wish you the best Poloniex Poloniex was better in 2021 than now but they let me withdraw my funds so I'll give 3 stars for the great history we've had. the downside was selling 40% lower price coz they blocked withdrawal of the alt coins I had, begun after the hack. I still like their interface, but now very little trading is happening.... wish you the best Poloniex!

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.

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.

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
