As these folks suggest, CPU and GPU mining are not profitable at all.
However, I am using my laptop for daily basis, and I have been running this software in the background called BitCoin Miner (Win 8 or 10).
I am getting ~27KH/s, about 4k satoshi a day. You can give that a shot just for fun.
I get it that it's just for fun. But I'm guessing that you are spending more like 400K satoshi in electricity to get those 4k satoshi BTC?
Instead I would look into another altcoin miner if you are just using it for fun. You will have higher payouts and exchange them for some mbit down the road.
