How did you notice that its payout is nearly 0%? Did you play a game and didn't win anything? That is not what one should take as a reason to consider a casino a scam, though I'm not defending LTCCasino here since I've already read other replies and I've come to know about their reputation in the past within this forum and outside of it, I'm just generally talking.
Based on his statement construction, You’re right about his basis on establishing that this casino payout is nearly 0%. Maybe he lose too much on this casino without any record on withdrawing funds for a profit which is highly possible on any casino to occur if the user itself doesn’t know how to gamble responsibly.
When you feel or realize that a platform isn't honest or trustworthy, you should simply not use it anymore. There are a lot of other platforms which you can use to gamble which are totally trustworthy and honest.
This is the ultimate dilemma on many gamblers. Sometimes they are still playing on same casino because they feel that they need to chase there lose or the casino gets their money. They are clinging to recover funds that’s why they keep coming back despite they are not recovering anything but lose more in the process.
Some user look on the casino benefits too since some casino especially mediocre one promises a bonus that is too good to be true. This makes many user stay even if the games are somehow rigged or low payout rate.
