So... ive read what you've written and it makes no sense? What are you asking? If selling hash to Nicehash is profitable?
It all depends on your electricity cost and how much you pay for the miner. No miner off the shelf does 15Th anyway, so I think you better do so reading and educate yourself before you buy something and overclock it and burn it out.
I think he wants to buy hashing power from nicehash.
@OP
Please do something about your English it's not understandable. If you want to buy hashing power from nicehash you can do that and there is no risk involved like other companies that sell hashing power. In case I misunderstood you you can also sell your hashing power to nicehash. if you want to determine profitability go on their site and type in amount you want to sell and you will see offers from people that want to buy it
