BitCrystals are Counterparty assets which acts as game currency for EverdreamSoft’s upcoming mobile game Spells of Genesis (SoG) and trading card game Moonga. BitCrystals come about because the game creators believe that players should be able to keep their game assets outside the control of game developers' databases and like a normal economy, allow for free trade of the virtual goods. There was a crowdsale of the BitCrystals token where 70% of the 100 million total tokens were made available for purchase. The remaining 30% were given to early supporters and contributors. All unsold BitCrystals were burned on October 2015. A total of 974.13 BTC was raised during the crowdsale.
