Help breaking into the cryptocurrency world

Fellow humans of steemit,
I need some help. I have been trying to learn about the world of cryptocurrency but I am having trouble finding the info that I want. Or possibly it's just I don't know how to find the info. So...I have a few questions:
What advice would you give to a newbie In this area?
What currencies do you think are worth looking at?
What wallet and exchanges are the best?
And lastly any other helpful tips that you may have.

I sincerely thank whoever can be bothered to cater to my possibly moronic questions.
:) Have a groovy day
