Actually, there is one thing which is kind of interesting - though maybe in a reverse way.
When Dwolla received a seizure warrant for MtGox's account back in May people assumed it was "an attack on Bitcoin".
"The Department of Homeland Security and US District Court for the District of Maryland issued a ‘Seizure Warrant’ for the funds associated with Mutum Sigillum’s Dwolla account (a.k.a. Mt. Gox)," a Dwolla spokesperson told NYO's BetaBeat. "Dwolla has ceased all account activities... for Mutum Sigillum while Dwolla’s holding partner transferred Mutum Sigillum’s balance, per the warrant."
It isn't yet clear why this seizure happened, and Dwolla isn't saying anything beyond confirming the court order. Mt. Gox didn't immediately responded to an inquiry from Ars about the seizure. A user on Bitcoin StackExchange published this short reply received from an inquiry to Mt. Gox about the shut-down: "Thank you for the e-mail. We can see that the Dwolla transactions are not getting processed right now. We will contact Dwolla and post an announcement regarding this. Your patience is appreciated till then."
A DHS spokeswoman declined to comment on the case, "in order not to compromise this ongoing investigation being conducted by ICE Homeland Security Investigations (HSI) Baltimore."
The grand jury indictment against DPR was issued in Maryland and court records related to that case go back to May - some of them remain unsealed.
