So basically if you buy lets say 10 GH from their website you are renting their mining equipment and you are getting same amount of BTC like you would if you bought 10 GH asic and mine for yourself minus fees?? So if you manage to sell your GHS at the same price you bought you have rented those hashes for free. In real life you would not be able to sell your $10K USD asic right away for $10K USD
