So what's happening when I can't sign my address? I've transferred from my Bittrex account. How can I prove it? I already created a report though.
You will be refunded after the investors with signed messages, I am in the same situation as you, and I also do not know what could be done to prove that (I did a screen from my bittrex withdrawal but Lauda does not seem to take it in account)
But you are on the investor's list to be refunded. It's already a good start.
