such as the California gold rush back in (18481855) no miners ever got rich, only the business associated with the miners ever made any mentionable profits.... history seams to be repeating its self in a sense but in a digital way. trying to transfer/spend/convert your digital currencies require you to pay fees not to mention if you do get to convert your coins to cash there is a fee to get your cash and even pools taking from 1% - 3% right off the top. I see no way to actually make a descent profit by mining.
Setting up your own public pool and bleeding other miners seams to be more profitable in the long run.
or perhaps Im just having a bad day.... the above is only my opinion thus far.
