I'm not really sure why their withdrawal limit is so low while they provides many games where players can win huge with small bet only.
The daily limit is either due to a limited budget, although they claim they are not new to this business, or is a sleazy tactic to keep the user's money hostage for as long as possible knowing that most users can't resist the temptation to spend more hoping they will double their profit.
As I suggested before, the best way to solve this issue, if they are not going to remove or at least increase this limit, is to add a
vault feature where gamblers can lock their funds.
The first one could be the reason, LTCCASINO is a new casino it's possible that they don't have that fund although it's an industry practice that casinos will try to limit withdrawal so they hold the winning funds to temp the winner to play, if OP can control his urge to gamble he can just withdraw daily and let him have all his winnings first before playing again, it's interesting to follow this thread so we'll know if he can withdraw all his earnings, lose it by playing again or the casino shut down because they cannot keep up, let's see what will be the outcome and the ending.
