It surprised me some time ago when I heard a guy said he saves his funds in his casino and sports bet account, then I was like how can someone take such risk to save his funds in his sport bet account maybe he trust the security of the site better that bank.
But sincerely it's not the safest place to store or Keep funds for security purposes.
Many don't care about the casino site they are using, they are only interested in using any casinos to get what they want.
Does he really understand casino websites? Or did he make the arrangement because he can't just withdraw that money like that again and there is possiblity for him to lost all if he had to wager before withdrawing them. I don't think the guy understand the implications of keeping his money in casino.
And I also do wonder why casinos which have built a reputation over the years will just decide to exist scam when there is enough for them to make in future, adding to what it cost them to get where they were before existing.
casino that has a good reputation and running away with gamblers money has two factors of doing that. Firstly the owner that was there with good reputation is no longer the owner or the casino has changed hand. And secondly it is a pre-plan arrangement to do that for a very long time. But overall that is very bad. Because if a casino had a good reputation, they will make more profit that the money they will run away with because as a reputable casino, there will be gamblers always.
