They made a mistake, but support corrected it in an acceptable timeframe I give Poloniex 3 stars, because my experience was mixed and not ideal, but support resolved the issue acceptably quickly. I transferred cryptos to the site several times without problems but the last time the transfer just vanished from my history, although the tokens did arrive based on the blockchain records. This shocked me and I immediately thought of a scam. I contacted the support and they responded after a few hours and told me, that the will forward this information to the technical department. After not hearing from them for 3 days I contacted the support again and they assured me that they are processing my request. Two days later the deposit arrived. So it took 5 days to resolve the issue, which is acceptable for me, but the errors on the website should be resolved in the future to avoid such errors.

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.

DO NOT USE POLONIEX ITS A SCAM They’ll let you deposit no problem and charge fees for trading but you’ll never be able to get your money back. Been trying to move some coins to another platform for weeks and they review each transaction then block it. Reason for block ( unfamiliar IP address or unrecognised wallet or similar). Support tool is a joke, takes you round in circles until you give up. Place your investments elsewhere.

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.

Worst platform Worst platform They change the price of the coins to make you pay extra 20-30% for transaction. Sells don’t process until you lower the selling price by at least 20% Unbelievable scam
