Introduction: An Exchange Where “The Bots Are Great, But Withdrawals Are a Nightmare”
In the first 32 installments, we dug into a wide range of exchanges, from HashKey to Ourbit. For the 33rd edition, were looking at one with perhaps the biggest split personality of them all — Pionex.
On the “product innovation” side, Pionex certainly has an impressive résumé: “incubated by BitUniverse in 2019,” backed by Gaorong Capital, Shunwei Capital, and ZhenFund, 16 free built-in trading bots, more than $60 billion in monthly trading volume, over 5 million users worldwide, a CoinGecko Trust Score of 8/10, monthly Proof of Reserves, a BTC reserve ratio of 142%, and U.S. FinCEN MSB registration.
Sounds like one of the stars of the automated trading sector, right？
But on the other side of the story, FX110 users have complained that “380,000 USDT has been frozen for a year and a half, while the platform requires a certificate from the Bangladeshi police — even though crypto trading is illegal locally, making it practically impossible for the police to cooperate.”
Pionex also has a 2.5/5 rating on Trustpilot, classified as “Poor,” with one user claiming that a $1,002 deposit was “indefinitely withheld as compensation for damages.” BrokerDefense has described it as an exchange “with no company name, no address, and no regulation.” WikiBits rating warns: “No valid crypto-asset regulation is currently available. Please be aware of the risks.” In July 2026, HTX reported that dismissed employees had threatened retaliation, while the company proposed “installment compensation terms.”
So how can an exchange with such polished trading bots and seemingly strong financing credentials leave users waiting a year and a half to withdraw their funds？
Lets dig into it layer by layer.
1. Regulatory Compliance: Authorization and Compliance Issues Exist Across Multiple Jurisdictions
First, one of the easiest things to misunderstand: Pionex is not completely unregulated. However, Pionex Global and Pionex.US must be evaluated separately.
Pionex.US: A Relatively More Complete U.S. Regulatory Framework
Pionex.US is a separate U.S. entity. Publicly available information identifies Pionex Inc. as its U.S. operating entity.
Since 2022, Pionex.US has disclosed information regarding a number of U.S. state-level Money Transmitter licenses and approvals.
Pionexs historical Proof of Reserves materials have also explicitly treated Pionex.com and Pionex.us as two separate platforms.
This distinction is extremely important: Pionex.USs U.S. licenses do not mean that the Pionex Global platform enjoys the same regulatory coverage.
Frances AMF Has Explicitly Flagged Pionex.com
On April 10, 2025, the French Financial Markets Authority (AMF) officially added www.pionex.com to its blacklist of crypto-asset websites.
The AMFs stated reason was that the website was providing financial services or products without authorization.
Then, in July 2025, the AMF issued another notice listing www.pionex.com among newly added unauthorized crypto-asset service websites.
For French users, this means that Pionex Global is subject to an explicit regulatory warning.
This is not simply a claim made by an individual user saying that Pionex is non-compliant. It is a publicly published list issued by Frances official financial regulator.
No Evidence Found That Pionex Itself Is on the U.S. OFAC SDN List
Based on the public information reviewed for this report, we did not find sufficient evidence showing that Pionex itself has been designated by the U.S. Office of Foreign Assets Control (OFAC) on its Specially Designated Nationals (SDN) list.
This is a different matter from the French AMF blacklist and any U.S. state-level regulatory consent orders.
Therefore, the more accurate regulatory picture of Pionex at present is:
Pionex faces authorization and compliance issues in multiple jurisdictions, but there is no evidence that Pionex itself has been designated as an OFAC-sanctioned entity.
Another point deserves attention: the offshore global entity used by the vast majority of Chinese-speaking users does not hold a comprehensive crypto-exchange license in major jurisdictions such as Singapore or Hong Kong. Any MSB registrations held by specific subsidiaries do not automatically cover users in every jurisdiction.
Many users mistakenly assume that holding one license means that all accounts worldwide are equally protected. That is a major misconception.
