According to the AU Casino Seeker checklist, 21Bit Casino is suitable for crypto casinos. It supports BTC/BCH/ETH/XRP, etc., and the review notes fast crypto payouts, weekly tournaments, and gamification. For registration, you get a three-part package of up to A$2,000 + 3 loot boxes with spins, and then an 8-level loyalty program with points exchange is activated. There are some weaknesses, such as few table and live games, lower limits in fiat, and the chat not being in a prominent place. But if crypto is your priority, then this is more of a plus.
