The problem with adding Doge or Ltc is if they implement these soon there will be requests to add more currencies and they come a dime a dozen. But maybe Victor will think about it, if there's a huge demand for it.
Deny them. Simple. The only reason I said doge and ltc is because they are established and have been around for a long time. I understand if he chooses to keep it a btc casino, though. One can dream, though. One can dream...
