Mining Bitcoin directly is not going to work, not for profit. If you want to mine bitcoins at a loss as a learning experience - then go for it.
I was late to the bitcoin mining game, but did some mining when ASICs just came out. Those are CPUs designed specifically for solving the bitcoin computations, custom made, quite expensive but the only thing that ran a profit back then. Right now, you need newer generations of ASICs, cheap hydro/geo power, cheap labor AND economies of scale (all of them!). It was fun while it lasted, and not nearly as profitable as those early day miners...
You could probably mine some altcoin, and exchange it for bitcoin. I've never tried this.
