Don't attempt to mine unless you have a recent, mid-range/high-end/enthusiast CPU. Either a Ryzen CPU or a Haswell Core i5 and up.
Otherwise just don't bother, it will be a waste of time. If you plan to do it on a laptop you shouldn't either, you will run into overheating issues among other things.
XMR can be only mined via CPU.
I used to mine it but i dont think there is much profit in Mining via CPU.
You will need a good configured CPU to mine such coins n also you have to maintain the electricity cost.
Other Coins can also be mined on CPU by used CPU miners like nicehash, cryptopia, etc but they wont give you much but will increase your electricity cost.
You can try mining them and continue doing so if you think it is profitable.
Feel free to inbox if any help needed.
XMR has been able to be mined with a GPU for quite a while now.
