Poloniex.com Review 2021 – Scam or Not?

NEWS: Poloniex is quite overloaded at the moment, the support is answering very slowly and the website itself is quite slow and using lots of your computers resources. At the moment, you can try Binance as a alternative for  Altcoin trading.

Poloniex is one of the most diverse cryptocurrency exchanges in the world. They provide a superb liquidity for the majority of altcoins, which can be traded against Bitcoin.


Tristan D’Agosta founded the exchange in January of 2014. The Poloniex executive level is kept anonymous, probably because digital currencies are still a bit shady business and they don’t have a license for offering exchange services in the United States. The company is based in San Francisco, California. They are focused on the United States market but tend to attract altcoin traders from all over the world as well.

Verification on Poloniex

The account creation on Poloniex is rather simple and can be done in under 5 minutes. The user provides necessary information and needs to click on the confirmation email in order to complete the creation of an account.

The verification process is similar to the verification on other exchanges, and it has two levels.

The first verification level requires email verification, first and last name as well as country of residence. When completed, the daily withdrawal is set to 2,000 US dollars, and margin trading is enabled.

The second verification level requires personal information, address, phone number and a scan of photo ID (passport, national ID, driver’s license) and a picture of the user holding Photo ID. It can take a few days for the staff to review the submission and to verify the account. In the case of any problems, a user will be notified to contact support regarding the verification.

When completed, this level of verification allows daily withdrawal limit of 25,000 US dollars.

There’s also a third level of verification which can provide limits higher of 25,000 US dollars. Additional details about the requirements aren’t publicly available, so users or companies need to contact support.

The exchange doesn’t support FIAT currencies. Deposits are possible only in digital currencies. The closest thing to FIAT currency is Tether USD, which is basically US dollar placed on the Blockchain.

The support for digital currencies, on the other hand, is enormous:

  • Bitcoin (BTC)
  • Litecoin (LTC)
  • Dash (DASH)
  • Ethereum (ETH)
  • Zcash (ZEC)
  • Monero (XMR)

And over 80 other popular digital currencies are available for trading on Poloniex. The full list can be seen here for registered users, or on the live trading screen for non-registered users.

Poloniex Fees

The trading platform uses a standard maker-taker model which encourages market liquidity by rewarding the makers with a lower fee. It likewise results in a better market spread, because it motivates the makers to outbid each other. This model is particularly important for Poloniex since they are one of the most diverse exchanges with over 80 supported cryptocurrencies and it’s a significant challenge to provide a good liquidity for all of them.

The users are charged according to the following fee schedule:

  • below 600 BTC – 0.15 percent for the maker, 0.25 percent for the taker
  • from 600 to 1,200 BTC – 0.14 percent for the maker, 0.24 percent for the taker
  • from 1,200 to 2,400 BTC – 0.12 percent for the maker, 0.22 percent for the taker
  • from 2,400 to 6,000 BTC – 0.10 percent for the maker, 0.20 percent for the taker
  • from 6,000 to 12,000 BTC – 0.08 percent for the maker, 0.16 percent for the taker
  • from 12,000 to 18,000 BTC – 0.05 percent for the maker, 0.14 percent for the taker
  • from 18,000 to 24,000 BTC – 0.02 percent for the maker, 0.12 percent for the taker
  • from 24,000 to 60,000 BTC – 0.00 percent for the maker, 0.10 percent for the taker
  • from 60,000 to 120,000 BTC – 0.00 percent for the maker, 0.08 percent for the taker
  • over 120,000 BTC – 0.00 percent for the maker, 0.05 percent for the taker

For lenders, there’s a 15 percent flat fee to earned interest.

The fees calculation is based on the last 30 days of trading volume for each user and automatically adjusts the fees according to the volume.

Deposits and withdrawals are free of charge on Poloniex.


The trading screen on the exchange is very smart. It offers multiple time frames, multiple-option candlesticks and both Fibonacci levels and Bollinger bands. This trading view is available for all of the 200+ trading pairs.

There are four primary markets on the platform:

  1. Bitcoin (BTC)
  2. Ethereum (ETH)
  3. Monero (XMR)
  4. Tether (USDT)

Each market has its own box and all trading pairs listed below. During last year, Poloniex accounted for over 99 percent of Tether trading volume and remains the only market with high liquidity for Tether trading.

Poloniex chart

There are three main order types:

  • Buy
  • Sell
  • Stop Limit

These orders are available for all currency pairs.

