Maybe you like the US because most media comes from there? If you feel you don’t belong in Germany you can try other cultures too. From there you have access to A LOT of countries just a train trip away. And at some point you could go to the US too to see what it’s really like.
I never trade in. Every old phone I’ve had has seen more use than the value of trading it. Most go to a relative then back to me for some secondary use. Plus it’s good to have a backup device in case something happens to your main phone.
