Fraudsters and criminals are also not stupid people and they will use mixers and mix transactions. In the darknet, services charge 5-6% of the amount for such a service. Honest users who buy cryptocurrency on exchangers usually suffer from blocking. Exchanges don't write their policies. If your payment contains 2% "dirty" bitcoins or your payment contains 20% "dirty" bitcoins, then 2 payments can be blocked.
It is true that the criminals are not stupid people, while I made the above comment I was centered on mixers and exchanges and forgot about the darknet. It is becoming clearer than more innocent people will be indicted. The real criminals might never be caught.
After I read this from the article
Yet another amendment accepted on Tuesday to the Civil Jurisdiction and Judgments Act 1982 ensures courts across the U.K. can ask authorities to seize and freeze crypto tied to crime. Measures that will ensure seized assets aren't released until legal proceedings are concluded were also added to the bill.
This made me think how someone who is holding coins securely and offline with privacy would be tracked that he owns crypto to be sized.
It's good that there are still exchanges without KYC

https://www.crowdfundinsider.com/2023/07/209850-uk-financial-conduct-authority-updates-on-ongoing-eradication-of-illegal-crypto-atms/The Financial Conduct Authority (FCA) has issued a statement on its ongoing crackdown of crypto ATMs in the UK that are not authorized.
"The FCA says it has investigated 34 locations in the UK since the start of the year, typically working with other law enforcement agencies. So far, during 2023, 26 crypto ATMs have been shut down. 18 sites suspected of operating crypto ATMs across the UK were inspected over May and June by the FCA, South West Regional Organised Crime Unit, Bedfordshire Police, Hertfordshire Police, and the Metropolitan Police.
Steve Smart, Joint Executive Director of Enforcement and Market Oversight at the FCA explained that if you use an illicit crypto ATM, you may be giving your money to criminals, and you could lose all of your money."
