Hello dear friend,
If you want to keep it small and learn about setting up a mining rig I would suggest starting with NiceHash.
They offer a fully self setting up GUI that will test your system and have you mine the most profitable algo.
They use your mining power to rent out further so you will be payed in BTC.
Witch isn't a bad thing since you can trade it into any other promising coin out there.
After that you can see for yourself what you want to do.
When you know what algo gets mined best on your rig, you can go and look at profit calculators. Some times you'll be better off mining a coin and holding it. Sometimes it's better to have btc and wait for a dip to get in...
I wish you the best of luck and hope this was helpful
