Hello fellow gamblers I am brand new to the world of online gambling, and am hoping someone here can help me explain if the casino are allowed to do this: I got an account on this casino a few days ago, and today I made a request to withdraw $1500 out of my winnings of $2400. These winnings were made only from wagers of my own funds. No bonus winnings. But my request got denied, and the reason they gave was that I still had to wager $300 before being able to make withdrawals. By then I had made 10 deposits since becoming a customer, amounting to a total of approx. $1000. I understand wager requirements for bonus winnings, but had no idea that there can also be requirements for withdrawals, when the winnings are made from my own money In addition, I was also informed that the max amount allowed to withdraw was $1100.... Is this legal...? And if so, is it normal for most casinos to have this term? I guess I'm surprised at this, since at the other casino I joined a few weeks before, I won over $4000 and had no issues with withdrawing nearly the entire amount at once!
