Look at my post on the previous page, and just google Bitcoin mining calculator
Calculator is certainly good, does not always coincide with reality, but wanted to know about the real possibility of my S9.
I will not distract .... sorry
No worries.
For solo mining, if this pool mines at around 7PH/s (7000TH/s) and finds a block around every month, your S9 at 13TH/s lets say is about 0.18% of the pool. This would mean that it should take around 555 months of mining for 1 block on average. It could take 5 mins or 5 years, but that is the estimated average over time. This could also increase with further network difficulty too.
555 months? a long time of course .. but anyway thanks for the information, I'm going to probably look for something easier
