Some Harvard Economics professors say the current high valuation of bitcoin—the founding coin of the international virtual currency boom—is unsustainable and will eventually drop, thanks in part to government regulation. In the early years, bitcoin was worth comparatively little, ranging in value from five to 20 dollars. Economics professor Kenneth S. But that anonymity may soon end—Rogoff said he thinks governments will probably want to identify bitcoin users in the future. He pointed to China as an example of a nation that has already banned bitcoin exchanges.

Bitcoin in the economics and finance literature: a survey
The first commercial transaction with the first cryptocurrency in marked the start of a revolution in transactions. Blockchain and cryptocurrencies will dramatically transform how we do transactions, just as the Internet revolutionized how we communicate. Currently, more than 2, cryptocurrencies are quoted on the market, and many more are being launched in initial coin offerings for use as an exchange method in a specific business ecosystem or as rights to assets or liabilities.
As an emerging fintech, cryptocurrencies open up many opportunities, but they also pose significant challenges and limitations. This paper analyzes the key factors for the successful development of a cryptocurrency from a consumer-behavior perspective. Surprisingly, risk was not a significant factor. This could be because most of the respondents considered operating with cryptocurrencies to be risky; the lack of variability in their responses to the questions about perceived risk would explain this lack of explanatory power.
However, willingness to manage cryptocurrency risk could be a precondition for adoption. The performance expectancy for a given cryptocurrency was the most important factor for its success. The research was conducted in Spain with college-educated adults with basic knowledge of the Internet. Cryptocurrencies are based on blockchain but are not the only possible application. There is a dangerous relationship between blockchain and cryptocurrencies Carson et al. Although blockchain is expected to dramatically impact and have applications in most economic sectors and activities, at present cryptocurrencies remain more important.
The World Bank defines a non-fiat digital currency as a digital currency that is not backed by any underlying asset, has zero intrinsic value, and does not represent a liability on any institution Natarajan et al. Digital currencies based on blockchain technology, which employs cryptographic techniques, are considered cryptocurrencies. The U. Federal Reserve considers the current payment system to be slow, insecure, inefficient, uncollaborative, and non-global Federal Reserve System, Cryptocurrencies are seen as a potential instrument for solving all these problems Deloitte, From the start of this revolution with the launch of bitcoin, the first cryptocurrency, the business and economic worlds have sought to adapt and integrate the new financial technology into their activities.
In , the first retail purchase was made with Bitcoins. Laszlo Hanyecz paid 10, bitcoins for two pizzas Bort, Nor does that number include all cryptocurrencies, just the ones quoted on the market to be bought and sold.
Today, any business can create its own cryptocurrency using blockchain technology and determine its use through an initial coin offering ICO. The new cryptocurrency can be used as an internal business ecosystem payment method to grant access to the products or services the ecosystem offers; it can represent a right to an asset or liability; or it can be used as a speculative cryptocurrency whose value is based on market expectations.
The range is very wide and will only grow wider in the coming years. Illegal activities with cryptocurrencies are a fact, especially with bitcoin, the first and most frequently used Turner et al. For instance, cryptocurrencies have been used for tax evasion, money laundering, contraband transactions, extortion, and the theft of bitcoins themselves Bloomberg, Another drawback is that cryptocurrencies are not an easy technology to use; operating with bitcoins is a major challenge for many users Krombholz et al.
One qualitative study found that non-users of bitcoin felt incapable of using it Gao et al. In addition to the lack of technological know-how, financial literacy can also constrain the development of cryptocurrencies. Given this low level of financial literacy, explaining financial concepts related to cryptocurrencies could be difficult CCN, Social perception will also be key to cryptocurrency development.
In short, cryptocurrencies open up many opportunities, such as fast, efficient, traceable, and secure transactions, but also have drawbacks, such as their inherent risk, the technological and financial difficulty of using them, and the uncertain social perception of owning them. The complexity and consequences of the blockchain and cryptocurrency revolution make it imperative to analyze its impacts and challenges from an interdisciplinary perspective.
Although some research has been done on bitcoin, as the most widely used and important cryptocurrency today Holub and Johnson, , the literature on cryptocurrencies in general is scarce, mainly due to their novelty. This paper focuses on the critical factors that any cryptocurrency must consider to succeed in the emerging and chaotic cryptocurrency market. Specifically, it uses technology acceptance models to analyze the influence of perceived risk, performance expectancy, facilitating conditions, effort expectancy, social influence, and financial literacy on the intention to use cryptocurrencies.
Determining the key factors for customer acceptance of cryptocurrencies would let current and future market players focus on the most important features a cryptocurrency should have. The research was conducted in Spain with a sample of college-educated adults with basic knowledge of the Internet. UTAUT models define a direct and positive influence of performance expectancy, social norm, and facilitating conditions on the intention to use a technology.
Performance expectancy is defined as the degree to which a person considers that using a specific technology would be useful to enhance his or her performance.
