Hey here. I want to try myself in casino playing, but I am really afraid of being scammed. Few years ago I lost a huge amount of money that I saved for a long time..
I also experienced the same thing as you but I didn't save much money in the casino, almost all casinos will freeze old inactive accounts and usually they will contact the owner to immediately withdraw money from the casino or give a warning, maybe you missed it, but there are some casinos that help to recover your funds and account , I think you should try Stake casino
Casino typically doesnt freeze inactive account but rather they charge a fee for every balance left in the casino wallet until it was depleted and this is the time account will be closed but all processed will be notified by an official email especially the notice before they apply all the actions.
In OP case, he doesnt loss his money just because he became inactive on playing. You misinterpreted his words about his money that saved for a long time that it was deposited in the casino for a long as the reason it became lost. I believe he plainly lost his long time savings to scam casino which is the reason for creating this thread and not your assumption.
