Depends on many things, especially which coin you mine.
Right now I find MERIT (MRT) to be one of the most profitable coins to mine. Especially because it is a limited group of invited people in the network, so the distribution is fair.

Referral link is restricted here, dude! You should delete it!
Sorry I have deleted the link. It's just that you will need an invite to open a wallet.
Anyways I still think that the mining is profitable compared almost any other coin
