitcoin.

To illustrate, I'll randomly pull a $1 bill from my wallet, which bears No. L88793293J. Assuming some minimallevel of competency by the U.S. Treasury, no other bill bears that number.

The face value of a $1 bill is, of course, just $1 dollar. But two people could privately agree that No.L88793293J is actually worth $5,000.

To illustrate Fred wants to buy Joe's golf clubs, but Fred doesn't want his wife to know -- at least just yet -- that he spent $5,000 for golf clubs. So, Fred and Joe agree that No. L88793293J is worth $5,000 and Fred gives No. L88793293J to Joe. Fred then tells his wife that he bought the clubs for the $1 bill. At some later time, when Fred's wife doesn't care so much, Fred pays $5,000 to Joe for No. L88793293J, and gets the $1 bill back.

The only difference between Bitcoin No. ABC123 and $1 Bill No. L88793293J is that at the end of the day, the $1 bill physically exists and has a face value that is worth something, i.e., Fred could take the $1 bill and buy something off the $1 menu at McDonalds.

By contrast, Bitcoin has no intrinsic value -- it is just a number. The number may have an agreed value between two parties, but the number itself has no value. Consider a bank account number, such as Wells Fargo Account No. 456789. The depositor and Wells Fargo essentially agree that the account designated by No. 456789 has the value of what the depositor puts into it, less what the depositor takes out. But the number itself, No. 456789 has no value. The same situation occurs with credit card transactions, whereby the credit card processing company assigns are unique value to each transaction, but the number itself has no value.

Let's now talk about uniqueness. Bitcoin does have some value because there are only a finite number of Bitcoins available, because the algorithm that is used limits Bitcoin to a particular number of units, of which there should only be somewhere in the neighborhood of 21 million that fit the algorithm.

Uniqueness certainly has value. Because there is only one Hope Diamond, it is estimated to have a value in the neighborhood of $350 million. Because there are only 100 of that 24¢ stamp with the upside down airplane, they are estimated to be worth about $1 million each. Ditto for rare coins, original Picasso paintings, etc.

But here is where the fundamental flaw in Bitcoin's value lies: It is simply a number, and numbers are infinite  -- there will never be a shortage of numbers. Even if you are the world's greatest mathematician and think that you found the largest number ever, there is always that number plus one, plus two, etc.

So, Bitcoin may be limited to 21 million numbers, but that doesn't mean that somebody else can't come up with a similar algorithm and thereby create their own unique set of numbers, i.e., their own cybercurrency.

For example, let's say that somebody creates a cybercurrency that is based on known prime numbers. There are about 50 million of those, so another 50 million cybercurrency numbers could be created. Indeed, the recent boom in Bitcoin has triggered numerous companies offering their own cybercurrencies, and the amount of such numbers that they can generate is limited only by the ability of their mathematicians to create the necessary algorithms, which of course is similarly infinite.

According to that tome of all knowledge known as Wikipedia, as of November 27, 2017, there were 1,324 cybercurrencies in use. Just multiple each cybercurrency by the number of units they each support, and you get a pretty big number. And that is just the presently existing cybercurrencies, recalling that all it really takes is a sharp mathematician to come up for an algorithm for a new one.

And that brings us back to the main point: Cybercurrency units are simply numbers, and there is not a finite supply of numbers. Rather, the numbers available are infinite. This further means that the supply of cybercurrency units is likewise infinite. This has profound implications for pricing.

The true value of any widget is determined by the aggregate street price of the item, i.e., the sum total of what all units could be purchased for today, divided by the number of additional units which are available for sale. This is where uniqueness comes into play. There is only one Hope Diamond, which means that you take its estimated value of $350 million and divide by one, yielding $350 million. Collectively, those 24¢ stamps with the upside-down airplane are worth $100 million, but there are 100 of them, so they are worth about $1 million each. Or think of it simply in common-sense terms: The more there are of something, the less valuable each one is; if the market is flooded with something, they each have little value. Consumers see this every day at the gas pump, as the price of fuel varies primarily based upon available oil supplies.

Herein lies the problem with cybercurrency, which is that there are an infinite number of cybercurrency units available. Divide anything by infinity, and you get a number that is almost zero -- not quite zero -- but as close as you can get to it as possible. This is true even if we assign a current aggregate value of all the existing cybercurrency units at $500 billion. Because it is not quite zero, we can assign it a value of 1¢, not because it is necessarily worth 1¢, but simply because that is the smallest unit by which we can designate value in our currency.

