Hi,
we have used a temporary bitcoin address from a famous exchange.
So we can't sign a message from it,
DRZ
PS: We will abandon for ever the project in the next 24 hours and close this thread.
Nothing is temporary dude, everything is forever! This is crypto we have blockchain you know it?
Just open that exchange and you will find your withdrawal history, show us a total withdrawal of 70BTC even with a screenshot and we believe you.
But guess what, you've lost your login data to access that account, don't you say!
Not all the exchanges mix bitcoin, and anyway even if they do, bittrex and poloniex show in the history the address you've sent btc. And if we talk about bigger BTC exchanger they will show those information too, because I don't think you've used some secondary exchange to move that amount of btc. So, you've a lot of way to prove us your identity, or you can close this thread even now.
Bullshit are not allowed anymore.
