How did I get a stone to be sold only for tokens? Or I can buy a stone for fiat money? Does the team communicate with the participants?
I don't think that the stone can be sold for tokens, but fiat too. You need a developer response for that, you have to be waiting.
We need some clear explanation on this even some video presentation would help better to understand it better if this can be explained in detail that can cut the edge and make it simple.
