If you had even one rig you did not say that. Even properly configurated rig with a good watch dog needs some attention. Also you may want to switch mined coins to increase profitability, search that coins from a bunch of shitcoins like some funny boys suggest here. It becames a big full time job 
Foolish boy. Did you really say mining is a "big full time job?" Do you carry your pickaxe and mine with it all day?
If you had even a clue of what you are doing then you will know that a well configured (not "configurated") rig will run for weeks without problem. Do you switch algos/coins daily? The answer is no. Only newbies who don't know what they're doing will follow whattomine's daily profitable coin. Go back to school dad you're drunk.
