Approximately 500 BTC was burned in for Chancecoin and there's $5+ billion in BTC that they could go after.
The idea that anyone smart (or rich) enough to hack Bitcoin would bother with betting with CHA is really funny.
We need more conspiracy theories, guys! (I don't mean you, superresistant).
It's not necessary that you take over a bit Bitcoin mining pool, it's sufficient that you merely be a big Bitcoin mining pool.
Ever saw pool operators try to harm altcoins before? Such an attack would cost them absolutely nothing.
I saw your posts on this topic before. Didn't one of developers said that protocol could be modified so that winners are declared slower (after a slightly (few min's) longer delay)?
I also read that tolerance for the maximum time skew among nodes on the network can be tightened, although I don't understand about it enough to be able to say whether it applies here.
It does't seem like something catastrophic. Of course the devs should have the last word, but as far as I am concerned it's enough to monitor the stats - if anyone's cheating even just a litte bit it'd be very easy to spot and then the devs upgrade the s/w to introduce those delays (unless the problem isn't fixable, which doesn't sound to be the case).
