So even when u use nicehash or a mining pool, it's very hard to get your money back?

So after having some looks at bitcoin mining and setting up nicehash on my pc (single gtx 970) to have a look at how it works (ofcourse I won't be able to make any profit because of power consumption), I wondered if buying an Antminer S9 and starting to mine at home with a powercost of 0,26$/KwH would be profitable or will I just lose my investment.
