If you are still looking for profitable alt coins to mine, why not try to mine ETH? The price of it now is very promising and it's increase is realistic. Also it's good to consider Zcash, I have a lot of friends that are mining with it and it is profitable for them. I want to mine but still I don't have my own rig but it's convincing me.
I read ETH is proposing to switch over to POS in near future so make future you will be spending at right time for mining rigs for the case of planning to mine ETH.
I am not sure why you people are looking for getting into process of mining as it will not be profitable in all the futures whereas trading will be consistently profitable for our life also over time we will be getting more experience so that we will be getting chances to make more profits. But mining profits will decrease over time.
