how possibilities wit OP available sending USDT TRC from Binance to Duelbit account actually impossible sending using TRC network in Binance to wallet TRC USDT in duelbit. Its seems impossible for sending with address start first 0x as USDT ERC20 network.
But how possibility with OP can get Duelbit deposit address with USDT TRC network if there in duelbit gambling platform not support TRC, drastically difference address kinds between ERC20 and TRC because when wrong kinds of address can't sending fund. I don't understand yet about problem if wrong network usually in exchange platform we need to pay fees service and they will return back our fund.
I am not the OP but let me explain about the transaction. Op has taken the wallet which is of TRX. And deposited USDT to the wallet and it has not occurred any problem as it is a TRX wallet. The problem is that wallet is TRX and that's why it couldn't be deposited on the wallet. If team can add manually then it may work otherwise it is not possible.
The other problem is that the USDT that Duelbits is using is on Erc20 and not TRC20, i dont know if it can be recovered manually but i do have the same problem when sending up another chain as deposit on Binance on which they do ask out for some BUSD fee for that recovery service, so i had paid for that and successfully retrieved those funds which is really that good but i dont know if this one would really be applicable or could really be that possible on some certain conditions or situations.
The only thing duelbits can do is send your USDT-TRC20 back to your address because they only have USDT options on ERC20 and BEP20.
But unfortunately, I doubt they will do it to return your deposit because there are many cases like this, and every time you make a deposit there is a warning about what will happen if you make a mistake to the deposit.

Sorry for your loss, it's not a small amount of money and it's hard to accept this loss, but it's a lesson to be more careful, always double-check before pressing the send button.
However, if in the end Duelbits is willing to send your money back, that should be appreciated.
If ever that Duelbits cant really be able to retrived it out then it would really be that an expensive lesson learned for OP which its
always been that recommendable that whenever you do tend to deposit thousands of $$$ then always double check out those warnings
because if they have stated that wrong deposits would be lost forever then there's nothing you can do.
