We need more Hive Engine games to adopt HBD in addition to their own tokens... For example, CryptoBrewMaster already use HBD for some game features.
It is very easy to hoard game tokens using multiple Hive accounts and then dump them bulk (en masse) on Hive Engine and that will crash value of both the game token and HIVE as people continue to cashing out the HIVE they get from selling the game tokens.
