Hi,
I imagine that there's a currency in the game for the economy.
If that currency was a crypto-currency (like BitCoin or Dogecoin) it would allow players to convert their in-game income into "real money" (and vice-versa).
This would be a big move for this new kind of MMO, saying "Players can earn money playing our game".
The Organisations would have a real GDP !
What do you think ?
(The only problem I see is the that you could "pay to win" by putting real money into in-game money but maybe there's a way to avoid this.)
