What Happens to Your Crypto When an Exchange Loses Its MiCA Authorisation

TL;DR:

When an exchange lacks, loses, or fails to obtain MiCA authorisation, the question may no longer be only whether users prefer to leave. It can become an orderly-exit process with a timeline. ESMA requires a crypto-asset service provider (CASP) that is not authorised to wind down its EU activities in an orderly way, which means the account is on a platform that can no longer serve EU clients normally, and as a client of an unauthorised provider you do not benefit from MiCA safeguards, including client-asset protections. There may also be a deadline after which the platform closes any remaining positions for you.

Three things are worth doing without delay: confirm your provider’s actual status in the official register, read your platform’s own wind-down notice for its timeline, and move your assets in good time. ESMA names two legitimate destinations, an authorised CASP or a self-hosted wallet. This reference is about handling a wind-down, not about weighing the choice in general. It is not investment, legal, or tax advice; for reporting obligations, see the DAC8 references.

First, confirm this is actually your situation

Not every EU exchange is in this position, so the first step is to find out which situation you are in. There are three.

Your provider is authorised. It obtained a MiCA licence and can keep serving EU clients. In that case you are not in a wind-down at all, and the relevant question for you is the ordinary one of whether to stay or move, which the reference on what MiCA changes about leaving a centralized exchange covers as a trade-off.

Your provider is winding down in an orderly way. It did not get authorised, and it is doing what ESMA expects: telling clients, limiting itself to letting you exit, and giving a timeline.

Your provider appears unauthorised, but it is not clearly communicating an orderly wind-down. It does not appear to be authorised, but its communication is unclear or it appears to be dragging. This is the situation that calls for the most caution.

To tell which one applies to you, check the official ESMA or national register for the specific legal entity that serves you, not the brand. A licence attaches to a particular authorised entity, so a familiar brand name does not guarantee that the entity holding your account is the authorised one. The next section explains what an orderly wind-down should look like, which helps you judge the second and third cases apart.

What ESMA requires a winding-down exchange to do

This is the part that tells you whether your platform is behaving as it should. In a public statement on 23 June 2026, as the MiCA transitional period reached its end, ESMA set out what an unauthorised CASP must do.

An unauthorised provider must stop taking on new EU clients, stop opening new accounts or client relationships, and stop marketing and solicitation. It must limit its services to what is necessary for an orderly exit, which ESMA describes as letting clients sell or transfer crypto-assets, reallocate assets, or close positions. Its custody of client crypto-assets can continue only for the period strictly necessary to complete that orderly exit, not indefinitely. And it must communicate clearly and repeatedly with clients about the timeline, including any deadline by which it would close remaining positions automatically.

Two practical readings follow from that. The first is a test for your own platform: if it is still marketing to EU clients, onboarding EU clients, or otherwise serving EU clients as normal while it is unauthorised, that is a mismatch with what ESMA expects, and a reason for more caution rather than less. The second is about time: custody is meant to last only as long as an orderly exit needs, and there may be an automatic-closure deadline, so the assets are not sitting there on an open-ended basis.

What protection you have while it winds down

It is worth being clear-eyed about this, because it is the reason not to leave assets on a winding-down platform longer than needed. MiCA’s client protections, including the client-asset safekeeping rules that require an authorised provider to protect ownership and separate client assets from its own, apply to clients of an authorised CASP. ESMA said directly that clients of unauthorised CASPs do not benefit from MiCA safeguards, including protections for client assets.

So the position during a wind-down is that your assets sit with a provider that is both winding down and outside MiCA’s protective perimeter. The reference on what MiCA changes about leaving a centralized exchange covers how those Article 70 client-asset protections work on the authorised side; the point here is narrower, that a winding-down unauthorised provider is not where those protections apply.

During a wind-down, your assets sit with a provider that is both winding down and outside MiCA’s protective perimeter.

