Due to recent changes in crypto regulations in the United States I will be removing the in-game exchange. If you have an order placed in any market here that uses a coin as one pair please remove it as soon as possible. After an unspecified time the exchange will be put offline and all remaining orders will be cancelled.
Will it still be possible to exchange Anti-Matter for crypto (which is separate from the game's main Exchange)?
This will stay the same yes, only the player to player exchange has to be removed for right now.
Unfortunately, however, the way they worded the new regulations leaves it wide open for them to classify securities as they see fit without giving an exact definition giving them sweeping power over it. How that will affect the game we will have to wait and see.
