It would also help if anyone made a larger deposit/withdrawal recently, which might lead to the cold storage.
i havent back read yet to see what your saying but i know that bitdice is now one of the biggest casino's these days therfor i think they have a large bankroll to offer so we shouldnt worry about depo or withdrawing large amount of funds but only they can limit certain bets if they cant afford what you will be winning on a certain payout . if someone waggers big it does not mean that they also depo big but some can depo small and can wagger large enough using a good waggering strategy .
As to say that Bitdice do have records on paying out lots of huge wins without any problems or question asked.Unlike on others where you need some verification or blah blah before you can take out your winning.