Risk Rating: Medium-High
2. Account Security and Withdrawals: 380,000 USDT Frozen for 18 Months, With an “Impossible-to-Fulfill” Unfreeze Requirement
Small withdrawals generally go through smoothly, but complaints involving risk-control freezes do exist. Quantitative trading bots can also create a form of “false asset lock,” while on-chain tracing has its own barriers.
Pionex has a relatively complete set of account-security tools, including Google two-factor authentication, withdrawal whitelists, and anti-phishing codes. The platform experienced a security incident in 2022 and subsequently compensated affected users. Its basic security infrastructure is therefore relatively complete.
However, because Pionex focuses heavily on quantitative trading bots, many beginners cannot distinguish between “funds occupied by a bot” and “funds frozen by platform risk controls.” As a result, complaints can easily become mixed together.
Real User Feedback
Case 1: Funds “frozen” because trading bots are still running
A large number of novice users have complained that their account assets were frozen. In many cases, however, the assets were actually being used by Grid, Martingale, or TWAP bots. Once the bots were stopped, the funds were immediately released.
This is essentially a false freeze caused by the product mechanism, rather than an indication that the platform is deliberately withholding funds. It is also one of the most common types of complaints in the Pionex complaint section.
Case 2: Large withdrawals trigger AML reviews
For users making ordinary transactions, small withdrawals can generally be completed on time. However, some users making large withdrawals have triggered AML reviews and been asked to provide additional proof of the source of funds.
After submitting the required documents, some users reported that the review process was significantly prolonged, during which their withdrawal functions were restricted. The WikiBit complaint database contains several reports in which users said that their submissions had remained under review for weeks without a result.
Case 3: Funds deposited through OTC channels trigger risk controls
A small number of users have reported that assets deposited through over-the-counter channels triggered risk controls because of risks associated with upstream wallet addresses.
In such cases, the platform allegedly restricted the accounts entire withdrawal function. Customer service reportedly only informed users that their accounts had triggered AML rules, without providing complete evidence concerning the allegedly risky on-chain addresses. This makes it difficult for users to prove the legitimacy of their funds.
Case 4: Fiat-transfer refunds resulting in funds being stuck
Some users have reported that after a fiat-channel transfer was returned, their funds became stuck within the payment channel. In one case, the platform reportedly took two months to determine where the funds had gone, leading to criticism over the efficiency of its asset-recovery process.
Current Status of On-Chain Wallet Tracking
Pionex publicly discloses cold-wallet and hot-wallet addresses and provides Proof of Reserves information. Ordinary users can use the platforms official tools to verify whether their assets are included in their respective Merkle Tree snapshots.
However, third-party platforms such as FX110, WikiBit, and Trustpilot show that many negative reviews are concentrated around withdrawals and account freezes.
The 380,000 USDT Case: A Withdrawal Dispute That Lasted 18 Months
“380,000 USDT frozen, with the platform demanding a certificate from the Bangladeshi police” is arguably one of the most bizarre withdrawal cases in this entire series.
On July 10, 2026, a user filed a complaint with FX110 involving approximately $380,000 in disputed funds.
According to the complaint:
“In January 2025, my partner deposited 3.8 BTC into a Pionex account and normally converted it into USDT on the platform. The KYC-verified account holder was my partners mother, who is a Bangladeshi national. One day after the deposit and conversion were completed, an attempt was made to withdraw part of the funds, after which the account was subjected to risk-control restrictions.”
The user claimed that the dispute then entered 18 months of repeated negotiations:
“During this period, we repeatedly submitted proof of the source of funds, KYC video verification, an exemption video, the source wallet used for the deposit, commercial cooperation contracts, and various other documents as requested by the platform. Communication continued until December 2025, when the platform introduced an additional and extremely stringent requirement: all documents had to be certified by the local police in Bangladesh, and the police had to proactively contact Pionex to verify the authenticity of the materials.”
According to the complaint, the user subsequently consulted local lawyers and law-enforcement agencies in Bangladesh and was told three key things:
Local police have no obligation to cooperate with overseas cryptocurrency exchanges in conducting investigations.
Cryptocurrency-related activities fall into an illegal category in Bangladesh and are not protected under local law.
