I spend most of my time trading short term. I've got some long term investments running in the background, where I almost never look at.
However, trading short term (daytrading) requires some skill, while long term investments are relatively easy to do.
If you have experience, go for daytrading, cause it can generate a lot of money when you are good. If not, play it safe and go long term.
For me, daytrading is alot more profitable for me, but it requires alot of my time aswell. Long investments take 0% of my time.
I'm currently holding Cardano, Verge, EOS, NEO and some others. Pretty safe and solid investments in my opinion.
But my advice to you is: check out coins yourself, compare them and decide whether you wanna invest in them.
Good luck!