Actually, it is some number larger than zero, and thus 1¢, mainly because the Bitcoin folks have put in a lot of effort to keep each number unique and assignable to a given owner, and there are some merchants who will accept Bitcoin as if it were a government-issued currency. But how much does that really add, and how unique are those features as other cybercurrencies take hold? Suffice it to say that the answer is much closer to 1¢ than $15,000 per unit.

This now brings us to the economic law of supply and demand, by which value is determined by what a willing seller will let a unit go for, and what a willing buyer will pay for that unit, at a particular moment in time.

Take the 24¢ stamp with the upside-down airplane as an example. Presumably, the U.S. Postal Service would honor the stamp only for 24¢, which is its face value. Otherwise, the stamp creates no other value. But collectors of stamps and other valuables would offer $1 million or more for such a stamp, due to its rarity, and their belief that the value of the stamp will increase over time.

This now brings us to the topic of tulip bulbs. Tulip bulbs have no intrinsic value, other than that they can produce a pretty tulip flower. Yet, beginning in 1636, the price of tulip bulbs in Holland began to skyrocket, as buyers started believing that -- with demand driven by exports to the apparently then tulip bulb hungry French -- the price of tulip bulbs would keep appreciating. They were right. Eventually, the price of a single tulip bulb hit many multiples of the average Dutchman's average wages, and reportedly 12 valuable acres of land were traded for one particular tulip bulb. Individual tulip bulbs were traded for many times each day, with the price increasing with each trade. Then, one day in February of the following year, 1637, the price of tulip bulbs quit going up, and by May 1, the price for tulip bulbs had fallen back to their original value. Thus, was tulip mania the first recorded bubble.

Many centuries later, more specifically in November, 2013, the President of the Dutch Central Bank, Nout Wellink, reflected on the tulip bulb bubble with the following: "At least then you got a tulip, now you get nothing." He was referring to Bitcoin.

But Wellink wasn't exactly right, since with Bitcoin you get a unique number. What that unique number is worth,as discussed above, is something pretty close to zero, which makes Wellink's statement much closer to the truth.

All of which means that the value of Bitcoin, and any other cybercurrency, is established by agreement of the willing sellers and willing buyers as to what point they would be willing to let go of or buy up Bitcoins as the case may be. This means that an investment in Bitcoins is purely speculative -- it is utterly no different than investing in gold, social-media stocks, or tulip bulbs. So long as the number of buyers outnumbers the sellers, the price will go up, but when the sellers outnumber the buyers the price will go down.

You'd think that folks would be able to spot bubbles by now, since we have three in the last 20 years, being the Dot.com (or, maybe more accurately, Dot.con) bubble of the late 1990s, and of course the housing bubble that ended in the crash of 2007, and then the instant Bitcoin bubble. These bubbles illustrate that they occur not because of sophisticated Wall Street traders looking a business fundamentals, but because the less sophisticated investors who start taking money out of their nice, safe FDIC-insured deposit accounts and money-market IRAs, and start trying to shoot-the-moon with investments that they barely understand. Yet, they see other folks making money overnight and want to do so too. Ask about anybody what the key to successful investing is, and they'll repeat the old mantra "Buy low and sell high". The problem with people chasing investments which are already hot is that they will end up buying high and selling low.

All of this brings us to the scam element of Bitcoin. Again, as I stated at the start of this article, Bitcoin itself is not a scam. Now let me tell you what is. The scam in Bitcoin is in talking average man-on-the-street investors into investing in Bitcoin by intentionally obfuscating what it really is, just a number, into some super-sophisticated investment by throwing out the technical verbiage that surrounds cybercurrencies, such as Blockchain technology and peer-to-peer servers. These technologies actually accomplish only one critical thing, which is that they keep particular numbers peculiar to Bitcoin, but they sure sound like Star Trek level stuff. Yet, to those not familiar with these technologies, it makes Bitcoin sounds like it has a lot more worth than it really does.

To push Bitcoin, there are now a lot of internet gurus who claim to have inside knowledge on the ever-imminent rise of the cybercurrency, very similar to how such gurus appeared so that the Iraqi Dinar Scam (which is very similar, although Dinars at least exist in paper) was able to take off. There are also Bitcoin sellers who spin a load of bull so that they can sell Bitcoins to the unsophisticated investors who can't seem to bring themselves to confront the question that "if something is anywhere as valuable as they say, then why are they selling it?"

The answer is that those who trade in anything make their money on their commissions for selling. It doesn't matter what they are selling, so long as they can make a commission on it. The more trading, the more in commissions. Investments that are perceived as "hot" will generate a lot of trading, and so traders will naturally flock to those investments and try to gin up further interest among investors who heretofore had no interest in that investment at all.

