What do you think about big companies making huge mining centers? And what about when those companies make it in other countries? How do you think this impact on those house-made mining structures, if does?

I've just read something and this came to my mind. Because as we know, as more miners we have, less the payment we receive.

Do you think it will become a problem in the future and will be impossible to a regular person to start mining?
