I am confused. You do not see that they obviously lied about having that bankroll? Or do you not see the problem with that lie?
I simply said that investment decisions are personal one, mine are diverse than yours and viceversa. Back to your questions, I worked with many businesses and a lot of them fear divulging their financial stats outside the company, even the most transparent one, also a common problem is also that many people in businesses fear backtracking from wrong statements, bad choices, etc because this could very often mean "losing their face", aka one's own sense of dignity or prestige in social contexts. To my understanding bitcointalk forum is a social context and, even if they may have realized their wrongs in not allowing a public display of cold storage addresses, they may fear losing their dignity and prestige into it thus preventing a public release of the cold storage addresses. IMO, I think the most sensible says is the dooglus one i quoted (below).
I don't want to comment on rest but the very first point: "it could be them withdrawing the same coins to their own wallet over and over again to make it look good" I think any one can now verify that using blockchain. One of the guys has already posted associated addresses with Da Dice wallet 
So this would just be speculation / allegation. Its not Da Dice's duty to proof anything, it duty of person who makes such allegations to prove it.

I was simply saying that without proof of solvency it *is possible* that they are insolvent. I don't need to prove that they are insolvent, and they don't need to prove that they are solvent. It would just look better for them if they could prove it. It still obviously wouldn't stop them from being able to steal everyone's coins, but it would at least instil extra confidence in potential investors.
