Thanks trendax, I appreciate your Insights.
It seems to me there's a substantial doctrine around mining, that I have to catchup with.

Another question that came to mind is about collaboration between miners and/or exchange of information:
1. To what degree do miners collaborate with each other (for example: purchasing miners in bulk, purchasing datacenter services , electricity etc) ?
2. other than Bitcointalk, and reddit forums, are there additional "spaces"/forums/groups/other that miners use to catchup on things and/or use for discussions ?
Thanks !