Effort expectancy is defined as the degree of ease associated with the use of a specific technology. Social influence is defined as the degree to which a person perceives that others believe that he or she should use a specific technology. Facilitating conditions are defined as the degree to which a person believes that he or she has the necessary organizational and technical infrastructure to use a specific technology Venkatesh et al.
Several studies have looked at the influence of these variables on the acceptance of financial technologies, or fintech, but no consensus has been reached regarding their influence on the intention to use them. On the contrary, important differences have been found depending on the type of technology and target segment. For instance, Moon and Hwang show that effort expectancy and social influence positively affect the intention to use crowdfunding, but find no evidence that performance expectancy and facilitating conditions do.
In contrast, Kim et al. Makanyeza and Mutambayashata show that while performance expectancy and effort expectancy positively influence the behavioral intention to adopt plastic money, social influence and facilitating conditions do not significantly affect it.
Khan et al. Several studies have likewise looked at the adoption of mobile banking m-banking. For instance, Farah et al. Warsame and Ireri show that for some consumer segments based on age, gender, and religion performance expectancy and effort expectancy significantly influence the intention to use mobile microfinance services, while for others these factors do not affect acceptance.
These authors further demonstrate that social influence affects the intention to use mobile microfinance services in all segments. In their study of mobile payment adoption specifically by the base-of the-pyramid BoP segment, i. Focusing on m-banking in Bangladesh, Mahfuz et al. Additionally, they find that while performance expectancy and facilitating conditions do not significantly affect the intention to use this technology, facilitating conditions do affect actual use of it.
Similarly, in a study conducted in Karnataka, in rural India, Kishore and Sequeira show that performance expectancy, effort expectancy, and social influence have significant explanatory power with regard to the adoption of m-banking. As for the literature specifically on cryptocurrencies and bitcoin, Mendoza-Tello et al. According to another study on cryptocurrency adoption based on the TPB, subjective norms social influence and perceived behavioral control how easy or difficult it is to use cryptocurrencies are significant Schaupp and Festa, : people who perceive cryptocurrencies as easy to use and people receiving a positive social influence regarding their use are more likely to use them.
Bitcoin has also been analyzed as a cryptocurrency. In an acceptance study in China, Shahzad et al. Based on these findings regarding the acceptance of financial technologies, the following hypotheses are proposed:. Performance expectancy regarding the use of cryptocurrencies positively influences the intention to use them.
Effort expectancy regarding the use of cryptocurrencies positively influences the intention to use them. Social influence regarding the use of cryptocurrencies positively influences the intention to use them. Facilitating conditions for the use of cryptocurrencies positively influences the intention to use them.
Perceived risk has been considered a determinant of consumer behavior in the context of purchase intention e. Several recent studies analyze the influence of perceived risk on the intention to use financial technologies with contradictory results.
In their study of the intention to use online banking, Khan et al. Kishore and Sequeira show that perceived risk has significant moderate explanatory power with regard to the adoption of m-banking in rural areas. Shaikh et al.
Farah et al. Likewise, Moon and Hwang find no evidence that perceived risk negatively affects the intention to use crowdfunding. With regard to the literature on cryptocurrencies in particular, Mendoza-Tello et al. Based on the understanding of cryptocurrencies as an emerging fintech entailing potential risk, the following hypothesis is proposed:. The perceived risk of using cryptocurrencies negatively influences the intention to use them. Stolper and Walter define financial knowledge as the degree of knowledge a person has about key financial concepts and their capacity to apply that knowledge to their financial decision-making.
Several studies demonstrate that financial knowledge is a predictive variable of financial behaviors. Van Rooij et al. Their research includes papers from the United States and other countries. Likewise, Stolper and Walter argue that higher levels of financial knowledge are associated with more saving planning, more saving behavior, more stock market participation, and smarter choices when it comes to the selection of financial products; at the same time, lower levels of financial knowledge are associated with poorer financial decisions, more expensive loans, costly credit card practices, and excessive debt accumulation.
In their literature review, Hastings et al. Stolper and Walter report similar findings, showing that many research papers demonstrate that people with a higher level of financial knowledge are more cautious about their financial decisions.
Lam and Lam demonstrate the important influence of financial knowledge on problems related to online shopping, such as addiction or compulsive shopping behaviors. Given that cryptocurrencies are a technological financial product, and based on the above findings regarding the influence of financial literacy on the use of financial products, the following hypothesis is proposed:.
Financial literacy positively influences the intention to use cryptocurrencies. Figure 1 shows the proposed model for analyzing the intention to use cryptocurrencies. We used a structured and self-administered online survey to sample people over the age of 20, living in Spain, who had a university degree.
We sent invitations to people with this profile without making any distinctions for age, gender, or household income until we achieved the desired sample size and composition to enable reliable research. Due to the online nature of the survey, the sample is limited to people with a basic command of the Internet. As noted in the introduction, because cryptocurrencies are based on blockchain technologies, a minimum level of both technological and financial knowledge is needed to have a basic understanding of how to operate with them.
