I was thinking about this since some time and even today started writing something about it but closed the browser by mistake.

Personally I am getting around 500 coins every day, I suppose is based on my account type, but I really don't care and I don't use them at all. Well, I have to and I do use them when my "wallet" gets 50000 and I cannot get more unless I "buy" some avatar related stuff. Since I created my GeoGuessr account I never changed my account until few days ago when I changed the cap.

Totally different would be if the coins could be used for paying down the subscription and/or buying actual merch.

Something I've commented to the GeoGuessr support was to create some league mode, like in football/soccer, and not just that "world championship" where always the same people are playing. Having some league style games where everyone could participate, earn coins, use coins to participate, bet coins to win back,... but again, to have the possibility to use them for something more than just avatar parts.

Another possibility is to use them for donations. We've all seen different countries and places through this game, and not everything is green or blue.

I like the idea.

Make loot boxes purchaseable for a specific amount of coins, and you can receive special items from the boxes, maybe unique skins which can only be obtained from the loot boxes, double XP for a limited amount of time, or maybe even an extension of your GG subscription for a few days
