If this is legit, I am sorry for your loss, please contact support @ Polo. BUT....newbie account? Loss claims? I've traded on Polo since it started and have NEVER had a problem.
Yes, this really did happen. Ive traded on poloniex for years as well and never had a problem. Yesterday after buying Ripple I set my STOP-LIMIT and all my coins vanished. No trace of the transaction. Poloniex disabled STOP-LIMIT feature shortly after. Ive had a ticket in for 19hours now. Still no coins or reply. You'd think poloniex could at least make a statement about the issue on twitter.
