Considering the jackpot was specifically designed against conventions to not be provably fair, its not worth speculating about. The site is only getting 3 or 4 bitcoin wagered a day, which would mean that it's only making 0.03 BTC profit to be shared amongst investors. But of course the amount of faucet claims hugely exceeds that, and add in all the other expenses and no wonder they can't afford another jackpot winner, or if they do it'll just give it to a shill account.
It's a shame because it's actually a good site and I'd play here if they weren't so blatantly dishonest.
I do agree with the statement that they should provide the proof of their claimed bankroll, but thats no way to thrash them man.
Firstly, I don't think most jackpots are actually designed to be provably fair(you are free to tell me about one site that has provably fair jackpot, in dice to prove me wrong). I've been in the chat and on the site quite frequently, and personally I made 2.1btc from 0.28btc (but bust after I got too greedy), and I can vouch that the accounts that were credited were not shills(its the gut-feeling man) and if what you are saying is true sites with non-provably fair jackpot, all of them are scam right?
Secondly, faucet abusers are getting timered and in the extreme cases suspended and dadice funds the faucet themselves not from investor's money(AFAIK).
Thirdly, I don't know which "other expense" you are talking about, Signature campaign has been discontinued due to dadice spending much on them and people being suspicious over their "generosity".
Lastly, being suspicious is good, you may escape from a scam or two but the statements you just made, its making me wonder
you are actually shilling here(maybe). Aaand lastly, here is their hot wallet
https://blockchain.info/address/1HMAgvunJzr3HoRAUFg3VuU2UJm9KWDjFu . They have paid out more than 180btc (according to the stats), and guiness has been paid 20btc for his 9900x win too(now don't tell me that was faked too).
Over and out!
