When an exchange will not release your money

Your exchange balance is not your coins. It is a claim on a company: the exchange owes you the amount, the way a bank owes a deposit, and the coins behind that claim sit in wallets it controls. So the question splits in two. Can an exchange legally keep your money? In most jurisdictions no, and taking client assets is theft or fraud. Can it stop you withdrawing, lawfully, for weeks? Yes, and the terms of service say so in writing.

Six reasons a withdrawal stops

• Compliance review. A deposit that arrived from a service under scrutiny triggers a review of the account that received it, and the exchange asks where the money came from.
• Sanctions screening. A counterparty on a government list freezes transfers involving it, addresses included, and the user whose deposit passed through gets caught by association.
• Suspected account takeover. A password reset, a new device, a changed address and a sudden full-balance request look the same whether the owner or a thief is behind them.
• Technical work. Hot wallet maintenance, a chain halt, an upgrade. Hours, everybody at once, usually a posted notice.
• Expired verification. Rules change and documents lapse, so accounts that passed checks years ago are asked again.
• Solvency. The exchange does not have the coins. Rare, and the one case where waiting does not help.

How to tell which one you are in

Start with scope. If the status page shows an incident and others report the same thing, the problem is technical. If withdrawals work for everybody but you, the hold is on your account. Ask for the reason in writing, because a compliance hold has a procedure and support can usually name the stage. An exchange is often permitted to say that it stopped a transfer over a listed counterparty: the FinCEN proposal against the A7 Network lets institutions disclose exactly that. Then watch the chain, since exchange wallets are public. Large outflows to other customers while your request sits means the problem is yours alone. Wallets quiet across the board is the solvency case.

What to send, and in what order

Send one message with everything in it: account identifier, exact amount, withdrawal address, transaction hashes of the deposits in question, dates, and the origin of the funds with proof. Each time support has to ask for one more document the review restarts, so a single package is the fastest route. Put a deadline in the message, keep every reply, and if the exchange holds a licence name the regulator in your second letter. A licensed company has a complaints procedure it must follow, and the reference moves a ticket out of the general queue.

When an exchange will not release funds, three reactions make it worse: opening a second account to route the balance out, which reads as evasion; sending documents one at a time, which restarts the clock; and posting account details in a public chat, where the people hunting for exactly that are reading.

Before it happens

Before any of it happens, keep on the exchange only what you trade. Everything else belongs in a wallet whose keys you hold, the one arrangement where no company can delay you, though self-custody moves the whole risk of losing those keys onto you. Products that split the difference deserve a close reading: the Binance.US wallet divides its key three ways and the exchange keeps one share. Keep order numbers, receipts and transaction hashes from day one, because compliance asks for documents that are hard to obtain six months later.

An exchange can stop a withdrawal lawfully and explain little. It cannot keep the money, and most holds end with release once the paperwork clears. The cases that end differently show up in the chain data and the withdrawal queue before they show up in support replies.

Informational material, not legal or investment advice. Procedures differ by exchange and jurisdiction, and a specific case is read against the terms of service that apply to it.
