This is my math.
If a reader support me with an ink value of 100$
All the ink is form app purchases with a 30% fee.
Then I have a value of 70$.
Tapas takes the share at 15%
Then I have 59,50$
The PayPal takes 10%
It gives me a value of 53,55$
And If I have to pay my Danish tax of that income at 40%
I have a party value of 32,13$
Well. That’s just the name of the game.
