Replied them with an address of my deposit address on a casino. Obviously, I do not expect the $10 to come but just trying to see whether they will send it or not.
You never know, they might surprise you. Even though it is not a large amount, I wish you the best.

The DOGE coins that have accumulated may be worth some money, but I will not even attempt to retrieve my account.
2 weeks passed after I gave them my address but there is nothing come to my wallet till now. Surprisingly they are still regularly updating what is going on with them almost every day during this month (July). Latest update on their website as follow:
July 31, 2021
