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.
Clams were initially distributed to 3,208,032 BTC, LTC and DOGE addresses based on the 12 May 2014 snapshot of these blockchains. Each of these address received 4.60545574 CLAMs. 63,381 addresses have been dug comprising 291,898.39 CLAMs. If all the distributed CLAMs were dug up, the total money supply would be 15,009,015.13. There is no Proof-of-Work stage for Clams and the network is now secured by Proof-of-Stake.
