The game originally started on wax and later moved to hive. The game is now mainly focused on Hive and rewards handed out are Hive rewards for tournament's . You can earn using other chains also including wax, ethereum and bitcoin but our community at the moment is mainly hive users. Hence the market is a little higher on Hive.
The Wax market has been kind of forgotten about and as a result has lower prices where as the Hive market gets used more by the player base

Thank you for the expanded answer.
