The main problem is that Cryptocurrency usage is banned in India and coming openly to state that you are doing mining means you will come to picture as it is illegal to mine cryptocurrency in India.
Your idea is good but for that it should be legal to use cryptocurrency.
As far as i understand there is no legislation that says that cryptocurrency mining is illegal, the only news till now is that the RBI has come up with a circular to the banks asking them to stop dealing with crypto currency exchanges, first thing with India is that the climate is not conducive for mining, you need to spend a huge amount of money to keep the machines cool because of the climate, there are places with cool climate but is it possible, i am not sure.
