The reality is that chasing new coins, creating wallets, dealing with shaky exchanges, etc. is a lot of work and takes experience.

It sounds like you are a beginner, so you will/should start out on Nicehash while you learn.

For example:

I have an extra Nvidia 1080 ti running on Nicehash with some rx580's.  A few minutes ago it was mining Lyra2rev2 and had an income of $1.88. (Nicehash has had lower earnings the last week, part of the game)

The card uses roughly 200 watts of power at $.14 per kilowatt, so consuming $.68 cents a day .

A profit of $1.20 a day. Since the card cost $800 (if you are lucky), breakeven, just for the card, is 666 days.

So, $1000 a month of PROFIT, would be $33/day.  at $1.20 per card, you would need 27 cards.  

At $800 each you would need a $21,6000 investment, just for the cards.

You would also need motherboards, power supplies, etc. enough for 5 rigs (6 cards each), probably $400 rig each for another $2000, totaling $23,600.

Those 27 cards would generate $33 or so a day, which means $23,600/$33 = 715 days to payback, or 23 months at which time THEN you could profit $1000 a month.

(Except the coins you are mining will be increasing in difficulty, and you will experience down time for hardware issues, windows updates, etc.)




Best case:

If you did get experience, and spent a lot of time chasing mining software, wallets, etc. you might gross $4.00 a day per card, after electricity ($.14/ kW) your profit is  $3.32 per card.

Then:
 10 cards required, $8000 invested, 2 rigs, at $400 each, totaling a hardware investment of $8800

Breakeven is then $8800/$33 = 266 days or 8 months.

So, after at least 8 months of mining you could make a profit of about $1000 a month.

But wait... we need to talk about taxes....