Sure enough, getting away from the wealthy folks who have the spare cash to speculate in stuff, we're now seeing pooled funds set up just so that the average mom-and-pop investors who are simply trying to set some money back for retirement, can throw their bucks in too. What these folks don't realize is that they might as well just take their money to the nearest casino and drop it all on red for a single spin of the roulette wheel. They'll either win or lose, just as Bitcoin is either going to go up or down.

And, at least the casino will pay if you win. I get the idea that some of these "Bitcoin funds" actually own no, or very few, Bitcoins, but are simply the next wave of Ponzi schemes.

I got into a discussion about Bitcoin with retired financial advisor Charles Padua, who expressed concern that so many small investors seemed to be falling for Bitcoin. His take was that smaller investors should be in carefully asset-allocated portfolios so as to spread and minimize their risk, and if -- and this is a big if -- somebody determined to invest in any speculative investment, such as Bitcoin, they should limit their portfolio exposure to no more than 2%. But, he says, better not to invest in purely speculative investments at all.

This takes up back to the fundamental rule of investing, which is simply to buy low and sell high. Bitcoin is already high, and astronomically high compared to its true value. Folks who buy into Bitcoin now are quite likely to be buying high and will end up selling low. There is also an old investment adage to the effect that "the quickest way to lose money is to invest in something which is already hot." The idea there is that the folks who are going to profit have already made their money investing, and now are just looking for suckers to unload their investment on. Bitcoin is certainly hot; in fact, it's now the hottest thing going. That by itself should raise a bright red flag for investors.

Will Bitcoin fall? Maybe not today, tomorrow, or next week, but eventually it will fall as the novelty wears off and folks figure out that they are really just buying a number, and the number of buyers diminish.

Will Bitcoin go away entirely? Probably not, because Bitcoin still can serve some usefulness as a unit of exchange, to the extent that it can convince merchants to accept it as currency. The caveat here is that when a bubble finally bursts, the object of the bubble usually falls into deep disrepute.

By then the scammers who prey on the little investors will have moved on to the next "big thing". It is all a never ending cycle, limited only by the number of available suckers.

And that is a big, big number.

The Case for Bitcoin for Institutional Investors

In this work we assume the institutional investor role and analyze a possible investment in bitcoin (BTC). We document several salient features of BTC employing monthly returns over the period from August 2010 to October 2017. First, it provides unique diversification benefits for traditional institutional portfolios. This diversification benefit appears to be stable over our sample period. Second, bitcoin is very volatile, indeed, but the historical return to risk ratio appears attractive with a Sharpe Ratio of 1.176. Finally, using standard portfolio optimization tools we find that the optimal allocation to BTC is 1.3% over the sample we examined. We provide controversial evidence that institutional investors are under allocated to BTC.

Evolution of Bitcoin

Bitcoin volatility is known to be high, as is shown by comparing Bitcoin volatility to several currencies and to assets like stock, gold etc. This work attempts to extend this work by comparing Bitcoin volatility to volatility of currencies of least developed countries and other cryptocurrencies. Exchange rate and return data drawn from Bloomberg and covering March 2014 to March 2017 was analysed. It was found that Bitcoin volatility is still considerably higher than volatilities of currencies of least developed countries. Only five currencies were more volatile for more than 10% of the time spa

Beyond Bitcoin and Cash

The aim of this paper is to offer a theoretical primer in order to analyse the demand of a central bank digital currency (CBDC). Using a financial portfolio approach and assuming that individual preferences and policy votes are consistent, we identify the drivers of the political consensus in favour or against such as new currency. Given three different properties of a currency – where the first two are the standard functions of medium of exchange and store of value and the third one is the less explored function of store of information – and three different existing moneys – paper currency, banking currency and cryptocurrency – if the individuals are rational but at the same time can be affected by behavioural biases – loss aversion - three different groups of individuals – respectively lovers, neutrals and haters – emerge respect to the CBDC option. Given the alternative opportunity costs of the different currencies, the CBDC issuing is more likely to occur the more the individuals likes to use a legal tender, and/or are indifferent respect to anonymity; at the same time, the probability of the CBDC introduction increases if a return can be paid on it, and/or its implementation can guarantee at least the counterparty anonymity.

