They're used for ranking and bonuses. You're placed in specific leagues based on the number of trophies you have, and you will get an X amount of bonus medals and star coins per battle won depending on the league you're currently at.

For example, If you have between 200-300 trophies, you're in Bronze League 2 and will receive 21 medals and 70 star coins per PVP battle won. If you have between 300-500 trophies, you're in Bronze League 3 and will get 22 medals and 80 star coins per win. Between 500-700 trophies will put you in Silver League 1 and you'll get 23 medals and 100 star coins per win and so on.
