I'm not surprised that some casinos doesn't want to have an inside exchanger. It's risky and takes efforts.
Will make a very simple, even childish example, why I wouldn't implement an exchanger if I would be a casino owner
Two players came. Player A made a deposit of 0.01 btc, player B made a deposit of 0.01 btc, and both decided to exchange it to xrp for playing. At that time price I (casino) credited to their balances, let's say, 500 xrp each.
Player A had a nice run, made his balance to 3000 xrp and now wants to withdraw it. Where the heck I should get these from, if there weren't any xrp deposited? How much of each coin should I hold "just in case"?
While player B didn't win or lose much, and now wants to exchange his same 500 xrp back to btc and withdraw it. Problem is - prices changed, and now it's worth not 0.01 btc, but 0.012 btc. So I didn't earn from him any, but still need to pay extra from my own pocket?
Ofc sometimes it works in otherwise direction, but still - risk is too big.