Similar to BTC-e, there’s a troll box – but despite the moderator’s effort, it can be malicious, and crooks are looking to trick the new users. Tip: it’s called “troll box” for a reason, information found in this public chat can’t be trusted.

The exchange supports margin trading, and it offers 2.5x leverage on some currency pairs:


There’s also a lending option, where users can offer or demand a loan with the certain interest rate.

The exchange currently doesn’t offer to trade futures and derivates at the moment.

Ease of Use

The interface looks great, and it’s easy to use. Shifting between more than 200 trading pairs is quick, and the website looks great.

There are no apps for Android and iOS, but the platform is responsive, and it looks good on mobile devices. Some third-party apps were made with Poloniex API, but the majority of users agree that these apps cannot be trusted, especially when it comes to trading with money.

Poloniex Customer support

The exchange offers support via email, ticket and directly from troll box. The fastest way to get the answer is by asking the moderators directly in troll box, but they are known for delays. The support isn’t one of the advantages of Poloniex – they take too long to respond, and the responses often aren’t complete. There’s also a knowledge base, but it isn’t extensive, and it covers only basic questions.

User experience of Poloniex.com

There are some scam reports related to Poloniex. Some of them accuse the exchange of tempering with Ethereum Classic and making organized pumps and dumps (artificially blowing the price up and then suddenly crashing it). The accusations remain without much evidence, but many users commented on the posts related to it.

The scam accusations mainly come from the users who haven’t received free ETC at the time, so it’s fair to say that the majority of accusations were biased at the time of writing.

The website of Poloniex is quite slow and it seems the developers did not do a good job here. Compared to other exchanges, it seems to use lots of resources in your Browser and if you have a couple of tabs opened at the same time, the performance of the site goes close to unusable.

Poloniex Welcome

Poloniex Security

Like other trading platforms, Poloniex offers two-factor authentication for both login and withdrawal authorization. Also, an email confirmation is required for withdrawals. The exchange claims that the majority of customer funds are held in cold storage, as well as that they are monitoring the platform 24/7 for any unusual activity.

The exchange was hacked in March of 2014, just two months after launch and at that occasion hackers stole 12.3 percent of Bitcoin on the exchange, which was approximately 50,000 US dollars at the time. The vulnerability was easily fixed, and there were no incidents since.

Poloniex wasn’t able to absorb the loss, so Mr. D’Agosta, CEO of the exchange, stated:

“If I had the money to cover the entire debt right now, I would cover it in a heartbeat. I simply don’t, and I can’t just pull it out of thin air.”

Instead, the fee was raised from 0.2 percent to 1.5 percent, and the loss was equally distributed to all customer accounts. After two months the balances were restored, and the fee was returned to normal 0.2 percent.

Mr. D’Agosta handled the situation very well, by going public immediately and explaining what happened. His reaction was applauded by the community and played a great role in reducing the reputation damage to Poloniex.

The exchange has email and SMS notification, but PGP encryption isn’t used in communication.

Poloniex Review Conclusion

Poloniex is an excellent exchange for all those looking to trade altcoins as well as Bitcoins.


  • Many altcoins to trade in
  • Margin trading in altcoins
  • Good liquidity


  • No fiat currency trading
  • Pumps and Dumps
  • Poor support

A great exchange with a good reputation.

    Has anyone filed complain to the related authority?

  2. Wilson, 6. August 2019

    After Circle took over, Poloniex stole 16.7% of our’s BTC and nothing paying us back after 2 months.

  3. Anna, 19. April 2019

    Hello! Now released a new token!
    More information here!

  4. saso, 14. November 2018

    Poloniex is a pure scam after they got bought by Circle, my story is that my login credentials were changed by them, and after i was unable to login i was forced to freeze my account, so the “hackers” wouldnt be able to compromise the funds in it. After that i opened 3 tickets to support and it was all about automatic responses and a prolonged silence after every email and ticket. So now im waiting someone from the Poloniex Team to respond to my fourth ticket about unfreezing and unblocking my account and removing the 2fa option from the login sequence, they stole from me 5000 usd worth of bitcoin and other cryptocurrencies. Its now 4 days with no answer and im wondering if there will ever be any. Im sure its inside job so thats how they are stealing money from ordinary ppl, just by freezing or blocking their accounts, and not responding to the ticketc afterwards, hoping that you are going out of hope and stop opening tickets, Poloniex is pure scam, it was a nice exchange, keep your money out of any centralised exchange, and you will be fine, i have learned my lesson…

    Please upvote for support. Let everyone know what Poloniex is! Thanks in advance!

