My crypto exchange has blocked my withdrawal: what now?

Short answer

Check whether the exchange is genuinely regulated. A real exchange may hold a withdrawal for identity or source-of-funds checks but never asks for a payment to release funds. If you are asked to pay first, treat it as fraud: stop paying, report to your bank and Action Fraud, and keep every transaction hash.

A blocked withdrawal can mean two very different things: a genuine compliance check at a real exchange, or a fake platform that never intended to pay out. The first step is working out which one you are dealing with.

Written and reviewed by the Wallsec investigations team · Last updated

Signs it is a genuine compliance check

  • The exchange is registered with the FCA or a comparable regulator and you can verify that independently.
  • Requests come through the official app or website, not by private message.
  • They ask for identity or source-of-funds documents, never for a payment to release funds.

Signs it is a fake platform

  • You are asked to pay a fee, tax or deposit before withdrawing.
  • Support is only reachable by chat app or a personal contact.
  • The website was registered recently or does not appear on any regulator's register.

What to do next

For a real exchange, respond only through official channels and keep a written record. For a suspected fake platform, stop payments, report to your bank and Action Fraud, and preserve every transaction hash so the deposits can be traced.

Common questions

How long can a real exchange hold my funds?
Review times vary. A regulated exchange should explain what it needs and give you a route to complain, including to the Financial Ombudsman where applicable.
Can the deposits to a fake platform be traced?
Often yes. Your deposits are recorded on the public ledger and can be followed to see where they were moved.
