This work carries out a brief investigation of cryptocurrencies mining market in Brazil and to analyze the economic viability of the investment in a Bitcoin mining farm in Brazil. The study was carried out in three stages, where deterministic analyzes were based on possible scenarios, observation of the sensitivity of the investment relative to the main variables of the problem and finally the use of stochastic methods to estimate the investment risk under uncertainty. The study points to the cost of electricity as the most significant, followed by investment in mining equipment and suggests that the operation be established in countries with lower electricity costs, lower climate and lower import and income tax rates.
