You could always LEASE the rig which seems to be more profitable than even multipools... But yes mining is dead unless you have a crystal ball that'll tell you which coins will explode in price xD
Don't need a crystal ball. Just do your research

There are plenty of coins that will rise in value in the medium/long term that are easy to spot if you do enough research on them. As for short term, it is basically a coin toss unless they Develop everything extremely quick or catch a hype train.