    Good tidings, dear users. Many of you heard about one of the most active crypto exchanges in the world… Poloniex I mean. It is where my story begins…

    1) Poloniex doesn’t keep its promises!

    First of all, I’d like to provide you some information about me. I am a Poloniex user, a legacy one with two factor authentication enabled. On 27 May, two weeks before deadline my account had been frozen. It had been frozen in spite of a promise “Withdrawals will remain enabled at the daily withdrawal limits prior to the deadline”. I wish to point out that it was an official statement;

    2) Poloniex can keep your coins safe from you!

    When I knew my account had been frozen I had no choice. I had to be verified or leave them my coins. So I preferred to be verified. I’ve submitted them my government issued documents (there were no information that only international documents are acceptable) and the only adequate response was: ” The funds will be held safely in your account until the verification process is complete”. The thing is I told them that I cannot get international documents in near future and that I submitted my government issued ones. Now Poloniex is taking of my coins as hostages and urging me to be verified but don’t allow me to be verified with my own government issued passport! But Poloniex promises to keep our money safe! Poloniex keeps promises, isn’t it?

    3) Poloniex doesn’t adhere to its License Agreement in case of it relates to user rights!

    I’ve spent a lot of time to be verified and nobody ever wanted to help me. Only excuses and promises to keep my money safe. Afterwards I claimed to transfer my coins to my friend’s deposit adress. And there was reason to believe they would. There we are: In accordance with article 17 of the Terms of Use “You will be permitted to transfer Tokens associated with your Account for ninety (90) days after Account deactivation or cancellation unless such transfer is otherwise prohibited (i) under the law, or (ii) by a valid subpoena or court order.” I’ve created some more tickets and again no one is ever going to help. They tried to ignore my tickets first, then they started to close them as fast as they could and never ever answered me what is the reason they ignore the License Agreement when it relates to user rights!

    P.S. There were a lot of agents I have been talking to: Cole, Daniel, Dean, Edward, Fergus, Homer, Laura, Michelle, Rivero, Sandy etc. There might be someone who’d like to help but anyway I didn’t get help so far. Be careful with Poloniex, you wouldn’t like it kept your coins safe.

  6. Gintaras, 1. June 2018

    Am January 15, 2018, I made a currency withdrawal from exchange – 20000 DGB (Digibytes) . An entry in the Poloniex Financial Statement – Complete . However, digital assets do not reach the goal. The cryptocurrency is not transferred . TxID doesn’t show on blockchain . In that way, my currency was taken over . Ticket #712795 is still not resolved . Poloniex support is not working (the problem not resolving ). The new owner “Circle” refers to a poloniex support that does not work . The core of poloniex business is deception of customers . POLONIEX – CRIME organization . https://imgur.com/a/UTi4M85

  7. Ionut, 27. March 2018

    Definetly a big big scam. Fortunately they stole from me just 12 euros. It was the test money so indeed was a test they did not passed

  8. Jim, 14. March 2018

    I have been trying to get verified for over a month.
    Suddenly, they locked my account for no reason.
    I filed a complain here –>> https://www.consumer.ftc.gov/media/video-0054-how-file-complaint
    I received a response, next day!

  9. Anonymous, 12. March 2018

    I made the mistake of not doing my due diligence on poloniex. I signed up using their exhaustive verification process and never received any confirmations after submitting quite personal information. I also subsequently submitted support ticket regarding the matter with no response as well. Hopefully the information disappeared into the ether, but I remain very suspicious.

  10. P Potocsnak, 16. January 2018

    I have been trying to get verified for over a month. Coinbase verified me within a day.

  11. Shyam, 6. January 2018

    Lost my coin during withdrawals even if the transaction is complete and address is correct. Do not trade on it because during withdrawal they have this huge technical error or fraud website. Support not responding.