Consequently, in order to survey people likely to have a reasonable understanding of these technologies, we focused on college-educated adults. This allowed us to ensure that the respondents would have the minimum required knowledge. This decision regarding the sample was based on other studies that justify the choice of a highly educated sample as a means of making suring that respondents have a higher level of financial knowledge in order to ensure that the collected data will fit the research purpose Hastings et al.
The sample consisted of people, over the age of 20, living in Spain and with a university degree and a basic grasp of the Internet. The data were collected between August 1 and September 10, The innovative blockchain-based financial and insurance services emerging today reduce intermediation and transaction costs, but they could also be insecure and risky if used incorrectly.
Cryptocurrencies such as bitcoin are a perfect example of blockchain-based financial innovation, offering inalterable, anonymous, and traceable transactions.

Bitcoin Price Prediction for 2020
This is a very important question and it is always good to have some ideas as to what the price trajectory for Bitcoin will be heading down towards this halving event, and thereafter for the rest of Bitcoin had a very interesting Bitcoin started off this year on a bullish note. Let us look at what these factors are and how they will play a role in the price outlook for Bitcoin in The unheralded Istanbul hardfork is doing some great things within the Bitcoin blockchain itself. A recent report by Coin Metrics, a company that provides analytics of individual blockchain networks and the crypto market, indicates a strong improvement in some of the Bitcoin network metrics. The Ether network is attaining better supply distribution, spreading out Ether hitherto trapped in ICO crowdsales into the hands of new owners.

Investment returns will fluctuate so that investors' shares, when redeemed, may be worth more or less than their original costs. VanEck gives you exposure to Bitcoin without the hassle and risk of private keys and unverified exchanges.
Bitcoin mining is now easier and more profitable as algorithm adjusts after China crackdown
We also speculated that high profits and free entry would cause more miners to enter the market, driving marginal mining profits to zero in the long run. Since then, the price of a bitcoin has declined over 40 percent and both the hash rate and the difficulty level of the bitcoin mining problem, which adjusts automatically to changes in the hash rate, appear to have leveled off. Our most recent calculations suggest the long run may have arrived. The following chart illustrates the path of aggregate bitcoin mining profit since September , using current estimates of chip efficiency and updated electricity price data from the recently published report of the International Energy Agency. The gold line shows our estimate of the aggregate daily profit to bitcoin mining, measured in dollars. The red line shows the difficulty level of the bitcoin mining problem, measured in terms of the expected number of hashes needed to win a new allocation of bitcoins.

It will also examine the accounting and regulatory, and privacy issues surrounding the space. Bitcoin , blockchain , initial coin offerings , ether , exchanges. Originally known for their reputation as havens for criminals and money launderers, cryptocurrencies have come a long way—with regards to both technological advancement and popularity. The technology underlying cryptocurrencies has been said to have powerful applications in various sectors ranging from healthcare to media. With that said, cryptocurrencies remain controversial. It will also examine the outstanding issues surrounding the space, including their evolving accounting and regulatory treatment. Cryptocurrencies are digital assets that use cryptography , an encryption technique, for security.
Smart cities: shaping the society of 2030
The Bitcoin network is burning a large amount of energy for mining. In this paper, we estimate the lower bound for the global mining energy cost for a period of 10 years from to , taking into account changes in energy costs, improvements in hashing technologies and hashing activity. We estimate energy cost for Bitcoin mining using two methods: Brent Crude oil prices as a global standard and regional industrial electricity prices weighted by the share of hashing activity.
The Cost of Bitcoin Mining Has Never Really IncreasedRELATED VIDEO: Bitcoin basics: What is the difficulty target and how does it adjust itself?
The world has known for months that more than half the world's bitcoin miners would be going dark as China cracked down on mining. Now that it's happened , the bitcoin algorithm has adjusted accordingly to make sure miner productivity doesn't continue to fall off a cliff. That adjustment — which took effect early Saturday morning — also means that way more cash is going to the bitcoin miners who remain online. A bitcoin miner runs a program on a computer to try to solve a puzzle before anyone else does.
Blockchain beyond the hype: What is the strategic business value?
How much power does it take to mine a bitcoin? In this assessment we find that an average of , kWh of energy is required to produce one bitcoin. Our method to discover the amount of energy it takes to mine a bitcoin uses data from relevant ASIC models, network size, and current miner profitability. We also calculate the bitcoin production rate and use it to find how much energy the entire network consumes. But this estimate is always changing alongside hash rate size and other factors. Further, find out why we believe hash rate growth may be slowing and is not linear. This model houses a couple hundred TSMC 7nm microprocessor chips.
How Does Bitcoin Mining Work?
Bitcoin provides its users with transaction-processing services which are similar to those of traditional payment systems. We find that this decentralized design protects users from monopoly pricing. Competition among service providers within the platform and free entry imply no entity can profitably affect the level of fees paid by users.
