After 8 years: worst exchange in cryptomarket.

How it all happened: after the “hack” in November 2023, they closed ELON and many other tokens withdrawal and have not opened it since. Then they closed trading for ELON without warning and after that announced delisting and deadlines for withdrawal, which is impossible. I have never seen such direct and brazen theft of coins from users on any exchange, and many of them have been hacked and closed. And now they have installed an AI answering machine for the dissatisfied and bots in all social networks. Such clowns.

scam exchange

scam exchange, they froze the wallet of one of my coins in the portfolio, when i asked regarding that i was told that there is some error in the wallet and we are fixing it. I will be informed as soon as the wallet is fixed and then i will be able to withdraw my coins.

this never happened and after a month those coins got delisted from the exchange, and i lost my coins. When i spoke to their customer support regarding this, they just kept copy pasting me same messages over and over again. When i continuously kept asking i was blocked from chat support.
If you can move to another exchange please do so, this is not the first time i am loosing my coins on this exchange.

This platform disabled a crypto wallet and then delisted it

This platform disabled a crypto wallet. After 10 months they said it will be delisted so we have to withdraw the crypto. 3 months asking the support for withdraw the assets what is impossible because the wallet is disabled. Today it has been delisted and the crypto is lost. 8k lost for me. No support no information. What is incredible is that there are still no legal action against poloniex. sounds crazy and not believable but it is really true. Protect your assets NEVER USE POLONIEX

Poloniex was a legend in 2017 but its spreads tell you a different story now. I send $6,800 worth of XRP onward, observed Fidexy for a bit, and emerged with $626—insufficient to care about—$9.2% gained for hardly any effort. After one such loop like that, I’m wondering why I ever left sizable balances on Polo.

They stole my RLB coin by not letting me withdraw it. This is one of the worst exchanges. Take your tokens out as soon as possible and put them in Meta Mask or any other self-custody wallets.

BIG WARNING FOR INVESTORS

BIG WARNING FOR INVESTORS: POLONIEX REFUSED TO RETURN MY $30,000 USDT, CLAIMING ONLY A SPECIFIC TEAM COULD ACCESS IT BUT REFUSING TO ESCALATE MY CASE. AFTER MONTHS OF NO RESULT, I TURNED TO AN EXTERNAL TEAM.

My account blocked with no reason!

They froze my account and won’t even let me log in. There was no warning, and I haven’t accessed my account in the last five years, yet now they have blocked it! However, I still receive their promotional emails. I contacted support, but I haven’t received any response. I had several transactions there a few years ago, but now they won’t even let me log in! What is going on? Where can we take legal action against them?

Poloniex Frozen My Account and Funds Are Unrecoverable

I made the mistake of leaving funds in Poloniex, and now my account has been frozen without warning. I provided funds from a now-defunct exchange, meaning I cannot meet their proof of asset source requirements, which makes recovering my funds impossible.

I have contacted Poloniex support, but they are asking for transaction details that I can no longer retrieve due to the closure of the original exchange. This situation is unfair and unacceptable, as my funds were legally acquired and deposited before my account was frozen.

Poloniex should review their asset verification policies and allow alternative ways to prove fund legitimacy. Otherwise, they are simply seizing customer funds without a clear resolution process. I warn others to avoid leaving assets in Poloniex, as they may freeze your account without viable options for retrieving your money.

They were the best exchange few years ago.
Not anymore. I don't have the energy to write this story now, but anyway, they are now located in Panama.

Poloniex no longer trustworthy since recent hack

I trusted and was reasonably content with Poloniex since about 2016. Then Google Authenticator 2FA "lost" my Poloniex account so I could not log in. Now I'm being asked by Poloniex support staff Min Han and Christina He (SE Asia) for proof of ID and transactions way beyond what international banking or border control requires (wife Chinese and UK/Europe border control officer). It's so far taken several days with every excuse being used not to let me in. Former pilot entrusted airside and across borders, but not to Chinese operating from what looks like Singapore. They are causing a lot of distress to a lot of people. And trying to keep me from substantial funds. Wife says many Chinese change minds with changed wind.

What's next? A video of me swallowing bath liquid and blowing bubbles from my bum?
