Who handles blockchain fraud cases?
-
I sold some Bitcoin through a peer-to-peer marketplace last year, and one of the buyers apparently used money connected to a fraud case. My exchange account is frozen now, and a federal agent called me with questions about the transfers. I didn't know anything about the buyer's situation, but the questions were specific enough that I don't want to answer them on my own. Where can I find an attorney who really knows crypto cases and won't need me to explain wallets, transaction hashes, and exchange records from scratch?

The fact that your name appears next to a wallet address doesn't prove what you knew about the buyer, but every message and transfer will be examined in that context. Don't move the coins around or delete any chats in an attempt to make the account look cleaner, because that could create another problem. Save the exchange notices, transaction IDs, bank statements, and the full conversation with the buyer. Let an attorney review everything before you send another explanation to the exchange or speak with the agent again.

A call from a federal agent takes this beyond a routine account dispute. You need someone who understands how investigators connect wallet activity to a person and how exchanges handle government requests. You can hire a cryptocurrency lawyer here https://arkadybukhlawfirm.com/practice-areas/cryptocurrency-and-crypto-law/ . Tell the attorney whether you received a subpoena, a seizure notice, or only a phone call. They can work out whether the government views you as a witness, a subject, or a target. That distinction will shape the response and the attempt to recover the frozen funds.
