Poloniex used to be great in 2015/6 Poloniex used to be great in 2015/6. They have become worse and worse again as time has passed, coins/tokens have vanished and trading is near impossible within the UK now, my savings held in poloniex have vanished, I am completely frustrated and disappointed with them.

Definitely scammers Definitely scammers. Happy to accept deposits, but if you want to withdrawal, you have to full KYC despite their website saying only email for under 10k per day. No doubt if you do KYC, they won't give you your money, and will just sell your data anyway. Lesson learnt and money lost.

Extremely bad service Extremely bad service, been 5 days now since withdrawal request and nothing has been sent, All they have done is post a fake transaction ID. I have sent multiple requests and support emails to try and get this resolved but have not got any reasonable response from them yet. Be aware, suspect Poloniex may be about to Exit Scam everyone. DO NOT SEND ANY COINS THERE UNTIL THEY RESOLVE THIS!!!

They're holding my funds hostage Back before Poloniex implemented KYC, they allowed people to deposit as many coins as they wanted. Then, without warning, they implemented KYC and are refusing to allow people to withdraw funds until we give our SSN and a picture of our passport etc. They have already been hacked before and they have a BBB rating of an F so there is no reason to trust them with this much sensitive data. Protect yourself and STAY AWAY.

Poloniex & Circle are a SCAM!!!! STAY AWAY!!!!! WARNING - DO NOT USE THIS SCAM EXCHANGE!!!! Locks accounts leaving users unable to withdraw their coins. Absolutely no customer support whatsoever - all support tickets are ignored. This exchange is owned by Circle.com - look them up on TrustPilot - their reviews are the same, stealing money, demanding ID, blackmail, scam, etc, etc. Poloniex & Circle are a SCAM!!!! STAY AWAY!!!!!
