on hashnest buy hardaware should come? If itself earns?
I don't quite understand your question. but Yes Hashnest is basically a cloudmining company run by Bitmain.
You can probably find all the information on their site itself
should arrived hardware for me ?
Aditionally, give

Back onto the original question of rentability, I tend to believe that mining has left that area unless someone has renewable energy sources and bought used hardware cheap, and can do maintenance on it.