  12. mark, 23. December 2017

    Just rubbish support. They do not reply for tickets. Complete ignorance of the customers. they stole my 1.45 bitcoin and I have this feeling their are exit scamming

  13. Jamie, 18. December 2017

    Has anyone but me had their BTC stolen while using Poloniex and then got no response when desperate for help? It took them 4 months to respond to me and the only reason they did is because I was able to locate the attorney that represents Poloniex. Of course I was told it was my fault and that they were not responsible. They even went so far as to blame me for logging into a fake Poloniex website. This is unbelievable! I am going to offer this information on as many forums that I can involving Poloniex and based on your responses I am considering a class action lawsuit. It’s not so easy to sweep a group of people under the rug as it one person. I am prepared to offer up Poloniex attorney information. Just trying to determine my next steps.J

  14. John S Lauter, 15. December 2017

    There is Absolutely NO…NONE! Support, I have had a ticket pending for over a week and have sent several emails with nothing in return. I am moving everything out of this exchange. STAY AWAY FROM THEM.

  15. Scott, 26. November 2017

    So , after three months on a ticket Polo told me my account was hacked and coins stolen. They claimed that my email was also hacked. The account hacking, email hacking and sending of my coins all took place within min of me selling my BCN at a work computer . Either polo or my employer stole my coins. The “hack” happened when Polo disabled everyone’s accounts if they did not have two factor . I was told that the hackers also were able to click on the remove funds link though
    polo was blocked on my email & that had not been changed sine May . The supposed hack occurred in August. I think they sent all the customers coins that did not enable 2 factor to an outside BTC address & the back to the companies wallet. It was then blamed on a “hack”. When I traced the transaction ID several times the coins all went back to POLO?!!

  16. Wasim Khan, 7. November 2017

    my poloniex account was hacked 43 days ago(25th September 2017), I request to lock it because hacker try to withdraw my BTC but failed due to timely action of me to freeze my account, I reported everything on poloniex support but their support is too much poor that my account is still locked and they just reply me 2 times with general words that “we are looking into matter”. What the hell is that support. can any body help me in this case?

  17. DZHEYHUN YOZDZHAN, 6. November 2017

    Such a Rogue web Site. I wait almost 3 moths for the verification. Everybody wait over 2 moths. There is no support center. Nobody cares the customers. Just Stay away from POLONIEX… There is so many alternative like Bittrex, Kraken vs…

  18. Ahmad izham, 25. September 2017

    I hv review some of the comment below that saying poloniex it is really scammer platform to trade the btcoin.. it is true..

  19. keefer, 9. September 2017

    How much were you paid for this review?

    Go to CryptoCompare.. I am not alone when I say they are most likely a scam.. people are losing their money with them.. their security has issues, their customer support is none existent. I’ve been waing 2 weeks for help. I’ve seen some on CrytoCompare waiting some 45 days plus for a response fron the so called company. They don’t respond to emails They have NO PHONE NUMBER to contact them.. Once they have your funds they are keeping them..

    use another exchange

  20. Paras, 23. August 2017

    Ticket number #366765 poloniex is such a fraud my account is not working from the last 18 days and from since then I am not able to receive any response from their side. They are scam. I request all to transfer all their money from poloniex to any other crypto currency sites as soon as possible to save your money. Looking forward for the support from poloniex.

  21. Kteanboon, 22. August 2017

    Polo team is robber.

  22. ycl, 16. August 2017

    I have sent 1241.209187 XEM 2 days ago but it didnt show up in my account.
    This is the txid: 2a7b4c0427a54803bcb5e0545eef2e065335cc534643ac27a2dbc3725bb23df0
    I opened ticket two days ago but still they didnt reply. For a financial service platform this much delay is unacceptable. Its obvious they are scam. Forums are full of complains. Stay away from them. We must find a way to file them to SEC and let those guys arrested!

  23. Jason, 15. August 2017

    If at all possible I would give this company “0” stars. So my first experience with Poloniex started off great. Then I began to have deposit issues. I’ve put in tickets and have yet to get a response after weeks. Their support center is mostly non existent. Ultimately, my effective balance is zero and will most likely lose or never get my deposits. As a general rule of thumb, I don’t do business with companies out of California. This will be third and final company out of California to rip me off from my hard earned money. I recommend that you do not use this site for anything. They will lure you in with the best prices on currencies and slowly rip you off and there will be nothing you can do about it because of their new user agreement. Get your currencies away from these people and stay as far away from them as possible!

  24. bwkim, 12. August 2017

    They are lying.

    Monitoring around the clock.
    Our auditing programs monitor exchange activity 24/7/365. Their job is to report and block any suspicious activity before it becomes a problem.

    Is it true?

    I lost a lot of coins because they did not unfreeze my account.
    They are still not unfreeze my account and unresponse my ticket.
    Now, I lost almost 50 bitcoin.

