@philipma1957 I don’t think these two are only important aspects of successful mining. Choosing a reliable and transparent mining pool is equally important as well as having powerful hardware.
Finding a reliable and trustworthy pool is easy with several that are well known and trusted so that part is not a problem. Finding low cost power is the hardest part of the equation.
Definitely finding a low cost hardware is the deciding factor whether mining is going to be a profitable venture, or just a waste of time.
