User adilx157 was mixing his coins and didn't receive anything because of the take down.
Will the Europol return his coins? I doubt it.
But it's fine for the EU autorithies to literally scam people who are looking for on chain privacy. Nice!
I believe there are many users who have lost their assets, like this user who lost his funds due to what happened last week in November. The amount that was confiscated is indeed substantial , and I don't expect this user or anyone else to be able to recover their assets after all the stored mixer assets were legally seized..
As for me, if I were in their position, I would accept the loss and move on, as I'm not the only one affected.. However, one could try hiring a lawyer and explaining the whole story and providing clear evidence that the mixer was used legally and not for any illegal activities. Then, The lawyer could file a report with the relevant authorities, although I doubt this would lead to a completely satisfactory result.
