Every coin I have transferred off Poloniex has been without a problem. I have not had a single problem ever. I have withdrawn STEEM, Nav coin, Vertcoin, Stratis, Bitshares, Digibyte, ETC, XRP, SYS and BTC. Not a single time has my transaction been delayed for approval. And do you know why? Because I have level 2 verification and 2FA enabled. THAT SIMPLE. They know who I am, and therefore they don't need to manually check transactions for possible money laundering or financing of terrorism as they are required to by US law.
RE: My $500 SBD finally arrived on Poloniex, 3 weeks after I deposited it. My BALANCED THOUGHTS on these guys, after hearing every excuse in the book why they suck. It's whitewashed PROPAGANDA.
