Though Metawin is financially stable but still it is concerning for their security system. I don't know either they will get the previous place to the players or players will confuse about using Metawin. Hope they will be able to gain the previous trust of the players.
I do agree, hopefully they will patch things up with this hack, they are one of the biggest casinos and it's obvious that they are a target from his hackers. For sure, they have learned their lessons for this hack and this could be the last one. Of course, maybe players are going to be confuse, but they have gain the trust already, they have a solid customer base if I'm not wrong.
And for other casinos as well, they should also look at how Metawin was breached and they should also be on the alert, specially their support and fraud department to be on the lookup of this kind of attacks.
