What is probably happening
Most freezes are not accusations. They are automated compliance triggers, and the people who can unfreeze you are often not the people you are talking to.
The common causes, roughly in order of frequency:
- Automated transaction monitoring. A pattern matched a rule: an unusually large deposit, a rapid in-and-out, a transfer to or from an address the exchange's analytics flagged.
- Chain analytics exposure. Coins you received have a history the exchange's screening tool dislikes, sometimes several hops removed from anything you did.
- Expired or incomplete verification. Documents aged out, or a periodic review was triggered by account activity crossing a threshold.
- Sanctions or PEP screening. A name, address or IP matched a list, frequently a false positive on a common name.
- A law enforcement request or court order. Less common, and the exchange may be legally barred from telling you.
- A suspicious activity report has been filed. In many jurisdictions the exchange is prohibited by law from telling you this. That prohibition, often called tipping off, is why support sometimes goes silent for no visible reason.
If the freeze relates to a suspicious activity report, the law in most jurisdictions makes it a criminal offence for the exchange to disclose that. Silence is not necessarily obstruction. It may be the only lawful answer available to the person reading your ticket.
The first 48 hours
Do not create a second account
This is the single most damaging reaction, and it is common. Opening a new account, using a different name, or asking someone else to withdraw for you converts a compliance review into apparent evasion. It can turn a temporary hold into a permanent closure, and in some jurisdictions into a criminal matter.
Preserve everything, immediately
Screenshot the account state, the balance, every message, every error, with dates visible. Download your full transaction history and any statements while you still have access, because access can narrow further.
Save it outside the platform. If the account is later closed, you may lose the ability to retrieve any of it.
Write everything down, in one file
Start a chronology: date, time, what happened, who you spoke to, ticket numbers. This feels excessive on day one and becomes the most valuable document you have by week six, especially if you escalate to a regulator or an ombudsman.
Use official channels only
The in-app ticket system or the published support address. Nothing else.
Do not post the problem publicly and then respond to anyone who direct-messages you. Fake support accounts monitor complaints on X, Reddit and Telegram continuously. Every one of them is a theft attempt, and people in exactly your situation are their target market.
Ask precise questions, in writing
Vague frustration produces vague replies. Ask specific things that create a record:
- Is this a temporary restriction or a permanent closure?
- What specific documents or information do you require from me?
- What is the expected timeframe for review?
- Which parts of my account are restricted: withdrawals, trading, deposits, all?
- Is there anything I can do to progress this?
Keep it factual and unemotional. Your correspondence may be read later by a regulator, a lawyer, or a court, and a calm, specific record is worth a great deal.
Answer what they ask, no more
If they request source of funds documentation, provide exactly that. Do not volunteer unrelated history, do not explain your whole financial life, do not speculate about what triggered the freeze.
Give complete, accurate answers to the questions asked. Nothing beyond them.
Source of funds requests
This is the most common resolution path, and it is where most people stall.
The exchange is asking you to evidence, on paper, where the money came from. Not to explain it. To show it. A narrative without documents is usually rejected.
What generally works: bank statements showing the transfer out, payslips, an employment contract, a sale contract, tax returns, an inheritance or gift document, an invoice, a signed statement from the payer.
What generally does not: screenshots without context, an explanation with nothing attached, or documents in a language they cannot read with no translation.
If the funds are old Bitcoin acquired years ago with poor records, say so plainly and provide what you have, including on-chain evidence such as the original receiving transaction. Honest incompleteness handles better than a story that does not match the documents.
Do not fabricate, backdate or edit a document to close a gap. It converts a civil compliance problem into fraud, and it is usually detected because the compliance team checks documents against each other for exactly this.
If it does not resolve
Escalate inside the exchange
Ask for the complaint or escalation procedure by name. Most regulated platforms have a formal complaints process, distinct from support, with defined response times. Ask for it in writing and request a final response.
Find out who regulates them
This determines every option you have. Look up the entity you actually contracted with, which is often not the brand name and often not in your country. Check the terms of service and the website footer for the licensed entity.
Once you know the entity, you know the regulator, the ombudsman scheme if any, and the governing law and forum in your contract.
Complain to the regulator or ombudsman
Many jurisdictions have a financial ombudsman or a regulator that accepts consumer complaints. Whether crypto platforms fall inside those schemes varies significantly and is changing, so check rather than assume. Most require you to have exhausted the firm's own complaints process first, which is why step one matters.
Consider data protection rights
If you are in the EU, the UK, or another jurisdiction with comparable law, you may have a right to request a copy of the personal data the firm holds about you. This sometimes reveals what triggered the review.
Expect limits. Firms routinely withhold material relating to suspicious activity reporting and crime prevention, and those exemptions are real rather than obstruction. But the request costs little and occasionally produces a great deal.
Get a lawyer, at the right point
Worth doing when the amount is material, when the freeze passes a few months, when law enforcement is mentioned, or when you are asked questions that feel like an investigation rather than a form.
A letter from a lawyer to the right department often moves a file that support tickets could not. Choose someone who does financial services or regulatory work, not a general litigator.
What to expect on timing
Simple verification issues clear in days. Source of funds reviews commonly take weeks. Cases touching sanctions screening or law enforcement can run for months with little communication, and the exchange may not be permitted to explain why.
Silence is not usually a sign that you have been forgotten. It is often a sign that the answer is legally unavailable.
Afterwards
Whatever the outcome, two things are worth doing.
Get your assets off the platform once access is restored, or at least reduce what you leave there. An exchange balance is a claim against a company, subject to that company's compliance decisions. Self-custody is not.
Build the file you did not have. Keep records of how you acquired everything, from now on. The next request will be easier if the documents already exist. This is the whole point of the source of funds file.
Everything here is written to stay true. It explains how the machinery works rather than what today's numbers are, because thresholds, rates and deadlines change every year and a stale legal page is worse than no page at all. Where a current figure matters to your decision, this page tells you how to find it rather than guessing on your behalf.
General information, not legal advice. This site does not provide legal advice, and no professional or advisory relationship is created. Consumer protection, complaints procedures, ombudsman access, data protection rights and the legal treatment of crypto platforms vary substantially between jurisdictions and are changing rapidly. Your specific rights depend on where you live, where the platform's operating entity is established, and the terms you agreed to. Consult a qualified lawyer licensed where you live before taking action on a material sum.