Local police have neither the authority nor the obligation to issue certificates concerning the source of an individuals assets.
Put simply:
Pionex asks you to provide a certificate from the Bangladeshi police → Bangladeshi authorities say, “Cryptocurrency trading is illegal here, and we will not cooperate” → Pionex says, “Then youll have to keep waiting” → 18 months later, the 380,000 USDT is still stuck at Pionex.
FX110s response was blunt:
“Pionex is an unregulated cryptocurrency investment platform with a very high level of risk. Stay away!”
The $1,002 “Damages” Case
A Trustpilot user described an even more unusual experience:
“My account was frozen due to allegations of abuse of a futures grid bonus promotion. Pionex did not accuse me of any illegal activity, fraud, or prohibited source of funds. I provided complete documentation proving the legitimate source of my deposit. Despite this, Pionex informed me that my entire deposit principal ($1,002) would be withheld indefinitely as ‘damages.’”
The user continued:
“I formally requested that Pionex explain or quantify the alleged damages and explain how my deposit constituted compensation for those damages. No calculation, evidence, or proportionality explanation was provided. Pionex subsequently stopped responding.”
In other words:
$1,002 was withheld on the grounds of “damages,” yet the platform allegedly did not explain what the damages were, how much they amounted to, or how the $1,002 figure was calculated.
The situation bears similarities to complaints involving other exchanges where users have alleged retrospective deductions from profits.
Chrome Web Store reviews have also repeatedly mentioned issues such as:
“Withdrawals being blocked or funds being frozen for extended periods.”
“They want to hold my funds for 60 days.”
Risk Rating: High Risk
3. Proof of Reserves Transparency: The PoR Looks Good, But “Looks Good” and “Can You Withdraw？” Are Two Different Questions
PoR Data: 142% BTC Reserve Ratio
Pionex has indeed made substantial efforts to improve transparency around its reserves.
According to a report by TradersUnion, Pionexs September 2026 Proof of Reserves report showed:
BTC reserve ratio: 142%
ETH reserve ratio: 135%
USD reserve ratio: 140%
All of these reserve ratios were above users total balances.
Pionex uses a combination of Merkle Tree verification and independent auditing to demonstrate that its reserves cover user liabilities. Users can calculate a hash using their user ID, asset type, and balance, and use the platforms open-source code to independently verify whether their assets are included in the Merkle Tree.
But where is the problem？
First: Who Is the “Independent Auditor”？
Who exactly is the independent auditing firm？
Pionexs Help Center has referred to having “engaged an independent auditing firm” and stated that the report would be released several weeks later. However, no specific auditor name or complete audit report has been clearly disclosed in the materials reviewed.
Bitvavo identifies The Network Firm LLP. Coincheck has used a major accounting firm.
So the question remains:
Who exactly is Pionexs “independent auditor”？
Second: A 142% Reserve Ratio and 380,000 USDT Frozen for 18 Months Are Not Mutually Exclusive
These two facts can exist at the same time.
An exchange can theoretically have a 142% Proof of Reserves ratio while some users are unable to withdraw their funds.
Why？
Because PoR primarily demonstrates asset coverage, not the platform‘s willingness or ability to process a particular user’s withdrawal.
In simple terms:
PoR tells you how much money the platform claims to have. It does not, by itself, tell you whether you can withdraw your money today.
Third: A Snapshot Is Not a Continuous Guarantee
An audit or Proof of Reserves snapshot only demonstrates that sufficient assets were present at a particular point in time.
It does not necessarily prove that the platform did not move or otherwise use assets between snapshots. Nor does it guarantee that the platform can withstand a sudden liquidity run.
Therefore:
Proof of Reserves is a meaningful positive factor, but it is not the same thing as an insurance policy or an absolute guarantee of withdrawals.
Risk Rating: Medium-High
4. Financial Strength: An Established Mid-Sized Exchange With Early VC Backing, but No Top-Tier Institutional Backer
Pionex launched in 2019 and has millions of registered users worldwide. It focuses heavily on quantitative trading and offers a relatively complete product lineup, including spot trading, futures, financial products, and crypto card services. Third-party on-chain data indicates that its cold-wallet holdings place it within the mid-sized exchange tier.
