After seeing their post on the gambling forum here https://bitcointalk.org/index.php?topic=5422931.0 I decided to try out their site and see what they have to offer.

I sent $503.9 to the wallet they made for me, using USDT on the ERC20 network.
The proof of this transaction is here: https://etherscan.io/token/0xdac17f958d2ee523a2206206994597c13d831ec7?a=0x5ce24b5b182cc6afa973940883292b953a93d9b2

to verify that this was sent to the correct address, I've attached 2 screenshots of the address they gave me, plus another from the link above showing the addresses are the same.

After about an hour of my deposit not arriving, I contacted support and was told it could take up to 24 hours, so I waited.

24 hours passed and still no deposit, so I contacted support again and they told me my deposit has still not arrived but not to worry.

48 hours passed and I started to worry, they emailed me regarding the issue and asked for verification of the transaction on my end, which I was able to provide, along with the information above proving that the transaction had been sent.

I contacted support again and was told that once approved the funds would be added to my account shortly.

4 days after my deposit, I was sent this:

I believe this to be a false claim as the wallets are identical and the money was transferred from the wallet I sent to another wallet within a matter of minutes. I presume their crypto handling provider.
I've shown proof that I've not made a transfer to the wrong address by providing screenshots. '1. Making a transfer to an incorrect wallet address.'
And also proof that I've not made incorrect transactions between cross-currencies, as it's been transferred on the blockchain in the link above 2. Making a cross-currency transfer (For example: Making BTC transfer to an Ether address.)
I have sent all this proof to them regarding this and am waiting for a response. If credited my funds, I will withdraw the accusation and believe it to be an error within their system.
Until then, my advice is to stay away from this site.
