I am very new to the whole cryptocurency thing and this isn't the first time I have heard something bad about Poloniex. I couldn't even imagine investing nothing but time and money to build up my SBD/Steem only to have Poloniex do what they do and all of a sudden its missing.

I hope they are able to assist you and compensate you some how because that is just horrible. They are coming off as some shady bookie at some back alley casino!