Strengths
Pionex has been operating for seven years and has survived multiple bull and bear market cycles. Following historical security incidents, the platform compensated affected users. It also has no known history of a mass exit scam or collective disappearance with user funds.
Key Weaknesses
Pionex received VC investment in its early stages, but it was not backed by top-tier institutions in the same way as exchanges such as Binance or Coinbase. It therefore lacks the kind of heavyweight institutional backing that could provide an additional layer of confidence.
A portion of the platform‘s reported trading volume may involve liquidity aggregated from external exchanges. Therefore, publicly reported trading volume does not necessarily equal the volume generated by Pionex’s own active user base.
Pionex has not publicly disclosed a massive independent risk-insurance fund. In the event of an extremely large-scale hack, compensation would therefore primarily depend on the platforms own reserves.
As a mid-sized exchange that has survived multiple market cycles, Pionex has demonstrated a certain degree of resilience, but its capital base does not appear comparable to that of the largest tier-one exchanges.
Risk Rating: Medium Risk
5. Internal Operations and Team: Daniel Yeo + Guojing Tang — But Who Is “Chen Yong”？
Founders: Daniel Seng-Cheng Yeo and Guojing Tang
Tracxn identifies Daniel Seng-Cheng Yeo and Guojing Tang as Pionexs founders, with both listed as CEOs.
Daniel Yeo has been described as a “technology entrepreneur” based in Singapore. Pionex was incubated by BitUniverse, which was founded in 2018 and described as the worlds third-largest crypto asset management application.
But where are the questions？
First: Limited Public Information About the Founders
Apart from records on Tracxn and Coinpedia, there is relatively little detailed public information about Daniel Yeo and Guojing Tang, including limited LinkedIn profiles, conference appearances, or in-depth media interviews.
Second: BitUniverse Is Associated With “Chen Yong”
Multiple sources identify Chen Yong (Yong Chen) as the CEO of BitUniverse.
Chen Yong has extensive experience in the technology industry, including serving as a vice president at Kingsoft Network and as a co-founder of Cheetah Mobile.
But what exactly is Chen Yongs relationship with Pionex？
Publicly available information does not clearly explain this relationship.
Third: Who Else Is on the Team？
Beyond the two founders, Pionexs core management team is barely visible in the public domain.
BrokerDefense has characterized the exchange as having “no face” — essentially questioning how an exchange claiming millions of users can have so little publicly verifiable information about its leadership and core team.
Fourth: The July 2026 Layoff Controversy
In July 2026, HTX community reports cited Pionexs official Twitter account as saying that there was no bankruptcy or liquidity shortage, while dismissed employees allegedly believed the compensation offered was inadequate and made retaliatory threats during the restructuring discussions. The company subsequently proposed installment-based compensation terms.
An exchange claiming 5 million users and more than $60 billion in monthly trading volume having to use installment-based compensation arrangements to address a staff layoff dispute naturally raises questions about its internal operations.
Risk Rating: Medium Risk
6. Product Experience and Trading Depth: The Bots Are the Selling Point, but Withdrawals Are the Core Issue
Product Lineup
Pionexs core competitive advantage is its 16 free built-in trading bots, including Grid Trading, Martingale, Dollar-Cost Averaging, and other automated strategies.
The platform supports more than 300 trading pairs and also offers leveraged trading. Its App Store and Google Play ratings are relatively decent, while Trustpilot contains numerous positive reviews praising its trading bots and responsive customer service.
But the Pain Points Are Potentially Serious
First, withdrawals are the biggest problem.
“380,000 USDT frozen for 18 months,” “$1,002 withheld as ‘damages,’” and “withdrawals frozen for 60 days” are all potentially serious issues from a user-funds perspective.
Second, customer service appears to respond selectively.
Trustpilot indicates that Pionex has responded to 92% of negative reviews. However, the user whose $1,002 was allegedly withheld claimed:
“After formally requesting an explanation, Pionex stopped responding and did not reply for more than 30 business days.”
