XP and Level system in Cortex

I have spent quite sometime, earning Razer silver and playing various games through Razer Cortex both on Mobile and PC. I have seen that completing various tasks such as acquiring daily loot, playing a paid to play game, completing TapJoy tasks earn you XP that help you level up. However, I have failed to understand what happens when you level up. Is there any incentive or something you unlock or is it there just for show and doesn't really serve any incentive or specific function ? Thanks for reading :smile_:
