...seized and shut down despite its important role in advancing anonymous transactions.
It's not
despite of but
precisely because of "its important role in advancing anonymous transactions" that their site is seized. It's not like the authorities are shutting down something that's helping them implement the laws. They're shutting down something that's actually making their work hard. They don't like privacy and anonymity.
I'm surprised that despite eXch's claim that they have some friends in the intelligence sector, which precisely helped them decide to shut down their service in advance in a show of defensive move, there's still over 8 terabytes of data and €34 million left to be seized.
It made me curious. It doesn't even matter what these funds are for or these data are about, or whether they're incriminating or not. What's interesting is that they made their exit weeks ago and yet a considerable amount of data and a huge amount of money are still left when the authorities arrived.
