Sure am glad I decided not to invest in mining 
Good. I know people who have lost all their coins pre-ordering ASICs from Butterfly Labs. Fortunately, I was never interested in Bitcoin mining. Tried CPU mining for a week or so, but stopped after receiving just BTC0.0000001.
Could not imagine myself mining today, would be earning 100x less, or even worse than that.
Yeah mining was/is a whole hearted effort otherwise you get pennies for it all.
