try just to stay around bitcoin for now, and keep the eyes on the altcoins, just jump in when u at least understand how the things work.
True. If you want to make a safe and smart investment, then focus on Bitcoin. It won't let you down 
Of course, if you are looking for an exciting project, then make a research of ICO, but as it was said, that's going to be a long term investment. Don't expect for quick profit.
