See this limitation I was furious in the beginning, but as days go by I am understanding the move in this regard. This could prove sane for the economy from NextColony and let's us power up and build up more on our Planets.
But in order for the vision to work I think the game needs quite soon to have a market at every player disposable, by trading IN and OUT of the game using STEEM or TRON as possible options. Do you have any target on this or time line?
