I would like begin this post saying offenses, but I will spare and respect you reader. I have been using Poloniex since 2012 and have never had any problems with deposits, withdrawals, trading, etc., everything was perfect. But I realized from a few months until today that everything has changed. The symptoms I see is a total abandonment with customer satisfaction that credits (invests) and entrusts them their money.
The first symptom was the deletion of the Trollbox, which, although the Trolls actually appeared there only to FUD, that chat was what "warmed" the negotiations and was the first support contact with this exchange.
Second symptom is precisely the problem that I am facing today that is to deposit my money in Poloniex, not see my money arrive in them even the address being correct, send a support ticket and after 9 hours, have no response.
I deposited 30 SBD yesterday at Poloniex...
Here is my deposit slip
I went to check my deposit on 
For many here is little money, an insignificant amount, but for me it is not. I'm not a "Steemit Celebrity" who earns for example 300, 400, 500, 1k SBD per post, is every day on the trending page and I don't have the whales by my side to ensure this. I live in an underdeveloped country where every dollar is very valuable and these 30 SBD are sure for me missing because only I know how much I worked and waited to earn those 30 SBD.
My support ticket for Poloniex. 9 hours and nothing
What revolts me beyond the incompetence of Poloniex in not responding to its users in their deposits is the silence of those who make the Steemit platform. No communication on 
I hopefully went to see the SBD page today and look at the surprise: "Deposits and withdrawals suspended".
