> on why using credit cards for videogames is a bad idea: You trust the game owner with your payment credentials, and while this is fine when using Google, Facebook and Apple “wallets”, indie developers like us don’t have access to the same level of trust.

This does not check. They refuse to hold cc data on a security promise but are willing to host bitcoin wallets. Bitcoin laying around on game servers sounds like a good target to me.

They would be much better using a third party for cc payments, regarding security at least.
