How nice of you to share another commercial with us.
But of course if you play too many games, you don't have time to catch the beautiful details of it.
Coin on the link is not a competitor with Xaurum, since it has a fixed gold base. Xaurum has growing gold base which is one of the features that puts it way ahead of other gold backed coins.
But anyway it's just a game for you, so why do you bother with gold backed cryptos anyway? Gold is for security, but in games you can use multiple lives and healing packs

Edit: The link is at least relevant for comparison unlike others that you have so generously provided to us
