Dutch crypto broker Knaken (Rotterdam) abruptly shuts down, customers locked out of funds. This is why self-custody matters.

As of June 1st 2026, thousands of Dutch crypto holders woke up to find they could no longer log into their accounts on Knaken (NOT KRAKEN), one of the Netherlands' best-known crypto brokers.

The Rotterdam-based company abruptly took its website and trading app offline, with no word on whether or when customers will get their money back. Knaken says it halted all activity because it does not meet the new EU rules for crypto firms, known as MiCA (Markets in Crypto-Assets Regulation).

Users report having anywhere from a few thousand euros to tens of thousands of euros worth of crypto locked on the platform, with no clarity on when — or if — they'll get it back.

The AFM (Dutch financial markets regulator) confirmed awareness of the situation, noting that "crypto service providers that do not comply with MiCAR standards will find that their license application will not proceed." Knaken does not appear in the AFM's official crypto register, suggesting it was operating without a valid license.

Knaken was founded in Rotterdam in 2017, grew to around 45 employees, and sponsored football clubs including Feyenoord and Sparta.

A pretty well-established name in the Dutch market — which makes this even more of a gut punch for people who trusted them.

Now for the part that shouldn't need saying in 2026: self-custody.

"Not your keys, not your coins" is a cliché because it's true. Every single person locked out of their Knaken account right now owns coins they cannot touch — not because of a hack, not because of a market crash, but because a company made a regulatory mistake and pulled the plug overnight.

This isn't Mt. Gox. This isn't an exit scam (as far as we know). This is just a broker failing to get a license, and thousands of people paying the price for storing their crypto on someone else's infrastructure.

If your crypto lives on an exchange or broker — Knaken, Bitvavo, Coinbase, doesn't matter — you are trusting that company to:

Stay solvent

Maintain regulatory compliance

Not get hacked

Not shut down on a Friday evening without warning

A hardware wallet (Ledger, Trezor, Coldcard, etc.) costs €60–150. That's cheap insurance compared to having €10,000 in BTC frozen indefinitely.

Practical takeaways:

- Use exchanges/brokers only for buying. Withdraw to self-custody after.

- Check whether your broker is in your country's official crypto register (in NL: AFM's crypto register).

- Never keep more on an exchange than you're willing to lose access to — temporarily or permanently.

- MiCA is now the EU standard. If your broker isn't licensed, this situation can happen to you too.