  25. Lilly, 10. August 2017

    I just started using poloniex for a week. My coins disappear today and I couldn’t contract customer support. Horrible website, don’t use it.

  26. John, 9. August 2017

    Awful awful awful. Firstly 2F authenticator wont work, then I’m frozen out and now no response to support tickets. It seems they are now expecting a “run” on them with so much bad comment and cant open for fear of this. They are very bad news.

  27. kljsdghfhlukdswg, 1. August 2017

    New terms of service just came in, just one trade or withdrawal or deposit will result in accepting their terms of service, (taken from new Terms Of Service)

    You have no rights, they dictate all, HEIL POLONIEX!

    You can deposit, you cant withdrawal, and now you cant do anything about it…?!

    Do you really want to trade there?

  28. Robert, 28. July 2017

    Here’s the update, after 14 days Poloniex has finally resolved my issue and transferred my .256 BTC into my Coinbase acct. Will I ever trade again on Poloniex, probably not, until I see a tremendous improvement in customer service support tickets. I hope the best for you who still have issues with support tickets on Poloniex. Got lucky.

  29. Sezo, 27. July 2017

    I had a Support Ticked on Poloneix and 24 hours passed still no aswer yet.
    7 days passed PASC deposit but not in Balance yet. Evet it is shown in the History list.

  30. angry_man, 25. July 2017

    Worst support ever (maybe comparable with Yobit exchange, they are at least responding). Deposit easily made within 2hrs, withdrawal not processed even after 7 days. No response from support, total ignorance. Looks like a exit scam.

  31. Wolfgang, 25. July 2017

    About the Tier Status:
    they do offer the tier fee schedule but in fact it lags behind for several days. For algotrading it means that hundreds of dollars in fees are charged EXTRA. See the discussion here e.g. https://www.reddit.com/r/PoloniexForum/comments/6jyxsa/poloniex_tier_status_does_not_update_causing_huge/

  32. Robert, 23. July 2017

    Well as I see in this post and from a whole bunch of other post forums, I am also now a victim of the Poloniex “awaiting approval” fiasco. I have moved coins many of times from Coinbase/GDAX to Poloniex and vise versa without any problems(ETH, BTC, and LTC). So on the 14th of July I moved .256 BTC from Poloniex to Coinbase. I got confirmation email to approve transaction , approved it, and the next thing I know “awaiting approval” shows up. I have level 2 verification on Poloniex. I waited 24 hours, submitted ticket(#319713), and was assigned to an agent (Javan). Well it stills shows being processed. Oh I forgot to add that I move “LTC” from Poloniex to Coinbase with no problem the next day. Since my frustration I have opened 3 other tickets, no reply, no agent assigned. Nothing!!! Just get the emails of tickets submitted. Just out of curiosity, on my last ticket that I submitted, I sent a ticket in to close my account. I’m at the point of chocking this up to “Lessons” learned. What’s funny is that they haven’t even responded to that one either, this was a chance just to take my money, no questions asked. So I leave it up to you, to decide what Poloniex is really up too. I will update post when and if this ever gets resolved.

  33. Myroslav, 22. July 2017

    they locked my account and not respoding on my request to unlock.
    No mobile or skype contact. They looks more like old cheting forex sites.
    Took real money and no cotact with them.
    I want to somehow call police, becuase they simply hold my money but not respoding on my mails!

    I have 10 Ether missing on Poloniex and it’s been 41 days since I opened my support ticket up and they have yet to respond to me after countless efforts to reach them. It’s a known issue with a Ether withdrawal software issue where the transaction shows as completed in Poloniex but the TXID never even shows on the Ethereum blockchain.

  36. Peter, 19. July 2017

    Just rubbish support. They do not reply for tickets for 30 days and more. Complete ignorance of the customers.

  37. james, 19. July 2017

    guys i think its worse then we thought , i found this article , the guy is saying they did the same thing with ethereum fork ; if you guys a a bit wise , youll understand that they are doing the same now with bitcoin, i suggest everyone to rush a complaint to the sec that they arrest these guys asap

    Maybe they are EXIT SCAMMING, because if they are not,
    they need to change their damn management.

  50. John, 24. June 2017

    Non existent support, ETH fake Transaction IDs so your money is gone effectively if you try to take it out of Poloniex. It has happened with SIA and other altcoins as well. Avoid with your life. Poloniex is a scam lately.
