I guess it would be really useful to have the possibility to pay via an in-app purchase. Credit card and Bitcoin might not be viable options in many countries. You could increase the yearly price for an in-app purchase by what Google charges.
@nysatrok thanks for bringing this up :) google play's in-app purchase mechanism is not my favorite but is probably something that users expect. I hope to support this in the coming months.