Third, even the best trading bot is of limited value if you cannot withdraw your money.
An exchange that allegedly leaves 380,000 USDT frozen for 18 months can have 16 excellent trading bots, but those bots may simply help you generate numbers inside your account rather than help you take your money out of the account.
Risk Rating: Medium Risk
7. Real Community Feedback: 2.5/5, With “Unregulated” Complaints Repeatedly Appearing
Rating Distribution
Trustpilot: 2.5/5 — “Poor”
WikiBit: “No valid crypto-asset regulation currently available”
Gridinsoft: 39/100 — “Suspicious Website”
FX110: “An unregulated cryptocurrency investment platform — stay away.”
Negative Reviews Are Concentrated Around the Critical Issue of Withdrawals
Users who have never experienced withdrawal problems tend to describe the platform as having useful trading bots, a smooth interface, and responsive customer service.
Users who have encountered withdrawal problems, however, report issues such as:
“380,000 USDT frozen for 18 months”
“$1,002 withheld as ‘damages’”
“Withdrawals frozen for 60 days”
“Customer service failed to respond for more than 30 days”
This creates a clear divide in the community feedback:
For users whose withdrawals work normally, Pionex may feel like a convenient quantitative-trading platform. For users whose accounts trigger risk controls, the experience can become dramatically different.
Risk Rating: High Risk
8. Overall Exit Risk Assessment
| Dimension | Risk Level | Summary |
| Regulatory Compliance | High | Blacklisted by France‘s AMF; WikiBit, FXVerify, BrokerDefense, Gridinsoft, and FX110 characterize it as “unregulated” |
| Account Security / Withdrawals | High | “380,000 USDT frozen for 18 months”; “$1,002 withheld as ’damages”; “withdrawals frozen for 60 days” |
| Reserve Transparency | Medium-High | 142% BTC PoR + Merkle Tree + user self-verification, but who exactly is the “independent auditor”？ |
| Financial Strength | Medium | 5 million users and $60 billion in monthly trading volume, but Tracxn indicates “zero funding” |
| Team & Operations | Medium | Founders Daniel Yeo and Guojing Tang, but limited public information; 2026 layoff controversy |
| Product Experience | Medium | 16 trading bots are a major selling point, but withdrawals remain the “paper feature” |
| Community Feedback | High | Trustpilot 2.5/5; FX110 says “unregulated — stay away”; Gridinsoft 39/100, “suspicious” |
Overall Rating: High Exit Risk
Pionex is an extremely unusual case in this series — a contradiction between an “innovative product pioneer” and a “withdrawal nightmare.”
Its key risk characteristics include:
1. Extremely Conflicting Regulatory Assessments
TradersUnion gives Pionex a “Tier-1” rating of 9.8/10, while WikiBit, FXVerify, BrokerDefense, Gridinsoft, and FX110 all characterize it as “unregulated.”
Five platforms saying “unregulated” versus one saying “Tier-1” — which side should users believe？
BrokerDefenses characterization of Pionex as having “no face, no address, and no regulation” is particularly striking.
2. An “Unfulfillable Local-Jurisdiction” Unfreeze Requirement
The 380,000 USDT case reportedly remained frozen for 18 months, with the platform requiring documentation from Bangladeshi police.
But if the users account is subject to local legal restrictions around cryptocurrency activity and local authorities are unwilling or unable to cooperate, the requirement becomes extremely difficult to fulfill.
This goes beyond an ordinary AML review from the users perspective: the concern is whether the conditions imposed by the platform can realistically be satisfied at all.
3. Attractive PoR Does Not Automatically Mean Withdrawals Are Available
A 142% BTC reserve ratio is certainly a notable figure.
But it does not automatically answer the question of whether an individual user can withdraw funds when their account is under review.
The user whose 380,000 USDT was reportedly frozen for 18 months could, in principle, still exist within a system showing a 142% overall reserve ratio.
That is the fundamental distinction:
Proof of Reserves measures asset coverage. It does not guarantee frictionless withdrawals for every user.
4. A “Half-Hidden” Management Team
Public information about founders Daniel Yeo and Guojing Tang is relatively limited, while BrokerDefense has described the platform as having “no face.”
