... This is a cross-chain transaction
Really? I don't think this is a cross-chain transaction. Omni is just a protocol layer that is still one chain with bitcoin. cmiiw
I will reply support but before that I want to know your thoughts and What should I write them.. I found more post on bitcointalk which one got the same issue and Poloniex support solved that in 1 month but mine takes more then 6 month and dont have any solutions. I am afraid of that finally they will say me that it can not be recover. what I have to do ? Thanks..
I have no idea in this regard, maybe asking for things that can speed up the recovery process and your availability provides any information needed on it. 0.4 BTC is a huge amount from my point of view, maybe they can refund but need some investigation beforehand. The thing to remember is that you are sending btc from an address that you do not control. Your BTC is sent from the binance hot wallet.
