I'm not sure whether you appeared here after getting my email or not. But thank you for clarifying the situation.

Your deposited amount was equivalent to $20k, where you have wagered only $100 with that. It doesn't matter how much you have wagered on Bustabit. Although, Luckydice stands with 'No-KYC', but I think the KYC verification was reasonable in your case. Think twice before making a large deposit on a casino to withdraw it after wagering a tiny part of the deposited amount.

Hello!

We have been in the market for 4 years with Luckydice and 8 years with BitKong, making our company one of the oldest in the market. Throughout our long operational history, we have required KYC from only a few players whom we suspect of money laundering. One such player deposited 0.57226183 BTC and, two minutes after the deposit without making any bets, withdrew 19,308.86 USDT over the Tron network. According to our terms of use (https://luckydice.com/en/terms-of-use exchange section), the exchange function is solely for game-related purposes, and deposit/exchange/withdrawal is prohibited. We are not an exchange, and in the event that our site is used as an exchange, we require certain documents to protect ourselves against potential future government inquiries regarding such transactions.

We typically resolve these kinds of issues within a few hours. However, since the deposit was made on a Friday and our team, which handles this does not work over the weekend, it took a few days. We hope everything is clear.

Here is the link to the transaction:

Thanks!

It's true that's there's no info on their website regarding the asking of KYC. Can you still login your account? Can you share screenshots of your account status for the withdrawal and the convo with their CS. It's hard to call them here since their rep here is inactive anymore.
