If you want to make a lot of money off it fast then forget about it. You can make a few pennies here and there but don't expect to get rich of this.
I do it more for a hobby. Research some coins that may interest you. See if they have potential to go somewhere in the future. You may want to invest something into it after doing your research. I look for ones that are on the extreme cheap side atm

Mining isn't for profit unless you've got free energy or the price of your coin(s) will increase considerably. Mining is to protect the blockchain, processing transactions. So if you're only for profit, you better use FIAT to buy coins. If you want to support the coin you like, go ahead.
