❌ Warning about Poloniex! I’ve had over $400 worth of DONKEY tokens frozen for more than a month. Poloniex claims “technical maintenance” with no clear updates, no ETA, and no transparency, while the token is actively trading on MEXC, CoinEx, and HTX. Support keeps replying with generic templates. My funds are inaccessible and locked without explanation. Think twice before trusting this platform with your crypto.
They just froze assets. Took delisted assets. And so on. Scaming users. Support is stupid as hell and can only press buttons with predefined texts. Cant really help at all. Stay away from this scam exchange.
Maintenance coins for two years. And now they deliste them. Faking frauds
Beware of online scams! I thought I had lost all my money, but then I reached out to the company in the profile photo, and they helped me recover everything.
I submitted a support case months ago and I am still waiting for a proper help. I am never going to use this service again.
They list rare tokens so you move to the exchange your USDT then block withdrawals saying there is a temporary issue and then they delist the asset that they will never list again. I had thousands stolen with this trick. Their assistance service is trash that only copy-pastes the same answers again and again to everybody. Justin Sun is the scammer behind Poloniex and HTX. It is only a matter of time until he is sent to prison.
They have been blatantly lying to me for a year about being able to withdraw my assets to a wallet once they would fix a problem. They never did and after this time they simply delist it and said that they cannot check my balance anymore. They are trash of the worst kind. Thinking about all the stress and anguish about requesting again and again part of my life savings placed in this exchange… Its owners should be in prison.
This Exchange is completely a fraud. They have first disabled the wallet of my coin Dogelon, I have sent multiple tickets to ask when it can enable so I can withdraw my coin or sell it. But the same reply their support people were sending that the wallet is not working properly, so we have temporarily disable that wallet for uncertain period of time and we will notify you once the wallet is resumed and the coins will automatically deposited in your wallet. But in the meantime, they sent a circular about the number of coins which are going to delist from the exchange and the ELON was there. Now the wallet was under maintenance, and they sent the circular of delist the coin???? So, neither i withdraw the coin nor I can transfer because the coin's wallet was under maintenance. I completely loss my funds and I sent a message via X, to mark Mr. President of United State who can take a legal action on this exchange. This is just a fraud.
They steal from you!! Don't ever use this exchange, all my crypto is gone. No response from helpdesk. Don't ever use this scam
Trust me, do NOT use this chinese scam exchange, they screwed everyone! dogelon on maintarance for around 1 year and then they announced to delist.. gave us time to withdraw till 25 april but guess what. still cant withdraw. everyone lost money !
Scammers robbed my wallet drained it . Zero customer service, stay away from poloniex
Scam!!! Took over £7k from me and ran off.
They are full of empty promises and they will only waste your time and resources. I admire /simple change/. They take you serious and the returns are worth it.
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.
Ze stelen je geld zonder enige schaamte , oplichters zijn het !! Geen zaken mee doen ! You cant trust them they will steal your money ! Don’t trust them
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. 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
They refused to allow withdrawal, but thanks to the name mentioned above in the image for making sure all my pending withdrawal were possible

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.
