Yes the way they handled the situation was ideal for a crypto related site.
They halted withdraws and they announced everywhere that they were hacked.
Most services wouldn't do this because it's damaging to their credibility, take MtGox and Cryptsy for example.
They got hacked and remained silent until they can into solvency issues.
I think this is not something that should be braggrd out. But in my point of view, this is somehow become a challenge to the hacker as well, they want to prove that they can solve it. And prove that primedice is not just big as the name outside but they also prove that they have really tight security as well. I do not say what they did is right or wrong but I just see in that way
