Personally I don't think Bitcoin mining is still as profitable as it once was, those who benefited from Bitcoin mining are those who actually started at the early stage or some years back. Bitcoin mining consumes power, which means you would have to spend more in settling bills when mining, Bitcoin mining could also damage your system if not done the right with the right equipment. Which means you would have to spend on buying equipments, another factor is that the earnings from mining are pretty slow.
