Well, as what you have said, you have had enough of trading already. Which means you have been doing it a lot in the past and already have if not a lot, a little experience with several altcoins out there.

So instead of suggesting altcoins to you, i will advice you to look into all the altcoins that you have traded  in all the time that you have been trading. Not just yhe altcoins that you still have but also the altcoins that you have sold already. Check every detail. The prices, the time frame of increases amd dips, the ideology of each, etc..etc.,

Doing so will guve you a hint on how to find promising altcoins out there to invest in. Just try it. That'll be a better thing to do than to rely on the suggestions of random people that you don't even know.

Hope you make the right choices.
Good luck.
