So how can i use BCY in the game, cause i really dont understand it. Actually i tried to log in in to the game with new account(created on app) then i got message wrong account, and couldnt play anymore.. needed to install game again. Now i will not try to create an account again i will just play a game. And yes im holding some BCY on exchanges.
You can't use cryptocurrency to buy items in the game because of Google and Apple store policies.
BitCrystals are used to buy blockchain cards outside the game via Swapbots directly from EDS or third parties as well as on the Market on Book of Orbs and the Counterparty DEX.
