I did an analysis of all the hardware that was released for mining Bitcoin. They are based on FREE ELECTRICITY. They assume the miner withdraws fiat USD profits every week. They are also priced in US Dollar at the time of release.
Reason why I didn't do electricity calculations is because most miners are usually sold to 2nd/3rd owners with access to free or cheap electricity. This list just shows which miners made its owner the most profits.
I will try to do more Gen 1/2 ASIC equipment. If you want me to analyse a particular miner, let me know which one and if you notice any mistakes in the price or delivery dates of any of the equipment below.
