Profitabilty depends on several factors like current exchange rate, network hashrate, difficulty, your energy costs and so on. So there's no right or wrong answer.
To find out what to mine,there are several options:
- Multipools with profit switching feature (mining "the most profitable coin" in a certain timeframe)
- Coins with potential you think they will increase their value soon
- Established coins that will increase their value after the recent price drop
-

My #1 Multipool with profit switch is
https://hash-to-coins.com. You can use it as Multipool but also mine single coins only.
If you don't want to do a lot of research, you might want to stick with the established coins (LTC+Doge, WDC, FLO, MEC, QTL, NOTE, NLG, GLD,..). Collect them in a wallet (not an exchange) and wait until the price drop is over and they get a better price (compare with the past 18 months)
