Proof of source of funds?

Hey, someone sent me a transaction that did'nt arrive to my wallet, I then get a email in the "junkmailbox" stating:

"Blockchain.com is operated by Blockchain Luxembourg S.A., authorized and regulated by the European Central Bank, with license number 4/10/21.3. 2011. The Company is registered in Luxembourg under full compliance of the CCA (Crypto Conduct Authority) with registered number 18697/77/D/91/19. Blockchain.com would anticipate that an individual's purchase and sale of cryptocurrency would often constitute investing activity (rather than a trade dealing in crypto assets). In these circumstances, a person who invests in digital assets will need to go through a procedure of verifying their finances through a functional blockchain system.

* Amount to be withdrawn: 1,665.00 EUR * Amount to be declared: 999.00 EUR * Liquidity percentage: - (Min. fee) * Duration time: 5 Bank days The client must deposit 999.00 EUR within scheduled time frame.

Deadline 11/06/2024 In order to avoid issues related to money laundering, and illegal activities, the client must disclose his banking institution, and crypto wallet.

The amount for declaration will not be utilized as an investment; in turn, the Crypto Conduct Authority, and the European Central Bank will require proof of deposit.

For the security and safety of both parties, every transaction will be carried out and safeguarded by a SMART CONTRACT and an ESCROW account. After the transaction has been fully processed via your personal verified wallet account, your withdrawal will be completed within 30 minutes, and added to your bank in full."

i have never heard of any POS that needs a payment... usually some kinde of legal documents..

this is really screwing with my head. I the wrote to the sender of the mail:

TO: ​[[email protected]](mailto:[email protected])​ Thu 2024-06-06 11:49

"Hello,

How can i complete the proof of source?What type of document do you need from me to release the transaction?"

Reponse:

"Hello,

Deposit to this escrow wallet to complete the AML-verification:

Will the BTC go back to the original address or no?

Greatful for any response in how to handle this. The receiving wallet was at Crypto.com wich i use regularly.

Thanks // J
