Based on this, it can be claimed that by using two or more combined methods, more levels and dimensions of a problematic situation can be investigated and the results are definitely more reliable.  The main goal of this research is to solve the problems of electricity shortage caused by cryptocurrency mining in Iran by combining three methods: Strategic choice Approach(SCA), Strategic Option Development and Analysis(SODA), Critical Systems Heuristics(CSH), while examining more detailed levels and dimensions of the problem, solutions or decisions should be adopted to be more reliable and more effective.The combination method is such that SCA is placed as the basis and platform of the research method, In the fourth and eighth steps of sca, soda and csh methods have been used, respectively. The results of this research show wider levels and dimensions of the problems and problems of electricity shortages caused by cryptocurrency mining and lead to the important point that the advantages and benefits of digital currencies should not be ignored due to electricity shortages.
