When we could start generating income out of tokens by mining in-game and in-game activities.
I don't know if you have Rush tokens or not, but if you have, then you should certainly join the official
discord. The closed Alpha is going to launch very soon!!! And the full release will be somewhere near Q3 2018, where you can use your tokens to build your mining colony.
I am in the project since pre-sale. And I also tested the very first version of the game. Good graphics, awesome idea. But it has been a long long time to wait.
