Despite the fact that we hear a lot about Bitcoins I've never seen it being supported by any major payment processor. None of the services I use such as PayPal, GitHub, Patreon or even the more independent ones such as Liberapay accept Bitcoins. If I wanted to accept Bitcoins I would need to register to one of these websites with insane security checks and provide a lot of information, and I might get 0.00000000000000015 bitcoins after 6 months (I've done it at some point).
So it's not really worth it. As far as I can see Bitcoins is for fraud, money laundering and other crimes but not suitable for legal activities. I certainly appreciate you asking though, and I think it means you can keep enjoying the app for free
