require the use of multiple graphics processing units (GPUs). Management estimates that the GPUs that are in place will enable Crypto to continue to achieve an effective mining time per block of 480 minutes. Management focus Increasingly, management have spent more and more time trying to find ways to reduce their electricity usage. This problem has been compounded recently given the loadshedding faced by South Africa. Management estimate that in the first half of 2022 they haven't been able to mine profitably for a total of 40 hours due to electricity outages. Management believes that loadshedding will continue for the next five years and this Assume that all installation costs are paid on the 1 September 2022 . Management have tailored the trading algorithm to trade so that management earn a minimum cash profit of 5% of invested capital per block mined. The evaluation must be prepared using a forecast period of 5 years. Crypto management have a required return of 16.5%. All estimates provided are the most accurate and up-to-date estimates that could be sourced. Solar system The expected cost of installation of the solar system is R7.79 million. This system should account for the installation of 100 , high efficiency 650W solar panels. The combination of the solar system and batteries will allow for additional cost savings. The costs to maintain this system will total R50000 per annum. Generators The expected cost of installation of the generators is R6 million. The generators would be used solely during loadshedding (you may assume no other material power outages will occur). Costs to operate the generator will total R100000 per annum. This does not factor in any future movements of the Oil price
