Behavioral Comparison of Bitcoin Digital Currency with the Adjusted Total Index of Tehran Stock Exchange and Identifying the Effects of Digital Currencies on the Public Security of Semnan Province

Financial markets in general and currencies in particular, each as a living organism has behaviors that are caused by previous similar events and other variables. Identifying probable behaviors shows the inner nature of the behavior and provides the basis for investigating its why. Bitcoin has been one of the biggest digital currencies in the past years and has attracted a lot of capital from all over the world. In addition to this, in Iran, the Tehran Stock Exchange market has seen strong ups and downs, which has led to migration between these two markets in Iran and also in Semnan province. Examining these behaviors in the whole country as well as the positive and negative effects of entering the digital currency markets in the province will lead to more mastery in this area and facilitate future planning. In this study, by comparing the probabilistic behavior of Bitcoin digital currency with the adjusted total index of the country's stock exchange by hidden Markov chains, and by using the TOPSIS technique on the findings of library studies and interviews, we tried to identify the disadvantages and advantages of using digital currencies in Semnan province. The results show that the momentum and fluctuating behavior of the Bitcoin digital currency has higher reliability and less dangerous fluctuations than the overall stock market index, and this is one of the most important reasons for the migration of investors to this market. Currency acquisition, evasion of sanctions, increase in tax and public revenues of the province, facilitating financing of terrorism, lack of codified laws and psychological problems are among the most important advantages and disadvantages identified in this study.
