The fact that they are faceless makes it absolutely impossible to catch them, and also kind of impossible to recover stolen funds from them - they are very professional (if I should use that word).
So metawin have alot of hard work to do, in trying to recover theo stolen $4million, because majority's of that transactions where sent to personal Wallets which could be very hard to track.
Correct me if i am wrong, but crypto casinos usually have pretty good revenue, and $4 millions shouldn't be hard for bigger ones like metawin, and they are even getting it back.
Here's their latest volume according to dappradar:
I mean metawin is giving away >$700,000 weekly with their race prizes! Why would anyone think that they wouldn't have buffer money for emergencies? Stake was just hacked for $41 million last year and they didn't even get it back. But it didn't even make a scratch to them, because their revenue is so huge. This isn't 2015, when something like this would have been the end. These days sites are able to absorb way more financial losses.
