Mining bitcoins depends on your hardware (asics) and luck. According to alloscomp (https://alloscomp.com/bitcoin/calculator), You would mine 1.0000 BTC with 3051.999 GH/s, with difficulty factor of 46717549644.7; That's an approximation, if the difficulty goes up you might need more hashing power, if it goes down you might earn more than 1 BTC.

Antminer S5 seems to be cheaper and a secure asic, unless you have nearly free electricity, you wont ROI (return of investment)

I don't know anything about mining so would you please to tell me why is "luck" and what will decide "the difficulty" ?

Sincere thanks in advance !

i think with luck he mean, the price of bitcoin, if it rise quickly you can make roi faster, because the diff won't keep with it

the diff is decided by the amount of hashing power that is currently mining, the more hashing the more diff
