 Who told you an S9 could generate 0.3 Bitcoins per month?  They lied.  You'd be lucky to see 0.06 per month and you'd have a utility bill of ~$100 (if $0.10/kWh for electricity).
That's providing the difficulty stays were it is for a couple of adjustment periods... which doesn't happen very often.

Thank you for your clarification

I saw it several places, some articles in internet and even a video talking about best hardware allows you to make about 3000 us$ per month, but electricity bill will be about 3000 us$ too... so, the information on the net is so weird

In this article for example: https://www.buybitcoinworldwide.com/mining/hardware/antminer-s9/

Author says:

According to the above inputs, the S9 will produce** 0.285 BTC / $159 per month** and 3.36 BTC / $1939 per year.

But 0.285 BTC is much more than 159us$... this motivates me to ask here

That article was last updated on June 27, 2017, when one bitcoin was worth $2,396.78, according to BitcoinAverage.

And that section describing the S9's projected earnings was most probably written way before June 27, back when one bitcoin was worth approximately $557.89 ($159 ÷ 0.285 BTC = $557.89).

Thank you for your clarification Frodocooper, I will try to keep learning about this fascinating issue.

Never forget about the difficulty part too that holds the lead role in terms of "possible" earnings from an S9.
https://www.nicehash.com/profitability-calculator <- This looks to be one of the most genuine sites to give a possibly accurate estimation of what could be earned. An average of BTC0.002 - 0.003 can be earned according to current difficulty rates and the higher the difficulty adjustments be, the lower the earnings will drop.

I used to like that calculator as well. Just make sure to enter ALL the values, since it stopped filling in useful values for difficulty and BTC price back in August. I think the underlying calculations are correct as long as you don't accept any of the default values
