Yes, of course , you can completely cash out Litecoins . After all, the casino treats it just like any other currency.
Just keep in mind that most crypto casinos, just like standard online casinos, only allow transactions in the same currency in both directions . So, just as you would expect to deposit and withdraw funds in, say, Canadian dollars, you can deposit and withdraw funds in LTC. Needless to say, if you made a deposit in another digital coin, you won't be able to switch to LTC to cash out. But you can simply cash out that cryptocurrency and then exchange it for Litecoin on any cryptocurrency exchange.
