CoinCasino is definitely your best bet here. They offer 5-15 minute withdrawals which is basically instant, and they support multiple cryptos including Litecoin. Their welcome bonus is pretty generous at 200% up to $30k with 25% cashback. I’ve been using them for about 6 months now and never had to submit any KYC docs. The game selection is solid too – over 1,000 titles including all the popular providers. The only downside I’ve found is they don’t have a native app, but their mobile site works perfectly fine on both iOS and Android. Their wagering requirements are reasonable at 40x which is better than most crypto casinos these days.
