In-app or paypal

Hi developers.
I have an online game. And I want to know which one can make more money for us. In-App purchase or using PayPal?

Please consider that we have to pay between 30% to 40% as the fee to the Stores (Apple App Store, or Google Play), but PayPal fee is very low.

If any one have experience in both two, I'll be grateful and appreciate if he shares it with us. Thank you

Apparently everyone tries to avoid 30% fees but it’s not working
