BitCrystals was invented on June 2, 2015 by the Swiss company Everdream Soft. It is a token linked to the Bitcoin blockchain through a trading platform. Everdream Soft is a Geneva-based company that invents video games, such as the mobile card game Moonga. The beauty of BitCrystals is that it connects an ecosystem built on top of cryptocurrencies with a new generation of poker. Every Spells of Genesis player must provide a bitcoin address to deposit and play cards. The number of cards is limited by blockchain properties. The new blockchain cards have different functions (spell, speed, attack, defense) and zero-trust treasures secured by the Bitcoin blockchain, which can be sold some weeks in exchange for BitCrystals.
