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#msg65280221

The two are - Money which they have, and then the data they hold.

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?
