Why even bother mining for a few pennies- dollars per day. All the time you spent doing research, setting up your gear etc, you could just make a lot more money working a regular job. It makes zero financial sense.
While I agree mining is not as profitable as it used to be, doing research and setting up your gear doesn't take so much time (if you know what your are going). You can easily be working a regular job in parallel to mining. Mining is a set and forget operation. Once set properly, you can forget about it and do other things. As long as you have a profitable margin, that is.