Sorting what you are actually moving

Before you move anything, it helps to be clear about what you are moving, because an exchange bundled several different things into one account and they do not all “move” the same way.

Your held crypto is the straightforward part. Coins the platform was holding for you can be transferred out, either to another authorised provider (custody continues, with a different provider) or to a wallet you control (you take custody yourself). This is the part that leaves cleanly; which destination you choose is what decides whether a provider is still holding your assets afterward.

The platform’s trading service is not something you move. Buying and selling on the platform’s order book was a service it provided, and that service is what is ending. The equivalent from self-custody is swapping tokens on-chain yourself, which covers a similar need but works differently and carries its own routing and protocol risks. The reference on whether self-custody can replace a CEX covers that side.

The fiat on- and off-ramp needs a regulated route, but not necessarily this exchange. Converting between euros and crypto runs through a regulated provider, which can be a bank, an e-money or payment provider, or a licensed on- or off-ramp service, including one integrated into a self-custody wallet. Losing this exchange does not mean losing the ability to move between euros and crypto; it means using a different regulated route for that leg.

If you choose to hold the “held crypto” part yourself rather than move it to another provider, that is where a self-custody wallet comes in. A self-custody wallet such as DeGate is where you hold your own keys and sign transactions yourself, instead of relying on a provider to hold and act for you. The fiat leg and any regulated service still route through a regulated provider, as above; the wallet is only the part where you take custody into your own hands.

An orderly-exit checklist

If your provider is winding down, the useful checklist is about acting in good order, not about saving a few basis points on fees.

• Confirm the status yourself. Check the ESMA or national register for the legal entity serving you, and read your platform’s own wind-down notice for its stated timeline and any automatic-closure deadline.
• Confirm the destination. Know the exact legal entity and jurisdiction on the receiving side, whether that is another authorised provider or your own wallet.
• Where possible, test with a small amount first. Before moving a large balance, send a small test transfer to confirm the address, network, and destination behave as expected. Note that wind-down or withdrawal conditions may limit whether a small test is possible.
• Do not assume consolidating into one token is cheaper. Converting everything into a single token just to move it may add extra trades, spreads, network choices, and record-keeping complexity. Compare the actual route rather than assuming one-token consolidation is simplest.
• Keep your records. Retain transaction history and statements from the platform before access is wound down and the data becomes hard to retrieve.
• Remember that self-custody does not change your reporting obligations. Moving assets to your own wallet is a custody choice, not a substitute for checking your reporting obligations. For EU reporting, see the DAC8 references; this reference does not cover tax treatment.

FAQ

My exchange isn’t MiCA-authorised. Do I have to sell everything? No. An unauthorised provider winding down means you need to move or close your positions in an orderly way, but that does not require selling to cash. Depending on the asset, you may be able to transfer crypto-assets to an authorised provider or to a self-hosted wallet instead of selling. Check the platform’s wind-down notice for its specific timeline.

What is my exchange required to do while it winds down? Per ESMA’s 23 June 2026 statement, an unauthorised provider must stop onboarding new EU clients and stop marketing, limit itself to letting clients sell, transfer, reallocate, or close positions, keep custody only for as long as an orderly exit needs, and communicate the timeline, including any deadline for closing remaining positions automatically.

Is my crypto protected while my exchange winds down? MiCA’s client-asset protections apply to clients of an authorised provider. ESMA has said clients of unauthorised CASPs do not benefit from MiCA safeguards, including protections for client assets. That is the main reason not to leave assets on a winding-down platform longer than necessary.

Where can I move my assets? ESMA names two legitimate destinations: another authorised CASP, or a self-hosted wallet, where transfer is available for that asset and network. Which fits depends on whether you want a regulated provider to keep holding assets for you, or to hold them yourself.

Is there a deadline? There may be. ESMA requires a winding-down provider to communicate its timeline, including any deadline after which it would close remaining positions automatically. That date, if there is one, should be in your platform’s own wind-down notice, which is why reading it is on the checklist.
