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.

It's Coinbase that owns your 1 BTC.
haha, seriously, just withdraw it from them to a decent wallet, i will never recommend to anyone to leave his bitcoins on any exchanges, is ok if you have some satoshis on them to trade for example, but in general never leave your bitcoins on any exchange.
Do not waste more time, dont risk your money, get a decent wallet and put your bitcoins there...
btw yes, owns some bitcoins made you feel better
