One way to invest in Bitcoin that has a positive effect on renewable energy is to encourage mining operations near wind or solar sites. This provides a customer for power that might otherwise need to be transmitted or stored, saving money as well as carbon. Currently, projects are under development, but the issue of overgenerated wind continues to exist. By harnessing the overgenerated wind for Bitcoin mining, Wyoming has the opportunity to redistribute the global hashrate, incentivize Bitcoin miners to move their operations to Wyoming, and stimulate job growth as a result.
Rochester, NY. In responding to these pressures and events, some miners are providing services and innovations that may help the viability of clean energy infrastructures for energy providers and beyond, including the data and computing industry. The paper finds that if Bitcoin loses legitimacy as a store of value, then it may result in lost opportunities to accelerate sustainable energy infrastructures and markets.
Parvez 1 November Bibcode : ITAS The main problem facing the PV power plants deployment is the intermittency which leads to instability of the grid. Renewable and Sustainable Energy Reviews. Windfarms can hedge electricity price risk by investing in Bitcoin mining. The enormous energy demand from Bitcoin mining is a considerable burden to achieve the climate agenda and the energy cost is the major operation cost. On the other side, with high penetration of renewable resources, the grid makes curtailment for reliability reasons, which reduces both economic and environment benefits from renewable energy.
Deploying the Bitcoin mining machines at renewable power plants can mitigate both problems.

One of the most important factors was the mistrust of market participants in the world financial system Belomyttseva, We will try to analyze the prospects and risks of the cryptocurrency development in the financial markets and assess the possibilities of using blockchain technology in other areas of activity.
Bitcoin is a currency, a digital unit of value that people use to exchange goods, services, or exchange for other currencies, the exchange rate of which tends to fluctuate significantly compared to traditional fiduciary fiat money. The key differences between bitcoin and fiat money are decentralization; unaffected inflation; anonymity to a certain extent ; transparency; impossibility to cancel transactions.
Derivative cryptocurrencies usually differ from each other by the cryptographic algorithm, which is the basis of the emission. Electronic money is usually understood as the value in monetary terms, which is stored on an electronic medium, issued by the issuer when receiving money from other persons in an amount not less than the emitted money value, and is accepted as a means of payment by persons other than the issuer.
The common between Bitcoin and electronic money is their information nature and digital format. Virtual currency is also different from electronic money, which acts as a surrogate of payment means. In formal terms, it appears as: a means of exchange; an estimated monetary unit; a means of value storage, but it does not have payment properties in any jurisdiction.
This definition differs from that proposed by the ECB, which defined virtual currency as a type of unregulated digital money. It is issued and controlled by its developers, and is used and accepted by members of a particular virtual community European Central Bank, Later, the use of the term "money" in relation to virtual currencies was found to be incorrect. Virtual currency is already defined as "a digital image of value which is not issued by a central bank, credit institution or electronic money institution, and which, in some circumstances, can be used as an alternative to money" European Central Bank, In case of cryptocurrency, the formalization of money in various forms, as a participant in the exchange, reaches the highest point of abstraction Kosogayev, The combination of blockchain technologies and cryptocurrency provides the transfer of information that does not need centralized administration.
The advantage of blockchain technology is its openness and reliability. The distributed nature of the database makes it resistant to hacker attacks and tampering attempts. Information in the database is very difficult to change, delete or fake. However, all the data can be easily checked and tracked. The technology allows seeing the entire chain of any asset transactions, which minimizes the risks of fraud or errors in accounting and auditing.
Further, blockchain-based solutions spread to other components of the financial market. The use of this technology will increase financial inclusiveness at low maintenance costs. Processes with trends or with variable dispersion are typical for the unstable rapidly growing concept of cryptocurrencies.
One of the problems in determining the model structure is the establishment of nonlinearities in the process under investigation and their type. The dynamics of cryptocurrency is a nonlinear phenomenon. There are various ways to set the prediction problem, but in any case it affects the following components of the process: the deterministic trend, the random trend, short-term changes, seasonal effects, the rate of the process change, dispersion or standard deviation as a measure of process dispersion.
