The problem is that every site (bashing dadice here) took its time to issue cold storage, and I know this for a fact starting from PRC

I mean cut some slack here guys! If they are so threatened by Da Dice why don't they just close their own shops.
...again Those who live in glass houses shouldn't throw stones.
Not true. Just-Dice had proof-of-solvency since launch.
It's not about being threatened, it's about warning the community of a likely scam.
If the site is solvent then there is a simple solution to this ... demonstrate it!
