There are two important things that a casino has which can be a target for hackers, I learned this from the last discussion I started,
https://bitcointalk.org/index.php?topic=5538222.msg65280221#msg65280221The two are - Money which they have, and then the data they hold obtained from KYC.
There is concern about the two, but different levels of importance placed, I think. The data they hold and risk losing is more important to gamblers than the money the money they have, and then to the casino, I believe it will be that they have more importance to the money than the data of the many gamblers. Now based on this, do you feel a casino is more likely to be careless with people's data than they will with money to hackers because most hacks seem to target money they have more?
We do know about on how valuable personal informations are but as a hacker then you would definitely be targeting out on the money on which does a certain casino do have at the moment that they do have that chance on trying out to exploit or hacked out on a particular platform. If hackers could be able to bypass even further and get those informations then it will be just that an additional or add up into the money that they are getting into. Hackers could get that money plus informations by gamblers on which they can also make use into but most of the time they will be prioritizing for the funds on which that certain casino do have. For Casino's, perspective then both would be important and it is really just that there's nothing they can do at the moment or time that they've been hacked.
