When it comes to fund and assets, It is well known that one needs to protect it with utmost care and caution. I believe you have heard this word here and it is very popular for members conversant with the crypto community and it says "not your keys, not your coin".This words speaks of volume because they say exactly what really happens in the crypto world when it comes to third party holding custody of your assets. Third party holding your assets does not guarantee you the ownership because they are not decentralized so therefore what ever they ask you to do, you must obey otherwise your assets are gone. This is the situation in which you are now OP.

When it comes to business, you should know that every organisation looks for a way to maximize profit which casinos are not left out and I believe this is the situation in which you are facing now as the amount of asset discussed here is not a small amount if we are to look into it. You should have withdrawn your assets long enough  to protect and save yourself this stress. It is better for you to do the kyc and get your funds as they will tell you they are acting in accordance with government policies to safeguard themselves even though there is nothing for them to hold unto. This should be a lesson to you so in the future you do not entrust your funds to any third party what so ever the situation is.
