Hi,
I am thinking of investing about value equivalent to 1BTC at today's price 16.K in a dedicated solar power panels at my roof and use the energy produced for mining bitcoins.
If I buy second hand miners with 200TH hash power included in the package, how I would calculate time of investment return?
- As per my understanding of what you are saying, you want to mine bitcoin, using solar power to generate electricity when you mine Bitcoin? Why is electricity expensive in the country you are in or is electricity consumption cheap there? If you have a solar power panel you can somehow save on your electricity cost.
Not really, imagine the start up cost of building a solar panel. It will cost you thousands of dollar more just like stated on the earlier reply. Then you have to buy a second hand miner, at least according to the computation you can have a ROI at the shortest time of 2 years (according to joniboini) and longest of 11 years (according to philipma1957). That is not factoring the possibility of the solar panel or the miner malfunction during the operation which may turn to worst thing of not getting ROI at all.
Because from the tone of your story mate, it seems that you have an idea that the cost of electricity is also expensive when we mine bitcoin, this is if you first buy the surplus miners that are sold to you. But my suggestion to you, is don't get into that if you don't have enough knowledge about bitcoin mining.
The OP had realized that buying Bitcoin is financially better option for him.
