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?
The question is how much is your budget for the second-hand miners that you say have 200TH power?
If we base it on the current price value of bitcoin (17kplus) with a hashpower of 200TH, you can earn per hour around 12.75$ within 1 week you can earn 89-90$ depending on the value of bitcoin, if you sum it up in a month it will be around 382$ or more if Bitcoin goes up and if bitcoin goes down it will be less than that, this is based on my calculations.
