Also its been partly owned and bought by Circle, a large Wallstreet backed firm who are notorious for giving their customers a run-around forever. You will never be able to withdraw your funds. Poloniex will find endless reasons and excuses as to which terms and conditions (small print) you happen to fall into and therefore cannot comply with their never-ending security procedures. It is in their best interests to withhold user funds and never return them. Good luck!

Terrible support / Scammers Terrible support. I Felt scammed, the platform does not allow users to trade decimal values of coins only full increments, how ridiculous... yeah sure keep all my dust, you scammers! I also want to add, the support is a joke, I made a live chat support request on the 15th asking for help and was assured by someone who did not care and could not spell, my request had been escalated and after the chat was "closed" - alarm bells - I would receive support from the specialist team, which never came, I then sent follow up emails every other day or so asking what the progress was, and to this date 22nd have still not received a reply, so i reached out to live support again, to be given the run around again. In all transparency, the initial request was resolved, but not to my satisfaction, and I still have open questions that are not being addressed. terrible support, terrible exchange. stay away.

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.
