Sounds like you can't deposit or withdrawal Petros from it. Left by one of the commenters on this tweet (auto translated):
I have more than 1 month Trying to Generate Deposit Address on your platform and Never Generates; Neither the PTR nor any other Crypto. I need to send my Wallet to PTR that I have in my petroapp and I want to create Order Flow in your Exchange
The Petro has been proven to be an utter farce multiple times over. Don't know why you are still promoting it.