For an exchange claiming millions of users, the limited amount of independently verifiable information about its broader management team is worth noting.
5. The 2026 Layoff Controversy
The statement that there was “no bankruptcy or liquidity shortage”, together with reports concerning installment-based compensation, creates an apparent tension with the platforms narrative of 5 million users and $60 billion in monthly trading volume.
This does not by itself prove financial distress, but it is a factor worth monitoring.
Ultimately, this is not simply a question of whether Pionex has “high exit risk.”
It is the much more specific question of whether an exchange can simultaneously offer sophisticated automated trading products while some users report being unable to access substantial amounts of their own funds for extended periods.
9. Recommendations for New and Existing Users
For New Users
1. Enter cautiously.
Pionex is not a platform like UZX or Azbit that immediately appears obviously questionable. It has a CoinGecko Trust Score of 8/10, Proof of Reserves, and 16 built-in trading bots.
But the combination of the reported 380,000 USDT frozen for 18 months, multiple regulatory concerns, and an allegedly difficult-to-fulfill unfreeze requirement creates a risk profile that deserves serious consideration.
2. If you still decide to try it, test the entire process with a small amount first:
Deposit → Trade → Withdraw.
The withdrawal stage is particularly important. The user whose 380,000 USDT was reportedly frozen also initially encountered no obvious problem after depositing and converting the funds.
3. Be cautious about the narrative that “bots help you make money.”
A bot can generate profits inside an account.
That is not the same thing as being able to withdraw those profits.
For Existing Users
1. Review your current exposure.
If funds held on Pionex represent a significant portion of your overall assets, consider evaluating your ability to withdraw them rather than assuming that everything will remain accessible.
2. Test a withdrawal now.
If a withdrawal goes through normally, that provides some evidence that your account is currently functioning normally.
If it does not, discovering the problem earlier gives you more time to address it.
3. If withdrawals are blocked, do not blindly pay “unlocking” fees.
Be particularly cautious about requests involving:
“Risk-control review fees”
“KYC verification fees”
“Security deposits”
“Margin”
Other payments supposedly required to unlock withdrawals
Paying additional money does not automatically guarantee that the original funds will be released.
4. Preserve all evidence.
The 380,000 USDT complainant was reportedly able to document the dispute through extensive records, including support tickets, emails, source-of-funds documents, and transaction information.
If you encounter a withdrawal dispute, preserve:
Customer-service conversations
Emails
Deposit and withdrawal records
Blockchain transaction hashes
KYC documents submitted to the platform
Source-of-funds documentation
Screenshots of account restrictions and notices
5. Do not deposit additional funds simply because the platform says you need to do so before withdrawing.
This may be the simplest — and potentially most important — precaution.
Final Takeaway
Who is Pionex suitable for？
Users who understand automated trading strategies, are comfortable with the platform‘s regulatory uncertainties, and have not encountered withdrawal restrictions may find Pionex’s automated trading tools useful.
Who should exercise particular caution？
Users who place a high priority on withdrawal certainty, regulatory protection, and transparent corporate information should pay particular attention to the issues discussed above.
Pionex occupies a complicated position.
Compared with platforms such as UZX and Azbit that have attracted significant regulatory and operational concerns, Pionex has substantially more visible infrastructure: a CoinGecko Trust Score of 8/10, a reported 142% BTC reserve ratio, 16 built-in trading bots, and an incubation history linked to BitUniverse.
At the same time, compared with more heavily regulated exchanges such as HashKey and Bitvavo, Pionex faces a different set of challenges: multiple sources characterize its global platform as unregulated, a reported 380,000 USDT withdrawal dispute allegedly lasted 18 months, and BrokerDefense has criticized its lack of publicly verifiable corporate information.
The simplest way to describe the contradiction is this:
Pionex is like a highly intelligent automated trading assistant. It can help calculate an optimal trading strategy — but when you ask it, “Can you help me withdraw my money？” the answer, in the most extreme reported case, becomes: “Please get the Bangladeshi police to contact me first.”
