remark on casino

Roll Fortune Casino wants $296 money bitcoin to cash out $4938 is this ok they said I could not cash out without the bitcoin fee is this normal

Roll Fortune Casino is wanting me to pay a bitcoin fee of $296 to cash out my winnings of $4938 is this a scam?

Hi, could you please send me the url of the casino because it looks like we don't have it on the site. I would try to see what casino it is and give it to our data team for review. 

$300 is quite a lot I would say, because the deposit is mostly to verify the method and not to be able to make a withdrawal at all. And it's usually a minimum deposit. 

So I would be careful.
