Hi i see the network of bitcoin have not many miners like i thought because of pools i guess, is it possible then
to start solo mining for example with 25 TH/s and catch block with little luck??
Thank you in advance for your time.
I actually prefer not to solo mining as its consider gambling. And I prefer primedice for that..
Well not everyone considers mining as gambling

You can definitely catch a block solo mining at 25th/s. But there is always a factor of luck with it .
