I now own one bitcoin in my coinbase wallet. It feels good. I am not sure why it feels so good but it does. I have a good feeling about Bitcoin. I am already up 20 euro after today. What could possibly go wrong. 
Good for you, now transfer that 1 bitcoin into your own desktop wallet That bitcoin isn't yours, because you don't have the access to your own private key which mean they are the one who own that coin
Download a desktop wallet, it's not really that hard to learn
I suggest electrum
