Wow, I was fully expecting an inflammatory post, ridiculing alt coin miners...but I couldn't agree more.  I keep telling people,  you're going to have to do some work and actually think about what you mine instead of just pointing your rigs at whatever is turning a profit at that exact moment.  That is unsustainable, and is exactly why the bottom of the market has fallen out.  Gotta look at the big picture, or you might as well pack it up, cause you're going to be very disappointed.
