I have never heard of that casino, they are accepting 60+ crypto as deposit method but they are only allowing withdrawals in bitcoin. However many other fiat based casino only allows deposit in crypto and withdrawal in fiat.
Gone through their FAQ section and found this;
1. Bitcoin -Players' preferred option -
Minimum payout: $25 USD
Maximum payout: $10,000 USD
One payout per day up to 5 per week
Also no further info is required for bitcoin players which is good point for crypto users.