According to the process components that need to be predicted, the problem of mathematical model development is posed. Let us consider some possibilities to create a mathematical description of compound processes of different nature. If we describe a deterministic trend with a polynomial from time of arbitrary order, then the trend forecast determination is reduced to substituting the desired time value k in this equation and applying unconditional mathematical expectation:.
Cryptocurrencies based on blockchain technology have already become a significant element in the modern financial market and a significant investment object. At present, we can observe an increase in the diversity of cryptocurrencies represented in the information environment Figure 1. Bitcoin is still the leading currency, which determines the trend not only for the use of cryptocurrency, but also for the whole spectrum of the blockchain technology development.
Certainly, it makes sense that most of the new cryptocurrency will develop on the basis of Bitcoin and as its derivation. At the same time, there is a tendency when the number of transactions increases in the currency that allows quick withdrawal of funds Table 1. Here is a constant conjugation with the increasing use of cryptocurrency. Table 1 Daily number of transactions with cryptocurrencies. Dynamics shows that the concentration of the volume of a particular cryptocurrency is not much different from the concentration of other resources in the society.
It should be noted that all cryptocurrencies are based on the starting value of Bitcoin. Therefore, it is Bitcoin that determines events in the market of cryptocurrencies. Let us analyze and build models for describing Bitcoin indicators. Table 2 shows the dynamics of changes in the exchange rate of Bitcoin in Table 2 Changes in the exchange rate of Bitcoin cryptocurrency for The most "unprofitable" was September, during which the cryptocurrency value decreased by One of the most common methods for predicting the dynamics of market indicators is the trend model.
The Microsoft Excel package allows automating the development of trend models and their analysis. To assess the model adequacy, the determination coefficient can be used referred to as R2. To select the best trend model, several different options should be calculated. For the Bitcoin exchange rate in , 6 different models were developed and their determination coefficients were calculated Table 3. Table 3 Determination coefficients of Bitcoin trend models for Table 3 shows that the third-degree polynomial model and the exponential model best correspond to observations.
For both of them, the determination coefficient is close to the boundaries of the confidence interval 0. Figure 2 shows the dynamics of the Bitcoin exchange rate and the trend lines, which correspond to the third-degree polynomial model and the exponential model. As you can see, both models confidently predict the growth of Bitcoin's value in the future. At the same time, it is possible that the value of Bitcoin will decrease and the level of availability of other currencies will increase.
Cryptocurrencies have recently demonstrated impressive growth dynamics, but this is due to the rapidly growing public interest in cryptocurrencies, which provokes demand in the market, while limiting the supply. The peak of excessive demand has probably already been achieved or will be achieved at the nearest moment. Next, we should expect the stabilization of the dynamics. Therefore, after the inevitable decrease in the exchange rate, their volatility, perhaps, will fall.
Drawing parallels between the direction of the market price chart and various publications about Bitcoin in the media allows concluding that the demand for cryptocurrency is subject to strong fluctuations and is largely due to the market's expectation of further value Uperyaka, Exchange rate determination depends only on the network effect, and the ratio of supply and demand, while the limitation of the emissions volume will result in the deflation of the currency value in the presence of the network effect Trubnikova, In case of transactions with cryptocurrency, their number will increase.
According to various estimates, no more than 2. Currently, there is a tendency of increasing the share of non-cash payments Genkin, This is primarily due to the fact that cryptocurrencies often rely on small payments, which will be much cheaper due to distributed processing.
Hence, it can be concluded that the change in the number of transactions will be affected by the transfer commission factor. The use of blockchain opens up new areas for the application of this technology. These include, first of all, trading platforms, corporate governance systems, property rights databases, networks and payment systems for retail e-commerce, public procurement systems, budget management and fiscal functions implementation, traditional or parametric insurance.
Undoubtedly, blockchain technologies are used primarily in standardized trade. Trading stocks or other financial instruments determines the trend in this direction. The use of blockchain technology is not limited to the transactional business of financial institutions, that is, payments, settlements and related services Sherman, This crypto technology can be used in many business processes.
It is possible to create corporate distributed databases using blockchain, which will take into account the needs of each individual company and organize interaction between all participants providing necessary level of security and confidentiality Motkova,