Holding Bitcoin Longer



Summary

We investigate whether Bitcoin can hedge and diversify risk against the Euro STOXX Index, Nikkei, Shanghai A-Share, S&P 500 and the TSX Index, and the dynamics of these abilities over different sample periods and data frequencies. Pairwise GARCH process was used for daily, weekly, and monthly return data. We find that Bitcoin is an effective strong hedge for the Euro STOXX Index, Shanghai A-Share, S&P 500 and TSX, and a diversifier for Nikkei under monthly data frequency. These hedging abilities are less significant for weekly and daily frequency. Moreover, the dramatic Bitcoin price increases in 2017 are pivotal in determining its hedging abilities against the Shanghai A-Share, Euro and TSX indices.

1. Introduction

Bitcoin has grown in both price and popularity since its introduction in 2009. On any given day, changes in Bitcoin can headline both finance and technology news. Since its introduction to the world in 2009, prices have remained under $1500.00 USD to the end of 2016. However, the buying frenzy of 2017 lead Bitcoin price to rise to over $18,000.00 USD exhibiting major volatility on its way up (Figure 1). One week after the Chicago Board of Exchange launched its Bitcoin future contract, CME, the world's largest futures exchange, is about to launch its own Bitcoin futures contract. William Dudley, the President and CEO of Federal Reserve Bank of New York is exploring the idea of creating its own digital currency. While the actual reasons for this price boom is up for debate, one common explanation known as the “Satoshi Cycle” suggests that there is a high correlation between Google searches for “Bitcoin” and the actual prices of Bitcoin (Figure 2). Figure 3 provides insight on the positive relationship between Bitcoin’s price and the number of trades occurring that signifies growing market interest.

With Bitcoin’s increased popularity, understanding how its prices are correlated with other financial assets is of interest to investors, regulators and policy makers. Is Bitcoin a valuable asset to add to the portfolio? We will investigate how Bitcoin can be used in risk management against certain equity markets. Specifically, we follow Baur and Lucey’s (2010) research witch demonstrates that an asset exhibits strong hedging features when it is negatively correlated to another asset, and exhibits diversifying features when it is positively correlated with another asset. Dyhrberg (2016a) shows that Bitcoin is uncorrelated with assets in the FTSE Index, but it is positively correlated with the dollar-euro and dollar-sterling exchange rates. Bouri et al. (2017) report that Bitcoin’s daily returns are negatively correlated to the Japanese and Asia Pacific stocks indices, but the correlations fade for weekly data. Both of these studies are based on 2010 to 2015 data. No study, to our knowledge, has investigated how the dramatic price increases in 2017 impact the hedging abilities of Bitcoin. We fill this gap by providing an up-todate analysis of Bitcoin’s hedging ability against several major equity markets. To capture the impact of 2017 price surges on the hedging abilities, we analyze the correlations with and without 2017 data.

Bitcoin daily price data from October 2010 (the earliest data available) to October 2017 was used to investigate how Bitcoin can hedge or diversify risk against the Euro STOXX Index, Nikkei, Shanghai A-Share, S&P 500 and TSX Index conditional on daily, weekly and monthly data frequencies. Firstly, we find that Bitcoin’s daily price exhibits risk-mitigating abilities for the Shanghai A-Share index; Secondly, we find Bitcoin is a strong hedge against the Euro-Index, S&P 500, Shanghai A-Share and TSX Index for monthly data through negative relationships in returns, and is a diversifier for Nikkei through a positive relationship in returns. These findings suggest that Bitcoin is more effective at hedging and diversifying against equity markets for monthly frequency than for daily and weekly data frequencies.

We employ sub-period testing with data from 2010-2016. The 2010-2016 daily result indicates that the Shanghai A-Share is negatively correlated to Bitcoin returns similar to the full sample result, therefore Bitcoin’s daily hedging ability against Shanghai A-Share does not depend on the price change in 2017. Similarly, Bitcoin’s monthly returns have a negative correlation with S&P 500 returns and a positive correlation with Nikkei returns, similar to the full sample results. However, the monthly sub-period testing for 2010-2016 no longer shows a significant negative relationship for the Euro-Index, Shanghai A-Share, or TSX Index to Bitcoin returns. This indicates that structural changes in Bitcoin’s 2017 price are pivotal in determining Bitcoin’s hedging and diversification abilities for the Euro STOXX Index, Shanghai A-Share, and TSX Index.

We contribute to the extant literature by showing that Bitcoin provides effective risk management functions under monthly data frequencies. This is the first study analyzing Bitcoin’s hedging ability using monthly data and the first analysis of the TSE and Euro index. Secondly, our sample covers a longer time period, which enables us to find that Bitcoin’s risk management abilities are more significant than the previous literature indicates. Thirdly, we provide the first study highlighting how sensitive these hedging and diversification abilities are in relation to the big price changes of 2017.
