Awesome question, and glad you want to get into bitcoin! As I mentioned to someone on one of my previous posts, there are a few things I would do to get familiar with the technology and the market before you invest.
I would suggest watching the documentary on Netflix called "Banking On Bitcoin". It explains a ton about how blockchains work, how Bitcoin works, and how it is secure. After that, you should have a decent understanding of the underlying technology. Then I would go to Blockgeeks.com and read more about it there. They have great explanations on cryptocurrencies that will further the knowledge you got from the documentary.
After that, set up a coinbase account so you can buy your first coins! If you have one already that's great. But if not, you can use my referral code here: https://www.coinbase.com/join/59550a905300330973150a88 .
By signing up with that link you will get $10 free of Bitcoin when you spend $100. Hope this helps!
