Something that was inspired from Xenoverse 2. Every week in the game players would get 40 TP (Time Patroller coins) from the system/devs/whatever. This idea is similar to that in which every week players would get a small amount of Wagu coins (5 coins sounds reasonable). This gives players who aren't able to donate to still get some tries on Wagu Machine without breaking the coins you can buy from Cash Shop due to Wagu Machine being so popular.
So thoughts on the idea?
