- ДокументAssessing the probability of bankruptcy when investing in cryptocurrency(Суми: ТОВ «Консалтингова видавнича компанія «Перспективи бізнесу», 2022-09-14) Serhii Kozlovskyi; aroslav Petrunenko; Hennadii Mazur; Vira Butenko; Natalya IvanyutaThe cryptocurrency market is not regulated, people and companies wishing to invest in cryptocurrency do not have the same protection as when investing in other assets. In the absence of information and regulatory laws, investors should decide if cryptocurrencies make sense for their financial goals and what kind of investment strategy to choose not to go bankrupt. The aim of the study is to determine the probability of “tail events” and to assess in this way the probability of bankruptcy when investing in cryptocurrency using the Monte Carlo method. The analysis is carried out on the period from September 1, 2014 up to July 1, 2022. Despite the fact that today there are more than 10,000 types of cryptocurrencies, Bitcoin was chosen to assess the probability of bankruptcy. The reason is that Bitcoin is the world’s first decentralized cryptocurrency and its data is stored in a long-term history, which allows testing a long-term investment strategy. Besides, Bitcoin has not gone through a period of persistent inflation that makes the result of testing a short-term investment strategy more reliable. To date, there are around 25 million Bitcoin holders, representing 42.2% of the crypto market. Almost all cryptocurrencies have been proven to follow Bitcoin. The probability of bankruptcy for a short-term cryptocurrency investment strategy is about 17%-23%. For a long-term cryptocurrency investment strategy, the probability of bankruptcy fluctuates from 13% to 16%. Contrary to popular belief, investors looking to avoid bankruptcy should prefer a long-term strategy. The best way for cryptocurrency investors to protect themselves from bankruptcy is to alternate long and short investment periods.

- ДокументDETERMINATION OF THE RISK-FREE RATE OF RETURN ON AN INVESTMENT EFFICIENCY BASED ON THE FRACTAL MARKETS HYPOTHESIS(Варшава: УНІВЕРСИТЕТ WSB, 2020) Andrii KozlovskyI; Daria Bilenko; Serhii Kozlovskyi; Ruslan Lavrov; Oleh Skydan; Natalya IvanyutaIn determining the economic efficiency of an investment project, the rationale and choice of the discount rate is the most difficult step. The methods of investment assessment are built on the rate of return used to discount future cash flows back to their present value. To increase the accuracy of calculations and reduce the subjective assessments of experts, statistical methods are used. The market process is known to be stochastic. Therefore, investors know that the application of statistical methods is not practical, and thus prefer to use their ntuition and professional experience. The alternative group of methods such as the Fractal Markets Hypothesis is not widely used because it is difficult to carry out calculations according to the proposed formulas in practice. In this paper, the aim is to propose a method for determining the risk-free rate of return on an investment project based on the Fractal Markets Hypothesis for identifying long-term dependence and assessing the contribution to the total result of changes in inflation. The objective of the study is the determination of the risk-free rate of return on an investment project. The real risk-free rate is calculated as the existing inflation rate. The result of this paper is the definition of inflation boundaries for Poland, Ukraine and Russia, which may be used for determining the risk-free rate of return on an investment project.
