with what you are projecting as a revenue opportunity would take more then 3 years to pay back your initial investment.. keep in mind that every month the difficulty will go up and this number will rise.. it could be longer, i would count on it taking 5 years..

at that time, those miners will be useless and not making any money.. unless the price of bitcoin goes up with the difficulty.. but then it would be wiser and more profitable to just buy bitcoin and hold it for 5 years..







it looks like someone jumped into bitcoin mining, bought a bunch of miners, then did the math after it was all up and running.. figured out after a year they would never get their initial investment back.. so they come here and try to con someone into buying them out.
