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?
Budget like 1 btc you want to invest on solar system, it seems very ricks. Another thing you mentioned is that if the mining rigs you are looking to buy are old, there is a lot of trouble. Old stuff has a very normal life cycle so mining with old stuff is more likely to result in losses rather than profits. Because old things wear out more and the repair cost increases a lot.
