If you are looking for good profit in the future you must first look at the MarketCap and Total number of coins. A coin with large coin supply (billions) can't grow very much in the future, not even 1$.
My choice: Masari.
It's a Monero fork, good relationshionship with Monero, only 18.5 millions total coin supply and it's still early, only 11000 sats on SouthXchange and Tradeogre.
If you count that Masari uses a weighted harmonic mean difficulty adjustment algorithm for smoother difficulty adjustment, fantastic dev which has been PR'd back to Monero you already have a kick-ass coin. It also has only ever used RingCT, has a fixed ring size of 13, and they plan on adding uncle mining and researching block tree sharding.
Fork and rebase with a lot of new features took place on 1 may with no issues.
Cheers !
