You making a list of what you think are scams claiming to protect people is lol if you just throw guesses at them. Prime dice has been paying out all winners. Show me someone who was scammed please.
They could have showed some evidence that the bets are legitimate, (e.g. a txid list) but they haven't, and they won't,
because they are a scam.
They may have paid out until now but the fact that they claim such amounts without any evidence is extremely disturbing and disingenuous, it implies that we should not doubt them only because they have said so.
This renders them a high risk casino in my eyes and I wouldn't bet in it.
