In long term:
- Ethereum.
- IOTA

both of these projects have great potential, I am sure that they certainly have a great future.

and medium term:
-- MINEX .

 this coin has great potential. Overall a good project but think I will move the profits to other coins and keep only part for a long time. There is a very generous banking system from 27% for 3 months

I don't prefer short-term investments.
