Don't just depend on recommendation and jump into it. Make sure to do your own research on the coins recommended. For my personal choice I like Ripple (XRP), Cardano (ADA) and TRON (TRX). They have use cases, lots of development and partnership plus the prices are cheap.
Each person has its own thought about his likely coin. You need to learn more about coins because they are all good and profitable, it depends on how will you trade them. Try to start with Nucleus Vision, Shivom.
