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.

SCAM ALERT. Avoid at all costs. Stole money from customers in 2019 when their technical incompetency lost them 1800 BTC. They called the theft "socialized losses". Most victims of the theft have not been reimbursed in 2022 still, 3 years later, even though the exchange is still running and in business. Customer service is being useless and dodging questions. Poloniex obviously doesn't plan on doing anything. There are many other exchanges out there. Avoid like the plague.

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.

Deposited 5K worth of Ethereum Deposited 5K worth of Ethereum, was pending, then it disappeared from the transactions tab and the chat is telling me last few days to await email, I checked trustpilot too late, but I will make a blog about this exchange and rank it on google, I will try to get a US lawyer and sue these mofo's. And I already started sharing this in private groups full of investors, SCAM exchange, stay away and don't get scammed like me. They transferred my money to one of the Poloniex's wallets, yet I'm still not given my funds.

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!
