No, mining is absolutely unprofitable. The reason is, most people who buy mining equipment are unable to make basic arithmetical calculations, and buy miners at over-inflated prices, so all of them will lose money. The profitability calculators available on the net are mostly put up by miner manufacturers to mislead the public.
I knew it when I bought my U2
But i have done this choice because I wanted try mining with a new first hand miner.
No need to be Einstein to understand that mining 500 satoshi or so per day is not profitable...
But I can say...I am a miner (lol)
By the way...
if someone is a micro miner like me...
I propose him to mine in my team and so he has less withdrawal fees or perhaps it allows him to get satoshi quicker than alone.
