i would like to see a different method of payment than paypal because exery time i got an unexpected error or it shows me that i don't have enough currency :(

I don't really know much about what issue you're having, but I believe Payouts can also be done through Stripe.

If you mean for purchasing something...

Seems that some games can only be paid for with Paypal, while others allow card (that's what I've noticed, anyway).
